Shopping Center Attack: Why I Care

Posted on September 20, 2016 by Brian H. Gill

Saturday night’s attack in a St. Cloud shopping center was uncomfortably close to home. Crossroads Mall is about an hour down the road from where I live, and a place I’ve enjoyed visiting.

Only one person died, the attacker: a 22 year old St. Cloud-area student.

  2. “Let’s Spread Love, not Hate”

Caring About Human Life

The incident hasn’t exactly been headline international news, but the attention it’s gotten is impressive, considering what else has been going on:

Getting back to what happened in St. Cloud, I’m still upset about the attack: and sorry that the attacker is dead. That, I’d better explain.

I believe that human life is sacred: all human life. Each of us has equal dignity: no matter where we are, who we are, or how we act. (Catechism of the Catholic Church, 360, 1700–1706, 1932–1933, 1935, 2258)

Murder, deliberately killing an innocent person, is wrong. (Catechism, 2268–2269)

Maybe the young man didn’t really mean to kill anyone: but what he was doing with a knife apparently looked like murderous attacks. I can’t say that I am sorry that his attacks were stopped.

But I do regret that he is dead.

His actions disturbed his community, which is uncomfortably close to mine. If he had lived, it’s possible that he could have made some reparation, “paying” in some way for his actions; and helping to heal his community.

One of these days I’ll talk about justice, the common good, and all that. But not today. (Catechism, 1905–1912)

Why should I care? Like I keep saying: I should love God, love my neighbor, see everybody as my neighbor, and treat others as I’d like to be treated. (Matthew 5:43–44, 7:12, 22:36–40, Mark 12:28–31; Luke 6:31, 10:25–27, 29–37; Catechism, 1789)

Somali-Americans and Leviticus

He was a Somali-American, born in Kenya. There’s been a civil war in Somalia since around 1990, which encouraged many families to get out while they were still alive. Many of them came to America — mostly Minnesota.

Some will probably decide to move back, when and if things settle down in the old country. I hope some decide to stay: if for no other reason than that I haven’t had a chance to try their coffee yet.

Part of my attitude toward Somali-Americans comes from my family background and personal experience. But even if I wasn’t inclined to accept folks who don’t look and act exactly like me: I’d be obliged to cultivate that acceptance:

“The more prosperous nations are obliged, to the extent they are able, to welcome the foreigner in search of the security and the means of livelihood which he cannot find in his country of origin. Public authorities should see to it that the natural right is respected that places a guest under the protection of those who receive him.

“Political authorities, for the sake of the common good for which they are responsible, may make the exercise of the right to immigrate subject to various juridical conditions, especially with regard to the immigrants’ duties toward their country of adoption. Immigrants are obliged to respect with gratitude the material and spiritual heritage of the country that receives them, to obey its laws and to assist in carrying civic burdens.”

(Catechism, 2241)

An ‘open door’ immigration is not a new idea:

“You shall not oppress an alien; you well know how it feels to be an alien, since you were once aliens yourselves in the land of Egypt.”
(Exodus 23:9)

” ‘When an alien resides with you in your land, do not molest him.

“You shall treat the alien who resides with you no differently than the natives born among you; have the same love for him as for yourself; for you too were once aliens in the land of Egypt. I, the LORD, am your God.”
(Leviticus 19:33–34)

“For I was hungry and you gave me food, I was thirsty and you gave me drink, a stranger and you welcomed me,”
(Matthew 25:35)

About Catechism, 2268–2269, and the newcomer’s obligation “to obey its laws and to assist in carrying civic burdens” — it looks like many Somali-Americans in St. Cloud are as upset about the young man’s actions as I am.

More so, since they’re still at the stage my ancestors were, just a few generations back: trying to convince ‘regular Americans’ that they’re new neighbors, not threats. More of that below, under “Let’s Spread Love, not Hate”.

1. Death in a Shopping Center


(From AFP, via BBC News, used w/o permission.)
(“Dahir A Adan had been in the US for 15 years, his father said”
(BBC News))

“Minnesota mall knifeman was student, says father”
BBC News (September 19, 2016)

“A knifeman who stabbed nine people at a Minnesota shopping centre at the weekend has been identified by his father as a 22-year-old student.

“Dahir A Adan is a Kenyan-born ethnic Somali who had been in the US for 15 years, his father told the Minneapolis Star Tribune.

“He said he had ‘no suspicion’ that his son was involved in extremist activity….

“…The Islamic State group claimed responsibility. Rasd, a news agency linked to the group, claimed on Sunday the Minnesota attacker was a ‘soldier of the Islamic State’.

“The attacker, who was dressed in a security uniform and carrying what appeared to be a kitchen knife, reportedly made at least one reference to Allah and asked a victim if he or she was Muslim before attacking, said police.

“Adan had been working as a security guard for the mall’s Electrolux Home Products store, according a company spokeswoman….”

We still don’t, as far as I’ve read, know why Dahir1 A Adan decided to attack those folks. What does seem clear is that he cut or stabbed several people at a shopping mall, and was killed by an off-duty police officer.

I’m sorry that those folks got hurt, and that young Mr. Adan is dead. But I’m not going to denounce Crossroad Mall for inciting violence against shoppers, or call for stronger anti-knife legislation.

There’s been enough craziness this year:

“The Least Force Necessary”

I went over legitimate defense on September 11, 2016.

I’m allowed to avoid or resist the attack; using the least force necessary. The same principle applies to groups of people. (2263–2267, 2307–2317)

Ideally, someone would have found a way to restrain Dahir A Adan, not kill him. But everything I’ve read says that he started this mess, attacking folks with a knife.

I’m not going to criticize someone for protecting innocent shoppers: particularly since a knife, even a “kitchen knife,” can be a lethal weapon. It’s a wonder that more folks didn’t end up hospitalized.

Non-lethal weapons have been moving out of pulp science fiction and into research and development. But even those are controversial, and that’s another topic.

2. “Let’s Spread Love, not Hate”


(From Jared Goyette, via The Guardian, used w/o permission.)
(“Somali-American leaders hold a press conference in St Cloud, Minnesota, to address the mass stabbing attack of Saturday night.”
(The Guardian))

“Somali-American leaders speak out in press conference”
Ben Rodgers, St. Cloud Times (September 18, 2016)
(Includes video)

“A group of St. Cloud Somali-American leaders, as well as other community leaders, spoke out in a nationally televised press conference on Sunday afternoon at Lake George.

“The press conference came after an incident Sunday night involving a stabbing attack at the Crossroads Center in St. Cloud. The community leaders used it as an opportunity to stress the attack was perpetrated by a single individual, that it does not represent the Somali-American and Muslim community and to express support for the victims….

“…Mohamoud Mohamed, executive director of the St. Cloud Area Somali Salvation Association: ‘They are minorities in our faith that are misusing the credibility of our faith. Islam is peace.’

“Lul Hersi, member of the St. Cloud Somali-American community: ‘Let’s unite as one Minnesota. Let’s take love instead of hate. Let’s preach the good of us, not the bad that happens just once in a while. … I said last night, not in St. Cloud. That is what I told my kids, not in St. Cloud. I hope my neighbors, my co-workers, my friends, my community member, my elders and other take this to heart. Let’s spread love, not hate.’

