There’s a good piece by Seth Shostak over at Space.com about the possible motivations an extra-terrestrial race might have for visiting our pale blue dot. (Shostak is one of the principals of the SETI Institute, and knows whereof he speaks when he addresses these kinds of issues.) First, he dismisses the usual SF plot devices of an alien race wanting our turf, our resources, or even our bodies:
Taking our cue from Tinseltown, I note that most cineplex sentients come to Earth either to solve some sort of ugly reproductive crisis or simply to take over the planet. The former doesn’t make any sense whatsoever. You can’t breed with creatures at the zoo, despite the fact that most of the base pairs in the inmates’ DNA are identical to yours (note that this is a biological incompatibility, and not just zoo regulations). The aliens, needless to say, will have a different biochemistry, and probably no DNA at all. Forget, if you can, the breeding experiments.
Taking over the planet would only make sense if there were something really special about our world. The best guess of the exoplanet specialists is that the number of Earth-size planets in our galaxy exceeds tens of billions. That doesn’t sound like our hunk of real estate is terribly privileged.
They won’t come here to mine our minerals, either. The entire universe is built of the same stuff, and while the solar system has a higher percentage of heavy elements than found in many stellar realms, it turns out that this is precisely the condition that seems to foster planet formation. In other words, ET’s own solar system will be similarly blessed with these useful materials. So why would they come here and incur multi-light-year transport charges?
Why, indeed? These various issues are ones which are discussed in the course of speculation about the alien artifact discovered in Communion of Dreams. And while I never actually reveal the motivations that aliens might have for having left the artifact on Titan in my novel, I do have thoughts on the subject (which might come out in a future sequel to Communion.)
Be that as it may, Shostak does go on to make a pretty good argument that if indeed there are a large number of technological civilizations out there, that they may just not consider us worth the trouble of contacting/visiting. Again, from the article:
Then again, there’s that last point: they just want to learn more about us. Well, perhaps so. Maybe that’s really what’s interesting about Homo sapiens. Not grabbing our habitat, saving our souls (or our environment), or subverting our industrial output — but assaying our culture. I’m willing to consider that even very advanced beings might find our culture mildly worthy of study.
Keep in mind that if they’re near enough to find us, that implies that there are many, many galactic societies (otherwise the distances between any two of them will be enormous). If there are lots of them, then we’re just another entry in a big book. Once again, not all that special. Kind of like another weird fish found in the Atlantic. I don’t expect mammoth expeditions to be sent our way.
It is a good point. I would counter, however, that we have seen plenty of evidence in our own history of people going to enormous trouble to bother to learn about seemingly trivial things. One only has to look at the difficulties encountered in sea-faring during the time of the great naturalists – people were willing to go to great expense, to risk great hardship and a fair chance of death just to add another entry into the botanical texts or to discover a new species. Even today we mount insanely expensive expeditions into the deep ocean just to expand our knowledge.
We have no evidence of extra-terrestrial life, let alone advance civilizations. Yet I think that you can make a fair case that any space-faring race which may exist must have some degree of curiosity – and that curiosity may alone be reason enough to come check out the new kids on the block, whatever the hurdles or cost.

Gah. I am either having a relapse of the very stubborn flu that had me laid low last month, or am fighting some new bug with similar (yet still considerably less severe) symptoms. This is highly annoying.
So, I’m about to go take a nap. But first a couple of quick notes, and then a bit from Phil Plait’s blog about a recent discovery that is very exciting.
Note one: downloads of the .pdf of Communion of Dreams have crossed 8,200 and downloads of the audio version continue to climb as well. That’s exciting.
Note two: heard nothing yet from the agent I mentioned contacting the other day. No surprise – I expect that it will take a month or so to hear from them. But I needed something else to note.
Now, about the news from space . . .
I have written previously about the Cassini probe’s 10 year mission to Saturn, and how there have been a lot of great images and information coming back to scientists about that planet and its moons. Information that helps to confirm what we knew when I was first writing Communion (since most of the action of the book takes place on and around Titan.) But there is news which would potentially require me to revise the novel slightly – not about Titan, but about its sibling Enceladus. You may have heard something about this, but I’ll go to the Bad Astro Boy himself for the news:
Life’s cauldron may be bubbling underneath Enceladus
A few days ago I wrote about how the Cassini Saturn probe dove through water ice plumes erupting from the surface of the icy moon Enceladus. The pictures were incredible, but it may very well be that the other detectors got the big payoff.
They detected organic compounds in the plumes.
Now remember, organic molecules don’t necessarily mean life. What Cassini detected were heavy carbon-based molecules, including many that are the building blocks for making things like amino acids and other compounds necessary for life as we know it.
