My God, It’s Full of…Planets?

“‘The fact that we’ve found so many planet candidates in such a tiny fraction of the sky suggests there are countless planets orbiting sun-like stars in our galaxy,’ said William Borucki of NASA’s Ames Research Center in Moffett Field, Calif., the mission’s science principal investigator. ‘We went from zero to 68 Earth-sized planet candidates and zero to 54 candidates in the habitable zone, some of which could have moons with liquid water.’“

After its initial sweep of 1/400th of the sky, NASA’s Kepler telescope finds over 1200 planets — 54 of them potentially inhabitable. (The picture above is a rendering of the six-planet Kepler-11 system, 2000 light-years away.)

Discover‘s Phil Plait puts today’s findings in proper perspective: “Mind you, Kepler is only looking at a sample of stars that is one one-millionth of all the stars in the Milky Way. So it’s not totally silly to take these numbers and multiply them by a million to estimate how many planets there may be in the galaxy…70 million Earth-size planets, and a million in the habitable zone of their stars. A frakking million. In our galaxy alone.”

The Art of the Scratch.

“Srivastava realized that the same logic could be applied to the lottery. The apparent randomness of the scratch ticket was just a facade, a mathematical lie. And this meant that the lottery system might actually be solvable, just like those mining samples. ‘At the time, I had no intention of cracking the tickets,’ he says. He was just curious about the algorithm that produced the numbers.“

In Wired, Jonah Lehrer tells the story of how a Canadian statistician broke the code behind lottery scratch-off tickets. “‘It wasn’t that hard,’ Srivastava says. ‘I do the same kind of math all day long.’” (The trick, in brief: Look for numbers that only appear once on a card, in a winning combination.)

Into the Murky Deep.

“It is a smudge of light only a tiny fraction of the size of our own Milky Way galaxy, and it existed when the universe was only 480 million years old…If confirmed, the discovery takes astronomers deep into an era when stars and galaxies were first lighting up the universe and burning their way out of a primordial fog known as the dark ages.“

From a few days ago: The Hubble — also the subject of an excellent IMAX-3D movie I saw on Saturday — (probably) finds the oldest, farthest galaxy yet discovered. “Spectroscopic observations with the forthcoming James Webb Space Telescope, however, are needed to cement the identification of the smudge as a galaxy…The Webb telescope, which is expected to be launched later this decade once NASA figures out how to pay for it, has been designed to find these primordial galaxies and thus illuminate the dark ages.”

V’Ger Sails On.

“‘Needless to say, none of us expected it was going to be operating for so long,’ said Krimigis, now 72. ‘We were all praying to get to Neptune [in 1989]. But after that? Who thought we could be with this 33 years [after launch]?’“

Though it’s past 11 billion miles, it’s feeling very still (after all, no more solar wind)…
By way of a friend, and as the spacecraft reaches the outer edge of the solar system, the Baltimore Sun checks in on Voyager 1 and its makers. “Voyager was the pinnacle of his career, said Ness, now 77. “There is never going to be a mission in anybody’s lifetime, now living, that is ever going to get these observations in hand. So it’s once in a lifetime.“

After Hobbits, Easterlings.

“Along with modern humans, scientists knew about the Neanderthals and a dwarf human species found on the Indonesian island of Flores nicknamed The Hobbit. To this list, experts must now add the Denisovans.” Researchers discover evidence of a fourth separate species of ancient man in the caves of Siberia. “The implications of the finding have been described by Professor Chris Stringer of the Natural History Museum in London as ‘nothing short of sensational… [W]e didn’t know how ancient people in China related to these other humans.‘”

Those Real Life Achieves.

“By one estimate, Dr. McGonigal notes, creating Wikipedia took eight years and 100 million hours of work, but that’s only half the number of hours spent in a single week by people playing World of Warcraft. ‘Whoever figures out how to effectively engage them first for real work is going to reap enormous benefits,’ Dr. McGonigal predicts.“

But, then it’d be work, would it? At any rate, scientists and game designers try to figure out ways to tap into the world-changing potential of gamers. “‘Gamers are engaged, focused, and happy’…’One of the most profound transformations we can learn from games is how to turn the sense that someone has “failed” into the sense that they ‘haven’t succeeded yet.’“

Life…But Not as We Know It.

“Our findings are a reminder that life as we know it could be much more flexible than we generally assume or can imagine,” Felisa Wolfe-Simon, an astrobiology researcher at the U.S. Geological Survey, said.“

Whoa. NASA announces it has discovered a strange new bacteria in California’s Mono Lake that use arsenic instead of phosphorus, previously considered indispensable to life. “It gets in there and sort of gums up the works of our biochemical machinery,’ ASU’s Ariel Anbar, a co-author of the Science paper, explained.

Big doings? Definitely — The existence of these viable microbes suggests new biochemical possibilities for life on distant (or even not-so-distant) planets. But Discover‘s Ed Yong advises caution: “The discovery is amazing, but it’s easy to go overboard with it…For a start, the bacteria – a strain known as GFAJ-1 – don’t depend on arsenic. They still contain detectable levels of phosphorus in their molecules and they actually grow better on phosphorus if given the chance. It’s just that they might be able to do without this typically essential element – an extreme and impressive ability in itself.“

Update: “As soon as Redfield started to read the paper, she was shocked. ‘I was outraged at how bad the science was,’ she told me.” Hold the champagne: Slate‘s Carl Zimmer surveys the scientific pushback, and it is considerable. “‘[N]one of the arguments are very convincing on their own.’ That was about as positive as the critics could get. ‘This paper should not have been published,’ said Shelley Copley of the University of Colorado.”

My God, It’s Full of Stars.

“We may have to abandon this notion of using the Milky Way as a template for the rest of the universe,” Dr. van Dokkum said. If the findings are correct, an undercount of dwarfs would mean astronomers have underestimated the masses of galaxies, and that would mean that galaxies developed earlier and faster than currently thought.“

Another big happening on the astrobiology front. As first seen at Dangerous Meta, a joint Harvard-Yale study published in Nature finds that our universe may have three times as many stars as we thought. “That suggests a universe of roughly 100 sextillion stars, with an approximate margin of error of about 10 times fewer or 10 times more.“

Glimpses of Qward.

“‘What we’d like to do is see if there’s some difference that we don’t understand yet between matter and antimatter,” Professor Hangst said. ‘That difference may be more fundamental; that may have to do with very high-energy things that happened at the beginning of the universe. That’s why holding on to them is so important – we need time to study them.‘”

Scientists at the Large Hadron Collider in Cern have found a way to hold atoms of antimatter for a fraction of a second. “[T]he ability to study such antimatter atoms will allow previously impossible tests of fundamental tenets of physics….'[W]e need a lot more atoms and a lot longer times before it’s really useful – but one has to crawl before you sprint.’”

Guinness for Brains.

“Drinking alcohol was ‘unintentional, accidental, and haphazard until about 10,000 years ago,’ says Satoshi Kanazawaat at Psychology Today. Smart people are generally early adopters and, in the context of human history, ‘the substance [alcohol] and the method of consumption are both evolutionarily novel.‘

Two new studies find a correlation between intelligence and a thirst for alcohol. Hey, I buy it – Thank you, science, for lending support to my vices! And, as Bogey said, “The problem with the world is that everyone is a few drinks behind.”