“The Rev. Randy Johnson, pastor at First United Methodist Church: ‘As Christian leaders we have come to gather with our brothers and sisters who are Muslims on this day to say the work will continue. That peace is our goal and we will continue together to make this a community that is known throughout this nation as a community that never quits working for peace.’…”

The press conference isn’t the highest-profile item around, no surprise considering how much else has been happening, but it’s getting a bit of attention:

Some of the bad news is good news, sort of, from the ‘you’re known by the enemies you make’ viewpoint —

“…Jaylani Hussein, the executive director for the Minnesota chapter of the Council of American-Islamic Relations, said central Minnesota has a history of anti-Muslim organizing. He pointed to a string of incidents dating back years, including visits by well-known anti-Muslim speakers and a recent billboard, eventually removed, that read ‘Catholic Charities Resettles Islamists, Evil or Insanity.’…”
(Associated press, via ABC News)

I don’t know which “Catholic Charities” the billboard folks had in mind. There’s Catholic Charities of the Diocese of St. Cloud and of St. Paul and Minneapolis, among others.

According to the Minneapolis Star-Tribune, it was a complaint by the St. Cloud Catholic Charities that encouraged Franklin Outdoor to take the message down.

There’s an interesting conflict between freedom of expression, civic responsibility, and common sense involved: but I can’t say that I’m sorry to see that particular bit of anti-Catholic xenophobia gone.

Tolerance and Hope

Over the centuries, America’s government and has showed an increased tolerance of non-English, non-Protestant Americans.

I see that as a good thing, partly because many of my ancestors are of ‘low type.’2 I’m nearly half Irish.

Most Americans eventually realized that many if not most Irishmen were not violent drunkards with criminal tendencies.

I’m pretty sure that a century from now most of us will have gotten used to the descendants of today’s immigrants. And, most likely, a few will be upset about some other bunch of newcomers.

My hope is that folks with get-up-and-go will keep getting up and going: to America. I think we all benefit when folks add new ideas and fresh enthusiasm to America’s mix.

More of my take on:

1 On a poignant note — apparently the name Dahir, or Daahir, comes from a Somali word meaning “pure” or “religiously pure.”

My native culture was more apt to give girls names like Chastity or Katherine — which may or may not be from Αικατερινη. Tohar, טוֹהַר, apparently means “pure,” but I’ve never run into someone with that name.

“The Iberians are believed to have been originally an African race, who thousands of years ago spread themselves through Spain over Western Europe. Their remains are found in the barrows, or burying places, in sundry parts of these countries. The skulls are of low prognathous type. They came to Ireland and mixed with the natives of the South and West, who themselves are supposed to have been of low type and descendants of savages of the Stone Age, who, in consequence of isolation from the rest of the world, had never been out-competed in the healthy struggle of life, and thus made way, according to the laws of nature, for superior races.”

SETI and Life’s Ladder

Posted on September 18, 2016 by Brian H. Gill

I’d be surprised if many folks took movies like “Earth vs. the Flying Saucers,” “Invaders from Mars,” and “Plan 9 from Outer Space,” seriously: as something other than entertainment, anyway.

All of which has about as much to do with space exploration, astronomy, and SETI, as “Keeping Up with the Kardashians” does with family counseling.

I’ll be talking about SETI, the search for extraterrestrial intelligence; the Fermi paradox; and whatever else comes to mind — but first, the Copernican principle, which arguably sounds cooler than the mediocrity principle.

That’s the idea that Earth isn’t the center of the universe, and that conditions here aren’t unique. One of these days I’ll probably talk about Anaximander and the Ptolmaic system, but not today.

I think Earth is special, for the same reason I think Minnesota is special. I live here.

But I also think we’ve been finding the same elements, and same physical laws, throughout the universe. We’ve also been learning that the universe has been changing since it started, some 13,799,000,000 years back, give or take.

So there’s some truth in the Copernican principle. Which makes the lack of space alien visitors remarkable.

Where is Everyone?

The Fermi paradox — both Enrico Fermi and Michael H. Hart raised the question, I don’t know why it’s named after Fermi — is a nifty name for the ‘where is everybody’ question.

It’s a reasonable question.

That’s because many of this galaxy‘s 100,000,000,000-plus stars have planets somewhat like Earth.

Some fraction of those planets may support life, which might lead to intelligent life. Some of those planets are billions of years older than Earth.

Folks who are anything like us could have sent interstellar probes here from the other side of the galaxy in about a million years. That’s a very short time, on a cosmic scale.1

A few of our spacecraft are already headed out of the Solar System, sending back data about conditions beyond the heliosphere.

If we had neighbors, and they’re anything like us, the assumption is that we’d have found at least the alien equivalent of 50-gallon oil drums and six-pack rings by now. We haven’t.

Folks have quite a few explanations for this lack of evidence, some more plausible then others:

  1. Extraterrestrial life is rare or non-existent
  2. We’re the only intelligent life
  3. Everybody else is low-tech
  4. Intelligent life
    • Destroys itself
    • Destroys other intelligent life
    • Gets killed by natural events
  5. We’re the first
  6. It’s a big universe
    • Intelligent civilizations are too far apart in space or time
    • The Galaxy is too big for us to meet each other
  7. We haven’t been around long enough
  8. We’re not listening properly
  9. Civilizations broadcast detectable radio signals only for a brief period of time
  10. Civilizations tend to isolate themselves
  11. The aliens are too alien
  12. Everyone is listening, no one is transmitting
  13. They’re avoiding us
    • We’re in a
      • Zoo
      • Wildlife preserve
      • Terrarium
    • They’re afraid of us
  14. They’re already here
    • And hiding
    • But the government/Big oil/Microsoft/The Illuminati won’t let us know

Like I keep saying, I don’t believe that life exists elsewhere in this universe, or that it does not. We don’t know, not yet.

If we do have neighbors, and we meet, I’m pretty sure that some folks will be upset, and that others will realize that the people from another world are — people.

That doesn’t mean that I think they’ll be particularly “human,” and that’s a topic for another post.

Scala Naturae: The Ladder of Nature

Depending on who’s talking, that’s a diagram of the scala naturae, ladder of nature/life, or chain of being.

It’s been around in one form or another for quite a while, and can be a handy way to categorize things.

Plato wrote about the father-son relationship; the nature of knowledge and opinion, perception and reality, nature and custom, and body and soul; and art.

He didn’t discuss cosmology much, although Pythagoras had called the order of the universe κόσμος, cosmos decades before Plato was born.

Alexander von Humboldt dusted the Pythagorean word off and used it as the title of his “Kosmos” about two dozen centuries later — and that’s another topic.

Plato did write about metaphysics and his theory of forms. That’s the idea popularized by Plato’s Allegory of the Cave. Maybe “popularized” is putting it a bit strongly, but my guess is that you’ve heard of Plato’s cave.

Skipping lightly over Aristotle, Plotinus, and Neoplatonism, which hasn’t been new since Saint Augustine of Hippo wrote “De libero arbitrio,” and that’s yet another topic.

Where was I? “Invaders from Mars,” the Fermi paradox, Plato’s theory of forms. Right.

Anyway, Neoplatonism includes a celestial hierarchy which arguably goes back to Aristotle’s idea of the The Great Chain of Being/Scala Naturae/Ladder of Life.

Sharing a Rung with Cousins

We’ve learned a great deal since Aristotle’s day, so these days we divide living creatures into domains and kingdoms, two of which are plants and animals; but I think the “ladder” model is good enough for this post.

Humans are animals, living creatures with a material body. But we’re not just animals.

Each of us is an animal with free will who can think; a ‘someone,’ not a ‘something.’ We can decide what we do or do not do. It’s being rational creatures that makes us “in the image of God.” (Genesis 1:27; Catechism of the Catholic Church, 1700–1706, 1730, 1951)

Getting back to the “ladder,” we’re material creatures. In that way, we’re like rocks, plants, and animals. We’re also people: able to think and decide what we do.

