I'd have to read more; I want to know why they think this impact occurred 250 million years ago. Still, it's cool that they found a really big impact structure in Antarctica.

Not a dupe post but FR had it before Space.com

Bush's fault. I don't know how, but he's behind it.

Two days after the impact, Nancy Pelosi toured the devastated area and derided the administration for lack of leadership.

Cool post

Just the landing crater for the Shoggoths.

Tekeli-li!

[Empireoftheatom48]

Now that's a big bang! If only there was one 1/8 that size heading for Iran! Probably still too big to just limit damage to that wonderful Islamic paradise!!

I gots to get my eyes checked. I thought it said "Judge Crater found....

Jeez - imagine the energy released from a 30 miles wide rock hitting the Earth. Amazing that anything survived.

ALGORE landed here about that same time didn't he? Need i say more?

[LibWhacker]

Very cool they found it. Jeez... 250 million years ago... You've got to wonder what earlier mass wipeouts occurred. There must've been many.

The crater, buried beneath a half-mile of ice and discovered by some serious airborne and satellite sleuthing, is more than twice as big as the one involved in the demise of the dinosaurs.

I didn't know that the "dinosaurs were killed by a meteor" theory had graduated to fact.

[NormsRevenge]

The newfound crater is more than twice the size of the Chicxulub crater in the Yucatan peninsula, which marks the impact that may have ultimately killed the dinosaurs 65 million years ago. The Chicxulub space rock is thought to have been 6 miles wide, while the Wilkes Land meteor could have been up to 30 miles wide, the researchers said.

A 30 mile wide chunk can leave a mark.

That it is under a thick layer of ice and they can still detect it is pretty cool.

Why 250 million years ago. and what else lies out there.. not sure. we need more spaceborne instruments, more eyes on the sky, it's a busy place out there, stuff flying all over..

Interesting

Now, that's how I want to die. Splat. Done.

Asteroid or comet triggered death of most species 250 million years ago

Earth's most severe mass extinction - an event 250 million years ago that wiped out 90 percent of all marine species and 70 percent of land vertebrates - was triggered by a collision with a comet or asteroid, according to new findings by a team led by a University of Washington scientist.

The collision wasn't directly responsible for the extinction but rather triggered a series of events, such as massive volcanism and changes in ocean oxygen, sea level and climate. Those in turn led to species extinction on a wholesale level, said Luann Becker, UW acting assistant professor of Earth and Space Sciences.

"If the species cannot adjust, they perish. It's a survival-of-the-fittest sort of thing," Becker said. "To knock out 90 percent of organisms, you've got to attack them on more than one front."

It looks like they actually found Magneto's Antarctic lair, ha ha ha

And Bush did nothing to prevent it.
