By now, everyone has probably already heard about the meteorite that exploded over the Chelyabinsk city in Russia. There are tonnes of videos on YouTube and photos all over the web. I think this one, that meshes a few of them together, is pretty good.
And as far as comments go, I think this Slashdot comment is the best:
Meteors are the universe’s way to ask hows your space program going.
And the last thing I want to add on the subject is that I’m really glad nobody is dead. A lot of people were injured, and there is plenty of damage to buildings, but that all is repairable. If that trajectory of that thing was slightly different, and it hit the ground before exploding, I imagine the damage would be way greater.