If we meet folks who aren’t human, intelligent creatures made from the stuff of this universe, they’d be on the same ‘rung’ of the ladder as we are.

I think Brother Guy Consolmagno is right: they’d be so much like us, basically, that they’ll be more like cousins than “aliens.”2

More-or-less-related posts:

1 Lets see how many years ago a few key events happened:

  • 13,799,000,000 – universe starts
  • 4,540,000,000 – Earth forms
  • 4,100,000,000 – life starts on Earth
  • 2,600,000 – Oldowan stone tools made
  • 39 – Voyager 1 launched

Voyager 1 is currently about 20,200,000,000 kilometers from our sun, outward bound and still sending back data. That’s a tiny fraction of the distance to the nearest star. But if other folks were launching their first space probes while we were making our first stone chopping tools, today they could be using tech we’ll be developing 2,600,000 years from now. 2,600,000 years seems like a long time, but it’s less than one one-thousandth (26/45,400) Earth’s age.

2 From “Brother Astronomer;” Chapter Three, Would You Baptize an Extraterrestrial? — Brother Guy Consolmagno (2000)

“…Frankly, if you think about it, any creatures on other planets, subject to the same laws of chemistry and physics as us, made of the same kinds of atoms, with an awareness and a will recognizably like ours would be at the very least our cousins in the cosmos. They would be so similar to us in all the essentials that I don’t think you’d even have the right to call them aliens.”

ESA’s Gaia, HD 164695, and SETI

Posted on September 16, 2016 by Brian H. Gill

Scientists working with ESA’s Gaia space observatory published the first part of a three-dimensional sky map this week. It’ll be the most comprehensive all-sky survey done so far.

Not unexpectedly, this year’s ‘ET calling’ headlines gave way to something slightly more down-to-Earth.

We may eventually pick up an artificial signal from the stars: but that burst of radio noise from the direction of HD 164695 was almost certainly due to a clerical error of sorts. It wasn’t our first false alarm, and I doubt it will be the last.

  1. Gaia’s Map Takes Shape
  2. False Dawns
  3. SETI and an Unregistered Satellite
  4. HD 164595, Speculation, Miscellany

Life in the Universe?

It’s among my favorite ‘flying saucer’ jokes. The lurid accounts of wrecked spaceships and alien autopsies at Area 51 are an elaborate cover story, concealing the installation’s true purpose: storing and analyzing a wrecked alien spaceship and its deceased crew.

My interest in SETI, the search for extraterrestrial intelligence, which doesn’t have much to do with the Roswell UFO incident, prompted me to participate in a highly-unscientific poll earlier this year.1 I was the 55,742th respondent.

The current results are about the same as they were then:

  • “Do you believe alien life exists elsewhere in the universe?”
    • Yes – We may not have found them yet, but they’re out there
      65% (145,192 votes)
    • No – Aliens are just part of science fiction
      20% (43,894 votes)
    • I’m not sure
      15% (32,726 votes)
      (Space.com)

I’m still in the 15% minority.

Maybe that seems odd, since the Bible doesn’t mention space aliens: and I’ll get back to that.

God’s God, I’m Not

I’m a Catholic, so I believe God is infinite and eternal, almighty and ineffable: beyond our power to describe or understand. (Catechism of the Catholic Church, 202, 230)

I also believe that God is creating a good and ordered physical world; and that this universe is changing, in a state of journeying toward an ultimate perfection. (Catechism, 282–308)

Studying this immense and ancient creation honestly and methodically cannot interfere with an informed faith, because “the things of the world and the things of faith derive from the same God.” (Catechism, 159)

Whether or not we have neighbors isn’t, as I’ve said before, my decision. God’s God, I’m not, and I’m okay with that.

Astrobiology and Psalms 111:2

Before rambling on about HD 164695, radio signals, and space aliens, here’s how the Pontifical Academy of Sciences’ 2009 Study Week on Astrobiology2 booklet began — plus something from Psalms.

“…Among my Predecessors of venerable memory there were some who studied this science, such as Sylvester II who taught it, Gregory XIII to whom we owe our calendar, and St Pius X who knew how to build sundials. If the heavens, according to the Psalmist’s beautiful words, ‘are telling the glory of God’ (Ps 19[18]: 1), the laws of nature which over the course of centuries many men and women of science have enabled us to understand better are a great incentive to contemplate the works of the Lord with gratitude.
Benedict XVI, Angelus, St Peter’s Square, Fourth Sunday of Advent, 21 December 2008

“Introduction
Prof. JONATHAN I. Lunine, chair of the Scientific Organizing Committee
Dr. José G. Funes, S.J., Director of the Vatican Observatory

“Astrobiology is the study of life’s relationship to the rest of the cosmos: its major themes include the origin of life and its precursor materials, the evolution of life on Earth, its future prospects on and off the Earth, and the occurrence of life elsewhere. Behind each of these themes is a multidisciplinary set of questions involving physics, chemistry, biology, geology, astronomy, planetology, and other fields, each of which connects more or less strongly to the central questions of astrobiology. Stimulated by new capabilities for scientific exploration on and off the Earth, astrobiology seems to be establishing itself as a distinct scientific endeavor….

“…Ultimately, much of the fascination of astrobiology comes from the question of whether sentient life forms exist on other worlds, and whether forms of life alien to our own in fact coexist with us – today – on our own home world. Session 8, Intelligence Elsewhere and Shadow Life, explores both these issues. The search for intelligent life elsewhere is being conducted by listening to the cosmos with radio telescopes in an effort to pick up a signal of inarguably artificial origin. A search for life with a biochemistry different from that of all the known life on Earth – what has been termed ‘shadow life’ – on our own planet is a fascinating possibility but one fraught with daunting difficulties.

“Astrobiology is an effort to use a diverse range of scientific techniques, focused on targets from the molecules in cells to the vast cosmos around us, to provide a deeper appreciation of humankind’s place in the cosmos. It is a recognition of the remarkable intricacies of all that is within and around us and a 21st century realization of the psalmist’s recommendation (Ps 111:2) to delight in its study….”
(“Study Week on Astrobiology,” Pontifical Academy of Sciences (November 6-10, 2009))

“Great are the works of the LORD, to be treasured for all their delights.”
(Psalms 111:2)

1. Gaia’s Map Takes Shape


(From ESA, via BBC News, used w/o permission.)
(“Gaia’s first sky map”
(ESA))

“Gaia space telescope plots a billion stars”
Jonathan Amos, BBC News (September 14, 2016)

“The most precise map of the night sky ever assembled is taking shape.

“Astronomers working on the Gaia space telescope are releasing a first tranche of data recording the position and brightness of over a billion stars.

“And for some two million of these objects, their distance and sideways motion across the heavens has also been accurately plotted.

“Gaia’s mapping effort is already unprecedented in scale, but it still has several years to run.

“Remarkably, scientists say the store of information even now is too big for them to sift, and they are appealing for the public’s help in making discoveries.

“A web portal has been opened where anyone can play with Gaia data and look for novel phenomena….”

The European Space Agency’s Gaia mission is a followup to their 1989-1993 Hipparcos mission that gave us the 118,218-entry Hipparcos Catalog.

If all goes well, the Gaia catalog will have around 1,000,000,000 entries: 1% of the Milky Way galaxy’s stars, give or take, plus thousands of Jupiter-sized exoplanets.

If the name Gaia sounds familiar, you know your ’90s cartoons. Whoopi Goldberg (1990-1993) and Margot Kidder (1993-1996) voiced Gaia, the anxious Earth-goddess in Captain Planet and the Planeteers.3

Getting back to the ESA’s space observatory, “Gaia” started an acronym: Global Astrometric Interferometer for Astrophysics. The original idea was that they’d use interferometry, measuring how light waves overlap.

