Last night, yet another eye-searing blue meteor screamed across the dark Russian sky. Lucky for us, Russia is the land of dashcams, meaning that yet again

Posted in: Today's ChiliScientists from NASA’s Goddard Space Flight Center recently figured out how to look for extraterrestrial life in tiny samples of space dust using a nanoelectrospray emitter (above, right) that charges molecules into a mass spectrometer (above, left). Previously, they needed large chunks of carbon-rich meteorites to look for signs of aliens.
This is frightening. Nature just published a study by astronomers who have reanalyzed and recalculated the estimate of asteroids that could hit Earth and it’s a lot worse than we thought. Ten times worse.

Posted in: Today's ChiliA few days ago, we admired the cosmic beauty hidden inside of dull-looking meteorites
A few weeks ago, Russian divers extracted a 1,250-pound chunk of the infamous Chelyabinsk meteorite from a lake where it landed on February 15. The massive space stone ended up cracking into three pieces—and though scientists may have cursed the clumsy divers, I was interested in something else: What was inside the rock?
It’s rare for meteoroids falling to Earth to remain intact—only five to ten make it each year—but the ones that do could contain the secrets of the universe or, even better, clues about the origins of life. And it looks like the meteorite that lit up the California sky last year did just that.
Over a hundred years ago, archaeologists dug up these nine blackened, corroded lumps of stone from a pre-dynastic Egyptian cemetery. But it wasn’t until now that we realized just how old they are—and that they came from outer space.
On the outside meteorites look like volcanic rocks. But astronomy photographer Jeff Barton cracks them open to reveal the glittering geodes inside.
As long as you’re not in the immediate landing path, meteorites are really fascinating. Over the past century, The Meteoritical Society has confirmed 606 eyewitnessed meteorite landings around the world. Designer Sebastian Sadowski maps them all out in a great interactive infographic that’s tons of fun, until you realize you’re a meteorite’s sitting duck no matter where you live.
Not all meteor strikes have to be scary, exploding harbingers of an apocalypse to come. More often, in fact, they’re just pretty. This one just screaming on through the Northern Lights even moreso than most. More »