Edited to add: Carolyn Porco, imaging team leader for Cassini, says:
[…] it is now unambiguous that the jets emerging from the south polar fractures contain organic materials heavier than simple methane — acetylene, hydrogen cyanide, formaldehyde, propane, etc. — making the sub-surface sources of Enceladus’ dramatic geological activity beyond doubt rich in astrobiologically interesting materials.
Whoa. I mean, *whoa* . Seriously. It ain’t life, nor even proof of life – but it is *damned exciting*.
Now, a nap. All this excitement makes me tired.

What is it with big corporations turning to space-related gimmicks in order to promote their products?
Last week Phil Plait on his Bad Astronomy site did a post about a beer maker’s ‘plan’ to advertise using a laser to shine their logo onto the Moon. (The second comment in that thread remembered me, and I also posted a comment about my Paint the Moon project from years back when I was writing Communion of Dreams.) It’s really just an advertising trick – they’re not seriously going to try it from what I can tell. So, like my communal fantasy art project, no real harm nor foul.
More worrying is this bit via redOrbit:
Doritos to Broadcast First Ad into Space
The campaign to broadcast the first ever advert into space is launched today (Friday March 7) with University of Leicester space scientists playing a key part in the process.
The British public is being asked to shoot a 30-second ad about what they perceive life on earth to be as part of Doritos ‘You Make It, We Play It’ user-generated-content campaign. The winning advert in the competition will be beamed past the earth’s atmosphere, beyond our solar system and into the Universe, to anyone ‘out there’ that may be watching. The winning ad will also be broadcast on terrestrial TV.
Catch that bit about scientists from the University of Leicester being involved? Well, some of the facts reported in the long article strike me as being a bit dodgy, but there is little doubt that indeed the scientists have signed on, for their own reasons. From the article again:
Dr Darren Wright of the University of Leicester Department of Physics and Astronomy said: “The Radio and Space Plasma Physics Group and Department of Physics and Astronomy as a whole at the University of Leicester has a very high international profile in the area of Space Physics.
“An important part of this project is that it provides an additional component to the Physics and Astronomy Department’s ever increasing outreach program. The ad to be transmitted will be created by the public following a national competition thus increasing public awareness of space activities.
“The launch of this project as we embark on National Science and Engineering Week- with a range of activities taking place at the University of Leicester- is timely, and adds impetus to our efforts to interest people in science.
“The University is particularly committed to outreach programs along with the National Space Centre – the brainchild of the University of Leicester – and engaged in a number of programs with the wider public.”
(I could find nothing on the UL site about this, but it seems to not have been updated that recently.)
So, in order to better promote their university and outreach program, they are willing to join in on this gimmick with Doritos. The Doritos UK site (warning – it’s one of those Flash-heavy sites that assumes you have at least a gig of RAM running) even has this confirmation:
We’ll even beam the winning advert into space just for the hell of it. But if passing aliens pick up the message and invade Earth looking for tasty snacks, don’t blame us.
Hahaha! See, it’s all just another joke, like the Moon/Beer Sign! Hilarious!
The problem is, there are real issues to be considered in taking an active role in broadcasting messages out in space, as I noted in this post from last June:
And I guess that’s where I come down on the question of whether or not we should be broadcasting “contact” signals out into the cosmos, in the hope of connecting with some other intelligent life.
Just about every major science fiction author has dealt with the question of alien contact at some point or another. Sometimes it is handled with an assumption of happy-happy E.T. helping us out, being part of the big brotherhood of intelligent species. Sometimes it is having us be lunch. Sometimes we’re the bad guys, enslaving other races or having them for lunch.
I tend to agree with Carl Sagan’s position that we’re unlikely to be at anything resembling technological parity with another race (and this is the premise of Communion of Dreams). And I tend to agree with those who advocate a certain caution in making our presence known in the universe. Via MeFi, there’s a very good article on this very topic in The Independent by Dr. David Whitehouse, formerly the BBC Science Editor and a respected astronomer, that I heartily recommend. An excerpt:
The fact is, and this should have been obvious to all, that we do not know what any extraterrestrials might be like – and hoping that they might be friendly, evolved enough to be wise and beyond violence, is an assumption upon which we could be betting our entire existence. When I was a young scientist 20 years ago at Jodrell Bank, the observatory in Cheshire, I asked Sir Bernard Lovell, founder of Jodrell Bank and pioneering radio astronomer, about it. He had thought about it often, he said, and replied: “It’s an assumption that they will be friendly – a dangerous assumption.”
And Lovell’s opinion is still echoed today by the leading scientists in the field. Physicist Freeman Dyson, of the Institute for Advanced Study in Princeton, has been for decades one of the deepest thinkers on such issues. He insists that we should not assume anything about aliens. “It is unscientific to impute to remote intelligences wisdom and serenity, just as it is to impute to them irrational and murderous impulses,” he says. ” We must be prepared for either possibility.”
