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!

And you can pee upside down, which I did, just for fun. Wouldn’t you?
Great little list about the reality of spaceflight at this point in time. Perfect perspective for this weekend, since he manages to capture and convey the wonder and excitement so many of us felt from the Apollo era. It’s so easy to lose your vision, your enthusiasm, in the grim plodding of day-to-day life.

Thanks to all who helped make the recent anniversary promotion of Her Final Year a success! Worldwide there were about 150 downloads – not a huge number, but it is progress. I hope the book can help those who downloaded it.

Progress continues on St Cybi’s Well. Hope to wrap up Chapter 9 in the next couple of days.

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’.

From Chapter 1 of Communion of Dreams:
“I’ve had my expert do a preliminary search through the old NASA archives. I recalled that they had protocols for dealing with such possible situations, and I doubt that anyone else has really thought much about it since the turn of the century.
“In addition to Don’s field team, the preliminary search suggests that another component should be theoretical, a mix of disciplines so that we can get as broad a spectrum of experience and mind-set as possible. Probably we should have an expert in computer technology. A cultural anthropologist. Someone with a background in game theory and communication strategy. An artist or two. We’ll see if a more thorough survey of the NASA material has any good suggestions beyond that. I’ll get to work identifying appropriate individuals.”
Well, guess what news was announced last week:
During the past few years, NASA has released a series of free ebooks, including NASA Earth As Art and various interactive texts focusing on the Webb and Hubble space telescopes. Last week, they added a new, curious book to the collection, Archaeology, Anthropology, and Interstellar Communication. Edited by Douglas A. Vakoch (the Director of Interstellar Message Composition at the SETI Institute), the text contemplates how we’ll go about “establishing meaningful communication with an extraterrestrial intelligence.” The scholars contributing to the volume “grappl[e] with some of the enormous challenges that will face humanity if an information-rich signal emanating from another world is detected.” And to make sure that we’re “prepared for contact with an extraterrestrial civilization, should that day ever come,” they draw on “issues at the core of contemporary archaeology and anthropology.” Why archaeology and anthropology? Because, says Vackoch, communication with intelligent life probably won’t be through sound, but through images. We will need to read/understand the civilization we encounter based on what we observe.
Heh. I love seeing this stuff happen.