They eventually decided that measuring stellar paralax, how much a star shifts position against more distant objects, was a better idea; but kept the “Gaia” name “to provide continuity with the project,” as ESA put it.

There’s an ESA’s Gaia resource link list near the end of this post.

2. False Dawns


(From BBC News, used w/o permission.)
(“The Allen Telescope Array, which has joined the search for possible alien radio signals”
(BBC News))

“The wrong turns and false dawns in Earth’s search for alien life in the universe”
Alex Partridge, BBC News (August 31, 2016)

“There was excitement this week when it emerged a Russian radio telescope had detected a strong signal coming from the direction of a star 95 light years away from Earth.

“Could alien life finally have been found?

“The signal was detected by the RATAN-600 telescope, in the town of Zelenchukskaya near the Georgian border, last May.

“At the time, the telescope was pointed in the direction of a star called HD 164695.

“It’s a similar size to our sun but is only known to have one gassy, Neptune-like planet orbiting it….”

I didn’t pay much attention to this ‘alien signal’ story at first, partly because it peaked in late August: along with other ‘silly season’ news.4

A few decades back, that would be when more than the usual quota of alien abduction and Elvis sighting stories would spill over from grocery checkout lines.

I might have ignored it entirely, but the headlines were starting to look interesting:

I didn’t know what to expect from the Forbes op-ed; and was less than impressed when Dr. Miller cited a science fiction novel, “The Three Body Problem,” as an authority.

Don’t get me wrong: I like science/speculative fiction, but realize that ‘good enough for a story’ ideas don’t necessarily work in real life.

Secrecy, Religious Polarization, and Phyllosilicate Minerals: a Digression

Dr. Miller figured this is what we could expect, if someone got solid evidence that we’ve got neighbors:

  1. Secrecy
    • for as long as it could be maintained
  2. Authoritarianism
    • An almost war footing for governments as they try to work through implications
  3. Religious polarization
    • The religious spectrum polarized more dramatically towards the poles
  4. Societal shift.
    • A shift in sciences, resurgence for evaluating cultural differences, language, humanities, and communications

I’m not sure what he meant by “evangelicals” in his discussion of “religious polarization.” If it’s his polite way of saying Bible thumpers, he’s probably right:

“….Not a complete shift, but more evangelicals, and more hard-core atheists. The people in those categories become more extreme; those in between are annoyed by them….”
(John L. Miller, via Forbes)

I put an excerpt from Dr. Miller’s piece, including an extended version of that list, near the end of this post.5

Some of that “polarization” popped up last summer, when “Earth 2.0,” Kepler-452b, was in the news. I’ve quoted this before. (July 29, 2016)

“Earth 2.0: Bad News for God”
Jeff Schweitzer, Huffington Post (July 23, 2015)

“…Let us be clear that the Bible is unambiguous about creation: the earth is the center of the universe, only humans were made in the image of god, and all life was created in six days. All life in all the heavens. In six days….”

From the tone of Dr. Schweitzer’s op-ed, I suspect that the only Christians he encountered were wholeheartedly convinced that their version of the Bible was literally, word-for-word, true.

Like I’ve said before, I’m a Catholic: so I must take Sacred Scripture seriously. It’s ‘Catholicism 101’ — and then some. (Catechism, 101–133)

But I don’t have to believe that the creation story in Genesis 1:1–2:4 and the one in Genesis 2:4–7 are both literally word-for-word true.

That’s just as well, or my faith would be threatened every time I see something other than phyllosilicate minerals — literal clay — when I check my blood sugar; and I’ve said that before. (July 15, 2016)

Martian Canals and a Microwave Oven

Alex Partridge — I’m back to the BBC News item now — skips lightly over Giovanni Schiaparelli’s observations of Mars and how “canali” became “canals.”

Percival Lowell had a lot to do with it, and I’m skipping lightly over the matter, too.

Partridge discusses three other “wrong turns and false dawns:” the 1977 “Wow! signal,” a radio signal detected at Ohio State U.’s Big Ear; a 17-year intermittent transmission from a break room’s microwave; and the whatsit around KIC 8462852.

He didn’t, however, mention 19th-century proposals for signalling Mars, Nikola Tesla, or PSR B1919+21 — and neither will I. Not today. I’m leaving that for another post.

3. SETI and an Unregistered Satellite


(From nat-geo.ru, via SETI Institute, used w/o permission.)
(“The RATAN-600 radio telescope”
(SETI Institute)

“A SETI Signal?”
Seth Shostak, Senior Astronomer; SETI Institute (August 30, 2016; updated August 31, 2016)

“…The signal seems to have been discussed in a presentation given by several Russian astronomers as well as Italian researcher, Claudio Maccone, the chair of the International Academy of Astronautics Permanent SETI Committee. Maccone has recently sent an email to SETI scientists in which he describes this presentation, including the signal ascribed to star system HD 164595….

“…So what’s the bottom line? Could it be another society sending a signal our way? Of course, that’s possible. However, there are many other plausible explanations for this claimed transmission – including terrestrial interference. Without a confirmation of this signal, we can only say that it’s ‘interesting.’ “

My hat’s off to the SETI Institute for that ‘wait and see’ attitude.

It looks like the signal did come from space: but wasn’t sent by space aliens.

Director of the Institute of Applied Astronomy at the Russian Academy of Sciences Alexander Ipatov explained that the RATAN-600 radio telescope had been pointed at HD 164595 and an unregistered Soviet-era satellite when that signal came in.

“…’We, indeed, discovered an unusual signal. However, an additional check showed that it was emanating from a Soviet military satellite, which had not been entered into any of the catalogs of celestial bodies,’ Ipatov said….”
(Tass (August 30, 2016), quoted by the SETI Institute)

If this was a science fiction story, we’d be in Dr. Miller’s first and second stages now: secrecy and authoritarianism. I’ve enjoyed yarns like that, but think Ipatov is probably right.

Various nations launched roughly 6,600 satellites since Sputnik 1 went up. A little over half are still in orbit, and about 1,000 are still in operation.

One of the Soviet Union’s military satellites, with its transmitter switched on, crossing in front of HD 164595, seems likely enough. The folks at RATAN-600 would, ideally, have known about every satellite ever launched; but we don’t live in an ideal world.

HD 164595 is a great deal like our sun: spectral type is G2V D, compared to our star’s G2V; with pretty close to the same temperature, mass, and metallicity. That last item, metallicity, is the fraction of its mass that’s not hydrogen or helium.

HD 164595’s single known planet, HD 164595 b, isn’t particularly Earth-like.

Its year is about 960 hours long, roughly 40 days; the planet’s mass is 16.14 times Earth’s, give or take; and the temperature is right around 5,790K: over 9,900 degrees Fahrenheit, 5,500 Celsius. That’s almost hot enough to boil tungsten.

There could be an Earth-like planet farther out, but no: this does not look like a ‘first contact’ situation.

4. HD 164595, Speculation, Miscellany


(From ESO, via CNN News, used w/o permission.)
(“Mysterious signal not from aliens, scientists say”
(CNN))

“Hear me now? ‘Strong signal’ from sun-like star sparks alien speculation”
James Griffiths, CNN (August 30, 2016)

“Astronomers engaged in the search for extraterrestrial intelligence (SETI) are training their instruments on a star around 94 light years from Earth after a very strong signal was detected by a Russian telescope.

“An international team of researchers is now examining the radio signal and its star, HD 164595 — described in a paper by Italian astronomer Claudio Maccone and others as a ‘strong candidate for SETI’ — in the hopes of determining its origin.

