Singing the holiday blues? Its quite a common affliction. Nothing like a collective brush with death however, to put stuff all back into the proper perspective.

A friend of mine at NASA created this site. Jerry and his friend update it everyday, just for fun. The site has become one of NASA's most popular.

That's no asteroid! It's Santa!

Definitely wouldn't like to have been under the asteroid that made Barringer Crater but my question is, where's the asteroid? Why isn't it sitting there like a cherry on top of a cake?

Zoo, the kinetic energy of the asteroid got converted to heat energy on impact, and almost certainly the heat was sufficient to vaporize the asteroid as well as some of the surface soil it touched. "Vaporized" doesn't mean "gone," of course, and careful analysis of the soil at the impact site would probably provide information about the composition of the asteroid -- stony vs. nickel-iron, for example.

Cheers alumshubby. Of course it would be nicer if it had stayed there but vapoize they must, it would seem.
