Interesting news item on NPR this morning:
Astronomers have a mystery on their hands. Two large radio telescopes, on opposite sides of the planet, have detected very brief, very powerful bursts of radio waves.
Right now, astronomers have no idea what’s causing these bursts or where they’re coming from. And nothing has been ruled out at the moment — not even the kind of outrageous claims you’d expect to see in tabloid headlines.
* * *
As you would imagine, there’s been lots of speculation about what’s behind these mysterious bursts. Some astronomers think they’re caused by blitzars, pulses of energy from a supermassive star collapsing into a black hole. Others think they may be caused by power solar flares coming from stars nearer by.
And Lorimer says he has to mention it: “There’s even been discussions in the literature about signatures from extraterrestrial civilizations.”
From Chapter 1 of Communion of Dreams when news of the discovery of an evidently alien artifact on Titan is being discussed:
The man sitting next to him got up, stepped up to the holo of the artifact still rotating there in the center. Robert Gish was a little unkempt, his beard untrimmed, his dark hair matted. He was out of shape, almost flabby in appearance. His scientific reputation was as unconventional as his looks. More so. He had been responsible for the radical change in long-range sensing which led to the development of the Advanced Survey Array. Nobel Prize stuff. A true genius, not just brilliant but able and willing to make leaps that took others years to understand. Which was why Bradsen had him here: Gish had been saying for decades that there was other intelligent life among the stars. Saying it so loud and so often that he was considered a crank, since he had no proof and couldn’t even really explain why he believed it to be so, at least in a way that others could accept.
Reaching out as though he was going to touch the object, he said quietly “We know what it is. It is a crack in our shell.”
Interesting news, indeed.

Just think — all the folks who are prepping to deal with some global emergency almost got a chance to see how well their theories work in practice. My friends who are into Steampunk and the SCA would have reigned supreme!
Back in 2012, the Sun erupted with a powerful solar storm that just missed the Earth but was big enough to “knock modern civilization back to the 18th century,” NASA said.
The extreme space weather that tore through Earth’s orbit on July 23, 2012, was the most powerful in 150 years, according to a statement posted on the US space agency website Wednesday.

“If the eruption had occurred only one week earlier, Earth would have been in the line of fire,” said Daniel Baker, professor of atmospheric and space physics at the University of Colorado.
Ah well. Better luck next time!

It’s this kind of guesswork that tends to inflame the Drake equation’s critics, those who complain that the equation isn’t predictive, is too open-ended, and doesn’t provide any answers. But “predictive” isn’t really what Drake ever intended.
“It’s a way to frame the problem,” says MIT astrophysicist Sara Seager, about the equation. “In science, you always need an equation—but this isn’t one you’re going to solve. It just helps you dissect everything.”
Definitely worth reading, as well as thinking about.

If you consider the full implications of what is revealed in Communion of Dreams, this might well be a fairly good explanation …
From the brilliant Randall Munroe, of course. Go to his site to see the ‘hidden text’.