” ‘The signal from HD 164595 is intriguing, because it comes from the vicinity of a sun-like star, and if it’s artificial, its strength is great enough that it was clearly made by a civilization with capabilities beyond those of humankind,’ astronomer Douglas Vakoch, president of METI International, which searches for life beyond Earth, tells CNN….”

The article also quotes Vakoch on the odds that this was a signal from the stars:

“…’Without corroboration from an independent observatory, a putative signal from extraterrestrials doesn’t have a lot of credibility,’…

“…’the greatest limitation of the May 2015 signal is that it hasn’t been replicated. Before we can give any credence to a signal as coming from extraterrestrials, we need to see it repeatedly to make sure it wasn’t just a transient phenomenon.’

” ‘It deserves at least a few hours of observing time by SETI researchers at other locations to make sure we don’t miss an opportunity to make first contact, however remote.’…”
(James Griffiths, CNN)

He also mentioned gravitational lensing, where light from a distant source gets focused when it passes by a closer mass. Like I said about the SETI Institute, my hat’s off for METI’s ‘wait and see’ attitude.

Neither outfit was just waiting, though. METI and SETI International were making followup observations of HD 164595 at the Optical SETI Observatory, and Allen Telescope Array: with no positive results.

If that two-second pulse — the chart is from Paul Gilster at Centauri Dreams, via Wikimedia Commons — had come from near HD 164595, the transmitter would have been very powerful.

That’s what fueled speculation that it was an “isotropic beacon from a Type II civilisation.” (Wikipedia)

An isotropic beacon is, or would be, a transmitter that sends an unmodulated signal in all directions. Folks who could tap a star’s energy output, all of it, to broadcast static might use one to get attention.

That strikes me as a remarkably inefficient use of resources.

Which gets me to Type II civilizations and the Kardashev scale.

The Kardashev Scale and Pheromone Trails

Astronomer Nikolai Kardeshev came up with it in 1964, and it’s been extended since then.

I agree with folks who say the Kardashev scale isn’t universally useful because folks who aren’t human — may not act like us.

On the other hand, it’s a handy way to think about what sort of civilizations could exist. Kardeshev’s scale sorts hypothetical civilizations by how much energy they can store and use:

  • Type I
    All energy reaching their planet from their sun
  • Type II
    Energy of the entire star
  • Type III civilization
    Energy on the scale of its entire host galaxy

On this scale, we’re working our way up to Type I.

Then there’s XKCD’s commentary on our efforts to find intelligent life in the universe.

More of my take on:

In case you haven’t had enough of SETI, exoplanets, and all that, I put a sincerely-excessive number of resources in a ‘background‘ link list at the end of this post.

1 That’s the “Starshot, SETI, and the Universe” post, back on Blogger. (April 15, 2016)

The ‘do you believe’ poll was under Still Searching for Neighbors — “Belief in Extraterrestrial Life:” Certainty, Uncertainty, and Religious Affiliation, and here’s a link to the article that got me started:

2 Extraterrestrial life, science, and the Vatican:

3 Gaia is also the ancient Greek version of Mother Earth, and Gaianism is what happened when 20th-century environmentalism got mixed up with New Age grooviness.

I’m a Catholic, so I see letting anything — money, politics, pleasure, family, fame, whatever — except God take first place in my priorities as a bad idea. (Catechism, 1723, 2112–2114, 2289, 2424)

That said, I live on Earth, so enlightened self-interest dictates a reasoned concern over this planet’s condition. On top of that, we’re this world’s stewards, responsible for managing the place: using this world’s resources wisely, showing concern for our neighbors and future generations. (Catechism, 339, 952, 2402–2405, 2415, 2456)

I talked about sane environmentalism last month. (August 12, 2016)

4 ‘Silly season:’ the later part of summer, when newsworthy events are generally few and far between; in the English-speaking northern hemisphere of Earth, anyway.

5 Excerpt from Dr. Miller’s op-ed:

“…The implications of realizing we’re not alone in the universe would go something like this, I think:

“1. Secrecy, for as long as it could be maintained. People blissfully unaware, and no change to our lives.

“2. Authoritarianism. An almost war footing for governments as they try to work through implications. Similar impact on people’s liberties as being at war, as resources are diverted to figure out what it means, and others take advantage of that diversion of resources.

“3. Religious polarization. The religious spectrum polarized more dramatically towards the poles. Not a complete shift, but more evangelicals, and more hard-core atheists. The people in those categories become more extreme; those in between are annoyed by them.

“4. Societal shift. A shift in sciences, resurgence for evaluating cultural differences, language, humanities, and communications. Other ‘hard’ sciences get reduced. Again, this affects those in those disciplines.

“Ah, but that wasn’t the question. For the average person, I think life would trundle on. It’s like a building toppling over next door. You stop, you stare, you’re amazed. Then you move on. Maybe your life is a little different, a little less convenient, but a million details are still the same….”

Love, Mercy, and 9/11

Posted on September 11, 2016 by Brian H. Gill

Airliners were flown into New York City’s World Trade Center and the Pentagon 15 years ago today, killing nearly 3,000 folks whose chief offense had been living in an American city and going to work Tuesday morning.

The 19 immediately responsible died with their victims. They were waging Osama bin Laden’s religious war against the United States.

Osama bin Laden is dead now, and so are a great many others: perpetrators and victims; Christians, Muslims, and folks who were simply in the wrong place at the wrong time.

On top of that, about 1,800,000 folks were stopped last year, while trying to get into Europe. Some may have had ulterior motives; but most were trying to stay alive, fleeing because their former homes had become a war zone.

It’s the biggest problem of that sort Europe’s had since the 1940s. Quite a few folks are upset: partly because most of the refugees hadn’t had opportunities to fill out all their paperwork before entering Europe.

The “European migrant crisis” is anything but simple.1

My family and I aren’t as far-removed from the situation as it might seem.

The regional economy here in central Minnesota includes a fair number of jobs that require no language skills or previous experience: so quite a few immigrants find their way here, despite the climate.

How I feel about that involves stories about sheep, a lost coin, and a playboy.

Living the High Life – – –

Today’s Gospel reading is a longer version of what we heard back on March 6.2 Both start in the same place:

“1 The tax collectors and sinners were all drawing near to listen to him,

“but the Pharisees and scribes began to complain, saying, ‘This man welcomes sinners and eats with them.’

“So to them he addressed this parable.”
(Luke 15:1–3)

The rest of Luke 15:1–32 is the familiar parable of the lost sheep, coin, and son; three mini-stories with the same message.

The ‘prodigal son’ story has inspired a mess of creative works, including a painting by Rembrandt, an oratorio by Arthur Sullivan, a movie starring Lana Turner, and a track on Kid Rock’s The Polyfuze Method album.

Yet another — mercifully short — retelling shouldn’t hurt. Feel free to skip over the next few paragraphs.

The younger son asks for his share of the family fortune, gets it, moves to “a distant country” and lives the high life.

Luke doesn’t say, but I figure the sons are probably ‘college age:’ 18-25, which you couldn’t pay me to go through again.3

– – – Until the Money Runs Out

Then his money runs out and a famine hits.

The good news is that he doesn’t starve. The not-so-good news is that the only position available is swineherd: low status, bad work environment, and worse pay.

That’s when he has a eureka moment:

“Coming to his senses he thought, ‘How many of my father’s hired workers have more than enough food to eat, but here am I, dying from hunger.

“I shall get up and go to my father and I shall say to him, “Father, I have sinned against heaven and against you.

