Longer analysis of the Russian fireball
I was fascinated by the Russian fireball several days ago, partly because I've been concerned about both the space junk problem and the end-of-civilization scenarios that are posed by a larger impactor. So this analysis was interesting of how big it was, where it came from, and how much energy was released.