The Nobel Prize-winning American biologist George Wald takes the same view: he could think of no nightmare so terrifying as establishing communication with a superior technology in outer space. The late Carl Sagan, the American astronomer who died a decade ago, also worried about so-called “First Contact”. He recommended that we, the newest children in a strange and uncertain cosmos, should listen quietly for a long time, patiently learning about the universe and comparing notes. He said there is no chance that two galactic civilisations will interact at the same level. In any confrontation, one will always dominate the other.
Sure, our broadcasts have been leaking out into space for a hundred years. But using a sophisticated system such as proposed for this absurd commercial is another story – there may be almost zero chance that such a signal could ever be picked up (even if there is intelligent extra-terrestrial life). But it is still a foolish risk. It’d be terribly embarrassing to have some other civilization get our snack food commercial, let alone to have them show up and decide that we tasted even better than the chips.

Phil Plait, the Bad Astronomer, has been at the American Astronomical Society meeting in Austen most of this week, and has had a wonderful series of posts about the meeting. He just posted the final one this morning (though there will undoubtedly be follow-up posts once he is home as sorted things out). You can find the whole series on his blog.

Not exactly related to Communion aside from “tholins”, but I thought you’d be interested.
It is interesting to see that these complex organic molecules have been found in such abundance. The term tholin was coined by Carl Sagan in his early writings about Titan, and I discuss the material extensively in Communion of Dreams (if you haven’t read it -and if not, why not?).
~~~ Thanks, Jacob!

Speaking of notes, I got this nice one from Carl:
I just wanted to say that I’ve truly enjoyed your posts since you’ve joined UTI and your novel is top-notch. I’m not a big sci-fi fan, but your characters and description held me all the way through.

A brief update on my MIL’s condition: the visit from the hospice nurse on Thursday confirmed what we’d seen this week – continued deterioration. Her BP is very low, pulse weak, and heart rate very high (all worse than they were the previous week), and her lungs have diminished capacity and evidence of fluid. Once again we have tweaked her meds and treatment procedures, but this is mostly just an effort to keep her as comfortable as possible. I think part of the exhaustion my wife and I feel is just ongoing anticipation.
I’ll keep you posted.

I commented via email to a close friend yesterday about the persistent fever my MIL has been running, 2 to 2.5 degrees above her normal. We’d seen fevers come and go for the last several months, but this one seems to have settled in for a while. I got back this:
Any particular reason for it, or is she just being like a star that’s going into its final flameout?
* * * * * * * * * * * * *
Like my friend, I grew up after the basic mechanisms of stellar evolution were pretty well understood. What I learned long ago, and seems to still hold basically true is this: stars in the main sequence will develop, go through an initial process of fusion converting hydrogen into helium, and then will evolve one of several ways depending upon initial mass. Small to medium-sized stars will make it into the helium fusion phase (primarily producing oxygen, nitrogen and carbon), before burning out and eventually becoming a white dwarf. Larger stars can go on to greatness, however, and in the sequence of their lives (including supernova) produce all the natural elements we know in a process known as nucleosynthesis. Either way, massive amounts of material are stripped away from the star and disseminated out into the universe through explosion, solar wind, and other similar mechanisms.

What is oldest, lasts longest. That is the basic equation to understanding Alzheimer’s.
Generalizing: First, the person with Alzheimer’s will lose the ability to learn new skills. Then the most recent memories will slip, and each succeeding layer of memory acquired in their life will melt away. Metaphorically, they are being deconstructed – like some great skyscraper which is slowly dismantled from the top down, floor by floor. Compare this to other diseases and injuries, which are more like an implosion of consciousness, collapsing in on itself all at once.
Because of the way the disease progresses, layer after layer of experience and memory being peeled away, the patient regresses through life, becoming once again a child in many ways. This is likely the origin of the notion that the elderly experience a “second childhood” with dementia.

Looking back over the last three or four months, it has been a difficult time. I read the posts I’ve made here on the topic, and am frankly surprised that things have been as bad as they have been for as long as they have been. No wonder I am exhausted, even with the extra help we’re getting thanks to Hospice.
Yesterday was a bad day. Whether because of the fever, or just her deteriorating condition, my MIL was really in a state of constant confusion about everything starting first thing in the morning. Nothing was easy, and she needed near-constant reassurance and supervision. Then, shortly after I had gotten her up from her afternoon nap, she evidently had another TIA, and for a while only spoke gibberish – complete word salad. Needless to say, this was frightening for her, and she was almost combative in response. After an hour or so she rallied, but it was still a difficult evening until we got her to bed.

We are made of star stuff.
– Carl Sagan, Cosmos.
Ever since Sir Arthur Eddington sorted out the hydrogen fusion theory of star fuel, which led to the understanding of how the elements are created, there has been a growing awareness that we are, quite literally, the stuff of stars. All of the atoms in our bodies were likely forged in the fusion furnaces of stars now long gone.