“I no longer deserve to be called your son; treat me as you would treat one of your hired workers.” ‘ ”
(Luke 15:17–19)

You know the rest: the father runs to greet him, orders an extravagant feast, and tries to calm down his older son — who’s understandably piqued. (Luke 15:31–Luke 15:32)

Before talking about sinners, immigrants, and mercy, I’d better talk about sin.

Sin, Sinners, and Me

I sin when I decide that I’ll do something I know is bad for myself, or others: or decide to not do something I should. It’s an offense against reason, truth, and God. (Catechism of the Catholic Church, 1849–1864)

That happens whenever I don’t love God, love my neighbors, see everybody as my neighbor, and treat others as I want to be treated. (Matthew 5:43–44, 7:12, 22:36–40, Mark 12:28–31; Luke 6:31 10:25–27, 29–37)

Happily, acting like the post-swineherd prodigal son is an option as long as I’m alive. (Catechism, 976–983, 1442–1470, 1021, 1988)

“Love” isn’t “approval,” and I’ll get back to that.

Maybe it’d be simpler if humanity was split into the “righteous” and “sinners:” but that’s not how it is.

I’m a sinner, since I occasionally offend reason, truth, and God.

That doesn’t mean God made a horrible mistake when creating this world and me.

The universe is basically good, and so is every person, including you and me — basically. (Genesis 1:31; Catechism, 31, 299, 355)

Something obviously went wrong, but it wasn’t a design flaw.

We are rational creatures who can decide what we do, like angels. Unlike angels, we are also material creatures: spiritual beings with a body made from the stuff of this world. (Catechism, 311, 325–348, 1704, 1730–1731)

Having a body isn’t the problem, by the way. Satan, like all angels, has no body. That didn’t stop Satan and other angels from saying “no” to God. (Catechism, 385–395)

Since I’m a Catholic, I see original sin as the lasting consequences of a really bad decision.4

Love and Moderation

I also must see human beings as people: all human beings.

Genesis 1:27 says we’re made “in the divine image.”

We are rational and therefore like God, made in the image and likeness of God; created with free will, masters over our actions. (Catechism, 1730–1825)

All humans are people, with equal dignity: no matter where we are, who we are, or how we act. (Catechism, 360, 1700–1706, 1932–1933, 1935)

That includes the 9/11 hijackers.

Thinking that they’re people, with the dignity due to any human being, doesn’t mean I must approve of what they did.

They deliberately killed a few thousand folks, including themselves. They apparently agreed with Osama bin Laden, that Americans should be killed because our government wasn’t doing what bin Laden wanted.

I don’t approve of everything my government does: but killing office workers isn’t a reasonable response.

Murder, deliberately killing an innocent person, is wrong because human life is sacred. (Catechism, 2258, 2268–2283)

Killing my neighbor is wrong; even if I don’t like the color he painted his house, his political views, or how he worships.

Okay, let’s say killing innocent people is wrong: but what about not-innocent people?

Let’s say my neighbor goes nuts and tries to kill me and my family. Loving my neighbor doesn’t extend to passively accepting death at my neighbor’s hands.

I’m allowed to avoid or resist the attack; using the least force necessary. The same principle applies to groups of people. (2263–2267, 2307–2317)

“Love toward oneself remains a fundamental principle of morality. Therefore it is legitimate to insist on respect for one’s own right to life. Someone who defends his life is not guilty of murder even if he is forced to deal his aggressor a lethal blow:

If a man in self-defense uses more than necessary violence, it will be unlawful: whereas if he repels force with moderation, his defense will be lawful. … Nor is it necessary for salvation that a man omit the act of moderate self-defense to avoid killing the other man, since one is bound to take more care of one’s own life than of another’s.66“

(Catechism, 2264)

Like I said, the basics are simple: I must love God, my neighbor, and myself.

Applying those simple principles: that’s where it gets tricky, which gets me back refugees, immigrants, and other “strangers.”

America’s consumer spending per household is the second-highest in the world. This is not a poor country.

I think so many folks try to move here because we’re still one of the better places to raise a family.

I don’t see immigrants as a problem, partly because all of my ancestors are immigrants.

Even if I did, I couldn’t: or shouldn’t. Not if I’m going to take my faith seriously. (Catechism, 2241)

Besides: the repentant son and the loving father in that parable seem like better role models than the older brother.

The idea of treating folks who moved into the neighborhood from another country the same way we treat old neighbors isn’t particularly new. It’s also what we’re supposed to do. (Exodus 23:9; Leviticus 19:33–34; Matthew 25:35)

Maybe that sounds nice, but why should I care?

Backing up a bit, I follow Jesus — who set a very high standard; dying for my sake, and yours.5

The Best News Ever

God loves us, and wants to adopt us. All of us. (Matthew 5:45; John 1:12–14, 3:17; Romans 8:14–17; Peter 1:3–4; Catechism, 1, 27–30, 52, 1825, 1996)

This is the best news humanity’s ever had.

However, accepting God’s mercy is an option. We can say “no” and walk away. Each of us has free will. (Catechism, 311, 396, 1021–1022, 1704)

I decided that accepting God’s offer made sense, so acting like a member if the family seems reasonable: to me, anyway.

Admitting my faults — and forgiving others — is vital. (Catechism, 1847, 2840)

More about forgiveness and alternatives:

“11 If you forgive others their transgressions, your heavenly Father will forgive you.

“But if you do not forgive others, neither will your Father forgive your transgressions.”
(Matthew 6:14–15)

“1 2 ‘Stop judging, that you may not be judged.

“For as you judge, so will you be judged, and the measure with which you measure will be measured out to you.”
(Matthew 7:1–2)

“1 Therefore, you are without excuse, every one of you who passes judgment. 2 For by the standard by which you judge another you condemn yourself, since you, the judge, do the very same things. … There is no partiality with God.”
(Romans 2:1–11)

Forgiving others and showing mercy does not mean being stupid.

We can decide that what someone does is a “grave offense,” responding with charity and justice. (Catechism, 1861, 1928–1942, 2197–2246, 2401)

And we must trust God’s justice and mercy for what happens to them — and each of us — in the long run. (Catechism, 1861, 1928–1942)

More of my take on acting like God matters:

1 A little background:

2 Gospel reading for March 6, 2016; the fourth Sunday in Lent:

And see:

3 The 18-25 demographic, a little background:

4 Definitions:

“CONCUPISCENCE: Human appetites or desires which remain disordered due to the temporal consequences of original sin, which remain even after Baptism, and which produce an inclination to sin (1264, 1426, 2515).

“ORIGINAL SIN: The sin by which the first human beings disobeyed the commandment of God, choosing to follow their own will rather than God’s will. As a consequence they lost the grace of original holiness, and became subject to the law of death; sin became universally present in the world. Besides the personal sin of Adam and Eve, original sin describes the fallen state of human nature which affects every person born into the world, and from which Christ, the ‘new Adam,’ came to redeem us (396–412).

“SIN: An offense against God as well as a fault against reason, truth, and right conscience. Sin is a deliberate thought, word, deed, or omission contrary to the eternal law of God. In judging the gravity of sin, it is customary to distinguish between mortal and venial sins (1849, 1853, 1854).”
(Catechism of the Catholic Church, Glossary)

It’s a big deal:

“But I say to you, love your enemies, and pray for those who persecute you,

“that you may be children of your heavenly Father, for he makes his sun rise on the bad and the good, and causes rain to fall on the just and the unjust.”
(Matthew 5:44–45)

“And the king will say to them in reply, ‘Amen, I say to you, whatever you did for one of these least brothers of mine, you did for me.’ ”
(Matthew 25:40)

“Indeed, if, while we were enemies, we were reconciled to God through the death of his Son, how much more, once reconciled, will we be saved by his life.”
(Romans 5:10)

Philae, Jupiter, and Life

Posted on September 9, 2016 by Brian H. Gill

Scientists spotted Philae, the European Space Agency’s spacecraft that crash-landed on 67P/Churyumov-Gerasimenko in 2014: which will help them make sense of data sent back while the probe still functioned.