Next Wednesday is the 50th anniversary of the release of the classic film “Dr. Strangelove or: How I Learned to Stop Worrying and Love the Bomb.” It’s long been one of my favorite movies, even as a kid. Yeah, I was a strange kid. Don’t act like you’re surprised.
A decade after the release of “Strangelove,” the Soviet Union began work on the Perimeter system—-a network of sensors and computers that could allow junior military officials to launch missiles without oversight from the Soviet leadership. Perhaps nobody at the Kremlin had seen the film. Completed in 1985, the system was known as the Dead Hand. Once it was activated, Perimeter would order the launch of long-range missiles at the United States if it detected nuclear detonations on Soviet soil and Soviet leaders couldn’t be reached. Like the Doomsday Machine in “Strangelove,” Perimeter was kept secret from the United States; its existence was not revealed until years after the Cold War ended.
“Detecting nuclear detonations” … hmm, where have I heard that phrase recently? Oh, yeah:
On the second day of 2014, a small asteroid blew up high in Earth’s atmosphere. It was relatively harmless—the rock was only a couple of meters across, far too small to hit the ground or do any real damage—and it disintegrated over the Atlantic Ocean anyway.
What’s cool is that now we know for sure this is the case: Infrasound detectors designed to listen for nuclear bomb detonations actually heard the explosion from the impact and were able to pinpoint the location of the event to a few hundred kilometers east off the coast of Venezuela.
NASA put together a nice informative video explaining it:
Gee, it sure is a good thing nothing like that has ever hit the territory of the old USSR … er, oops.
And now that I’ve given you a nice dose of fright, let me make it up to you with a reminder that you can download Communion of Dreams (which has it all … game theory, nuclear exchanges, and more than a little of my old strangeness) for free today and tomorrow!
*The title of one of Herman Kahn‘s books about nuclear war/deterrence, and where I think I was first exposed to the concepts behind game theory. I’ve got Schlosser’s book Command and Control on my to-read list when the Kindle price comes down a bit.

Another item that would likely help get this book moving is a different cover. I understand the imagery now that I’ve read the book, but definitely think it will keep hard-core sci-fi fans from buying a copy (and people do judge books by their covers).
Like I said, every so often a comment to this effect will pop up in a review. And I don’t spend much time thinking about it (and I’m not going to change the cover image at this point), but now and then I wonder just what kind of a cover would appeal to ‘hard-core sci-fi fans’ and still make any kind of sense in relation to the story. Maybe some nice images of Saturn or Titan from the Cassini mission? A depiction of some of the spacecraft (which aren’t described in much detail in the book), or perhaps the Titan Prime space station? Go with a charming post-apocalyptic montage of ruined cities and microphotographs of viruses? To me, none of these would fairly represent the story, and to a certain extent would unnecessarily limit the appeal to only ‘hard-core sci-fi fans’.
But I’m curious what others think. So feel free to post a comment here or over on FB. Over even on Amazon, as a comment on an extant review or in new review of your own. In a week or so I’ll go through all the various comments I can find, and pick someone to get a jar of my latest hot sauce (or something else if they don’t want that).
PS: there’s another new short review up on Amazon you might want to take a look at as well.

Wanna be a black-hole hunter? Sure you do! The Galaxy Zoo folks have just launched a new project you should check out:
Black holes are found at the center of most, if not all, galaxies. The bigger the galaxy, the bigger the black hole and the more sensational the effect it can have on the host galaxy. These supermassive black holes drag in nearby material, growing to billions of times the mass of our sun and occasionally producing spectacular jets of material traveling nearly as fast as the speed of light. These jets often can’t be detected in visible light, but are seen using radio telescopes. Astronomers need your help to find these jets and match them to the galaxy that hosts them.
We live in the glorious future, where beer concentrate is a real, practical thing!
For fans of craft beer, enjoying a decent brew while hiking or camping away from the car usually involves lugging around heavy cans of beer, which can turn a lovely trek into a grueling slog through the woods.
But now the folks at Pat’s Backcountry Beverages have created a solution – their new Brew Concentrates come in featherweight 50ml packets and can be reconstituted with carbonated water (courtesy of their trail-ready 16-ounce carbonator bottle).
Well, actually, the past wasn’t so bad in some ways, either …
When you think of illicit substances that are shipped in brick form, wine probably doesn’t come to mind first. And no, boxed wine doesn’t count. During Prohibition, however, drinkers got around laws that banned alcohol by dissolving bricks of grape concentrate in water and fermenting them into wine.
Of course, conscientious makers of grape bricks didn’t want to contribute to bad behavior, and responsibly warned buyers that, “After dissolving the brick in a gallon of water, do not place the liquid in a jug away in the cupboard for twenty days, because then it would turn into wine.” The makers of the Vino Sano Grape Brick even dutifully indicated what flavors one’s careless handling of grape bricks would result in: burgundy, sherry, port, claret, riesling, etc.