And those atoms are shared around. Recycled. I remember seeing somewhere a fun calculation that all of us – each and every person alive – carries with them something like 200 atoms which were in the body of Jesus (or, say Nero, Hitler, et cetera…). Whether a person is eaten by a predator, or their body allowed to decompose in the ground, or burned on a pyre, their atoms just go back into circulation and eventually make their way into all of us.
And one day our own sun will change from a hydrogen-fusing star to a helium-fusing star, if only for a little while. It will likely swell up into being a red giant, and when it does it will consume Earth, or atomize it and blast it into space.
So yes, my friend, in a very literal way, my MIL is exactly like a star that’s going into its final flameout. And I find that oddly comforting. And beautiful.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This has been a hell of a day. Not as bad as some, perhaps, but as far as routine days go, not the sort you want to pop up often in the queue. It started with my mother-in-law being ill. Now, most adults know how a young child (either their own or one they’ve babysat) can be when sick. Think intestinal bug. Think explosive diarrhea, of the toxic/caustic variety. Poor kid doesn’t understand what’s going on, or how to best cope with their misbehaving body (if they are capable of that on their own yet). Then picture that not in a toddler, but in a 95-pound woman well into dementia before the effects of dehydration and fever kick in. Took my wife and I two full hours to get her and the bedroom cleaned up.
And then I was on deadline to write my final column for my newspaper. Yeah, my *final* column. My decision, and if I want to go back the paper will be glad to have me. But because of the demands of care-giving, I could not adequately keep up with the art scene in my community (what I wrote about – weird to see that in the past tense). And I was feeling a little burned out with it as well. But still, closing off that particular chapter of my life was somewhat poignant.
So it’s been a day. Which is all just prelude to explaining that one of the refuges I seek after such a day is one of my “regulars”. Typically, it’s Twain, likely his Roughing It, which I have long considered some of his best and funniest work. But tonight, I turn to another old friend I never met: Carl Sagan, particularly his book Pale Blue Dot.
I’ve said before that I’m not a scientist. Which is perhaps why I don’t have some of the same quibbles that many scientists have with Sagan. But I really respect someone who can take scientific research and knowledge and present it in a form an intelligent layperson can understand. Stephen Jay Gould could do that for me. PZ Myers does it for me. So does Carl Zimmer. I could name others, but these are people I respect. In that same way, I really respected Carl Sagan, who I knew more as an author than as the host of of the PBS series, most of which I missed in its initial broadcast. Sagan helped introduce me to whole areas of science I had never considered before, and his considerable human decency in his atheism helped me understand that my own misgivings about religion were not an indication that I was lacking in morals or ethics.
So it was that when I started to write my first novel, Communion of Dreams (unpublished – yeah, yeah, I know I need to finish tweaking the mss and send it out again), I set most of the action on Saturn’s moon Titan, as a tribute to Sagan. Sagan had formulated a theory as to the nature of Titan’s atmosphere (that it contained a complex hydrocarbon he called “tholin”) which accounted for the rusty-orange coloration of the moon. His theories were pretty well borne out by the Huygens probe, by the way, though he didn’t live long enough to know this.
So tonight, on the tenth anniversary of his death, on a day when I’ve been through my own trials, I will nonetheless raise a glass, and drink a wee dram of good scotch to the memory of Carl Sagan. And I’ll promise myself, and his memory, that I’ll get that manuscript tweaked and published, if for no other reason than to honor him.
Here’s to Carl: Sorry you had to leave so soon.

Following back a link to this blog, I came across a great source of space-related links that I thought I’d share: The North Dakota Space Grant Consortium links page.

Via Phil Plait, news that in observation of the 10th anniversary of the Cassini launch, NASA has just released a bunch of very cool images and vids from the probe. Given that I set the bulk of Communion of Dreams there in the neighborhood of Saturn, I always find it stunning to see actual images which reflect what I envisioned. In particular, the scene in the book when the first research team is approaching Titan is perfectly caught in this image. Wow.
And here’s a passage from Plait’s post which precisely echoes my own sentiments, and would be prophetic if Communion was real rather than fiction:
We don’t go to these exotic locations in the solar system because we know everything that’s going on, or because we know what we’ll expect to see. We go because we don’t know. But we also go because we need to have our positions rattled, our notions shaken, our ideas tested. When we see Saturn from above, or co-orbit with a moon, or see a rainbow reflected in particles of ice a billion kilometers away, the only thing we can be sure of is that we’ll see new things, unexpected things.
Unexpected things, indeed.

My good lady wife sent me today’s Astronomy Picture of the Day of ice geysers erupting on Enceladus, one of the inner moons of Saturn. While I don’t mention any of the other moons in Communion, I would imagine that should Titan’s Mistress ever actually be filmed, then such images would be a natural.
Anyway, it’s a cool image, and I thought I’d share.