Other scientists think they’ve worked out where carbon near Earth’s surface came from, and the Juno orbiter has been sending pictures of the giant planet.

Vitalism, Mad Scientists, and Space Vampires


(Frame from Fritz Lang’s “Metropolis,” via Netflix, used w/o permission.)
(Jump-starting Rotwang’s Maschinenmensch in “Metropolis.”)

“Vitalism is a discredited scientific hypothesis that ‘living organisms are fundamentally different from non-living entities because they contain some non-physical element or are governed by different principles than are inanimate things’. Where vitalism explicitly invokes a vital principle, that element is often referred to as the ‘vital spark’, ‘energy’ or ‘élan vital‘, which some equate with the soul….”
(Wikipedia, Vitalism)

All that’s left of vitalism these days are pop-psychology and literary references to the four humors: sanguine, choleric, melancholic, and phlegmatic, movies like Fritz Lang’s “Metropolis“— and “Lifeforce,” a rousing yarn involving Halley’s Comet and space vampires.

Vitalism made more sense back when philosophy, religion, and systematic study of nature weren’t nearly as distinct from each other as they are now.

Our definitions of what’s organic and what’s not seem somewhat arbitrary in part because today’s sciences of physics and chemistry were getting started while vitalism was still taken seriously.

Some researchers pointed out that chemical transformations involving non-living substances are reversible: but chemical transformations permanently change “organic” matter. They’re right, in a way. It’s impossible to un-cook an egg.

Then Friedrich Wöhler synthesized urea. That was in 1828. John Scott Haldane (1860-1936) wasn’t, strictly speaking, a vitalist; but he wasn’t, I gather, a mechanist, either.

I’m a Catholic, so I must believe that natural processes are created by God, that the universe is beautiful, and follows knowable physical laws. (Catechism of the Catholic Church, 32)

Because physical phenomena reflect some facet of the Creator’s truth, according to their nature, we can learn something about God by studying them. (Catechism, 282–289, 306–308)

I was going somewhere with this. Let’s see: vitalism, organic, vital spark, “Lifeforce.” Right.

The search for extraterrestrial life might be a whole lot easier if we could scan the sky for concentrations of élan vital. As it is, defining what we’re looking for has become a tad more difficult as we learn more about life and the universe.

Life and using our Brains

Defining “life” seems pretty easy. We can tell if something’s alive or not just by looking. For example, I’m alive: but a lump of rock on my desk isn’t.

It’s simple: until we start thinking about exactly how we define the difference between “living” and “not living.” Over the millennia, folks have come up with some pretty good definitions. I’ll focus on two:

  • Vitalism
    • Living things contain a life-force
    • Non-living things don’t
  • Biology
    • Homeostasis: Regulating and maintaining constant internal conditions
    • Organization: Made of one or more cells
    • Metabolism: Transforming energy by converting chemicals and energy into cellular components
    • Growth: Increasing the size of each internal component
    • Adaptation: Changing slowly in response to the environment
    • Response to stimuli: Changing quickly in response to the environment
    • Reproduction: Producing new individual organisms

    (Source: Wikipedia)

I like the ‘biology’ definition, as given in that Wikipedia page, partly because it doesn’t insist that “life” must be “organic.” Scientists have come up with several hypothetical types of biochemistry, including that science fiction standby, silicone biochemistry.

Now, my usual spiel about using the brains God gave us being okay.

I see no problem with studying this vast and ancient creation: even, make that particularly if, we have to revise some of our assumptions in the process.

Science and technology are tools, using them is part of being human. It’s not all there is to life, and that’s another topic. (Catechism, 1723, 2292–2296)

We’re created by God, designed with a thirst for truth and for God. We’re made from the stuff of this world. We’re also made “in the image of God,” creatures who are matter and spirit. Using our senses and reason, we can observe the world’s order and beauty: learning something of God in the process. (Genesis 1:26, 2:7; Catechism, 27, 31–35, 282–289, 355–361)

1. Philae: Found


(From ESA/Rosetta/MPS for OSIRIS Team, via BBC News, used w/o permission.)
(“Hello, old friend: Philae (near top right, in darkness) comes back into view”
(BBC News))

“Philae: Lost comet lander is found”
Jonathan Amos, BBC News (September 5, 2016)

“Europe’s comet lander Philae has been found.

“The little robot is visible in new images downloaded from the Rosetta probe in orbit around the icy dirt-ball 67P/Churyumov-Gerasimenko.

“European Space Agency (Esa) officials say there is no doubt about the identification – ‘it’s as clear as day’, one told the BBC.

“Philae was dropped on to the comet by Rosetta in 2014 but fell silent 60 hours later when its battery ran flat….”

The Philae lander was supposed to sample Churyumov-Gerasimenko’s surface, and drill for subsurface analysis. Quite a bit of the planned research was possible, despite the awkward landing.

Philae was designed to recharge its secondary battery during daylight hours. Fetching up as it did, lying on its side in a steep ditch, that didn’t happen. The lander’s solar cells had sunlight for only 90 minutes during each of the comet’s 12.4-hour days.

We got some exciting results anyway.

The Ptolemy and COSAC (Cometary Sampling and Composition experiment) experiments found sixteen organic compounds were detected, four of which were seen for the first time on a comet: acetamide, acetone, methyl isocyanate and propionaldehyde.

Don’t bother trying to remember those names, there will not be a test on this.

“Organic Chemistry Throughout the Universe”


(From ESA/Rosetta/MPS for OSIRIS Team/NavCam, via BBC News, used w/o permission.)
(“The top inset shows the position on the comet; the bottom inset is a blow-up of Philae”
(BBC News))

“…Although it relayed pictures and data about its location to Earth, the lander’s actual resting place was a mystery.

“It was assumed Philae had bounced into a dark ditch on touchdown – an analysis now borne out by the latest pictures, which were acquired from a distance of 2.7km from the duck-shaped icy body….”
(Jonathan Amos, BBC News)

Those compounds with long names, like methyl isocyanate and propionaldehyde, are organic, but “organic” isn’t “alive.”

That didn’t keep us from having a little excitement last year:

We may eventually learn that Chandra Wickramasinghe, a retired professor, and Max Willis were right, but I think that’s unlikely.

What we’ve been finding is a universe permeated with life’s building blocks. As the UK Astrobiology Centre’s director, Professor Charles Cockell, said last year — the Rosetta/Philae mission results were “very significant:”

“…’It gives us better ideas about how those building blocks of life may have formed and where they may have come from.

“‘It confirms there is organic chemistry throughout the universe, that carbon-containing compounds, some of which are very complex, could be being formed on comets in our solar system.’

Prof Mark McCaughrean, the European Space Agency’s senior science advisor, told BBC News: ‘Imagine you want to build a house and you go to a forest, where there are trees, mud and rocks. You could make a house out of that, but it would be hard work.

“‘Well, we’ve now discovered the comet is more like a hardware shop – lots of pre-made building blocks, like door frames, bricks etc. It gives you a head start.

“‘One of the big questions, though, is this material made on the comet? Or is it made first in space and then incorporated into the comet? We don’t know the answer to that yet.’…”
(David Shukman, BBC News (July 30, 2015))

We still don’t know where those organic compounds came from: but we’re learning.

A Good Question, and Looking Ahead

“…The images from Rosetta’s high-resolution Osiris camera were downlinked to Earth late on Sunday night, and have only just been processed.

“Philae is seen wedged against a large over-hang. Its 1m-wide box shape and legs are unmistakable, however.

“Rosetta had previously surveyed this location – dubbed Abydos – without success.

“‘Candidate detections’ were made but none were very convincing.

“The difference today is a closer-in perspective and a change in the seasons on the comet, which means the hiding place is now better illuminated….”
(Jonathan Amos, BBC News)

Victor S E Moubarak asked “How are they ever going to bring back all this stuff they leave up there?” — which is a good question.

My guess is that eventually salvage crews, or maybe archeologists, will get around to picking up Philae and other more-or-less intact hardware. That’ll have to wait until we have much more efficient off-Earth transportation tech, though.

A more immediate issue is what to do about the growing accumulation of debris orbiting Earth: and that’s yet another topic.

In case you haven’t had enough of Philae and comets yet, I put images from the lander and a resource link list near the end of this post.1

2. Earth’s Carbon and Planetary Collisions

(“The team suggests Earth merged with a Mercury-like protoplanet”

“Planet smash-up ‘brought carbon to Earth’ ”
BBC News (September 5, 2016)

“Much of Earth’s life-giving carbon could have been delivered in a planetary collision about 4.4 billion years ago, a theory suggests.

“Carbon is the key ingredient for all life on our planet.

“But how Earth acquired its ‘volatile elements’ – which have low boiling points – such as carbon and sulphur remains a subject of some debate.

“A team now argues that a collision between Earth and an embryonic planet like Mercury could provide the answer….”

This idea isn’t nearly as unlikely as it might seem. Today’s Solar System is a comparatively tidy place, with most planets in nearly-circular orbits at comfortably-spaced intervals. It wasn’t always that way.

The cosmic scale of this creation has become increasingly hard to ignore, and I’ve talked about that before. (August 28, 2016)

We’re pretty sure that the Solar System, Earth included, started as a thick spot in a whacking great molecular cloud like the Keyhole Nebula. I put another resource link list near the end of this post.2

It’s a near-certainty that other stars formed from the same cloud, but we haven’t found the ‘Solar siblings.’ Not as of 2010, at any rate, and that’s yet again another topic.

“The Dynamics Could Work”


(From Rajdeep Dasgupta, via BBC News, used w/o permission.)

“…According to a widely accepted idea called the Late Veneer Hypothesis, Earth formed from material that was largely devoid of volatiles. These elements, such as carbon, sulphur, nitrogen and hydrogen, were added later on by space rocks after Earth’s core had finished forming.

“‘Any of those elements that fell to Earth in meteorites and comets more than about 100 million years after the Solar System formed could have avoided the intense heat of the magma ocean that covered Earth up to that point,’ said Yuan Li, from the Guangzhou Institute of Geochemistry at the Chinese Academy of Sciences.

“‘The problem with that idea is that while it can account for the abundance of many of these elements, there are no known meteorites that would produce the ratio of volatile elements in the silicate portion of our planet.’…”
(BBC News)

Where was I? Solar System origins, cosmic scale, planetary collisions. Right. I wouldn’t worry about Mercury hitting Venus, by the way. In the sort term, the next several million years in this case, their orbits should stay pretty much where they are now.

How concerned our descendants get, when and if the collision is imminent, may depend on where the debris is likely to go; and whether we’ve terraformed Venus by then. And that’s still another topic.

Like I said, given what we’re learning about the early Solar System, this idea isn’t all that unlikely.

One of the more plausible explanations for our moon’s origin is that our planet and another one, about the size of Mars, collided some 20,000,000 to 100,000,000 years after the planets formed.

What’s attractive about this hypothesis is that — I’ll let one of the scientists explain it:

“…’Because it’s a massive body, the dynamics could work in a way that the core of that planet would go directly to the core of our planet, and the carbon-rich mantle would mix with Earth’s mantle,’ said Dr Dasgupta.”

3. Pictures from Jupiter

(“Juno took this picture as it flew over the north pole, from a distance of 195,000km”
(BBC News))

“Juno probe returns close-up Jupiter pictures”
Jonathan Amos, BBC News (September 2, 2016)

“The US space agency (Nasa) has released spectacular new images of Jupiter acquired by its Juno probe.

“The pictures show the swirling clouds of the gas giant at both its poles – views that no previous mission has managed to acquire in such detail.

“Juno captured the data last weekend as it made its first close approach to the planet since going into orbit in July.

“The flyby took the spacecraft just 4,200km above Jupiter’s multi-coloured atmosphere….”

I talked about Juno and Jupiter when the spacecraft settled into Jupiter orbit. (July 29, 2016)

Recapping, data from Juno’s instruments should tell scientists how much of Jupiter is water, and help them map the planet’s magnetic and gravitational fields.

That’s a big deal for folks who wonder how Jupiter, and the Solar System, formed; and what powers Jupiter’s magnetic field.

They’ll also be measuring orbital frame-dragging around Jupiter. That’s what happens when moving concentrations of mass-energy drag space-time along with them. It’s also called Lense-Thirring precession, and again: there will not be a test on this.

Jovian Poles


(From NASA/JPL-Caltech/SwRI/MSSS, via BBC News, used w/o permission.)
(“South Pole: Such views have never before been acquired at Jupiter”
(BBC News))

“…The 6MB of data downlinked to Earth from the encounter is still being analysed, but principal investigator Scott Bolton said new things were already obvious.

“‘First glimpse of Jupiter’s north pole, and it looks like nothing we have seen or imagined before. It’s bluer in colour up there than other parts of the planet, and there are a lot of storms,’ the Southwest Research Institute scientist explained in a Nasa statement.

“‘There is no sign of the latitudinal bands or zones and belts that we are used to – this image is hardly recognisable as Jupiter.

“‘We’re seeing signs that the clouds have shadows, possibly indicating that the clouds are at a higher altitude than other features.’…”
(Jonathan Amos, BBC News)

I’ll admit that Jupiter’s south pole looks pretty much like the planet’s north pole. That’s probably not such a big surprise. Neither, I suppose, are the differences between Jupiter’s equatorial regions and its poles.

Juno, Jupiter, and Looking for Life


(From NASA/JPL-Caltech/SwRI/MSSS, via BBC News, used w/o permission.)
(“The southern hemisphere of Jupiter pictured from a distance of 38,000km”
(BBC News))

“…The spacecraft is currently flying on an ellipse around Jupiter that takes 53 days to complete. Its next close approach is due on 19 October, when the probe will fire its main engine to tighten the circuit to just 14 days.

“This configuration will then be held until February 2018 when the spacecraft will be commanded to make a destructive dive into Jupiter’s atmosphere….”
(Jonathan Amos, BBC News)

Juno is one probe we won’t be recovering, and for good reason. Europa, one of Jupiter’s moons, almost certainly has a substantial ocean under its ice. That, the moon’s chemistry, and energy from tidal flexing, make it one of the most likely places for extraterrestrial life in the Solar System.

If, make that when, we land a thoroughly-sterilized probe on Europa, we’ll want to be reasonably certain that any terrestrial organisms we find there didn’t hitch a ride on a recent spacecraft.

Inevitably, I put links near the end of this post.3

Terrestrial life on Europa wouldn’t prove that alien astronauts were here. We’ve been learning that spatter from large impacts could transfer living microcritters from one planet to another. Maybe:

How likely that is — yeah, that’s another topic.
