If you don’t know about the Tunguska Event, you might not ever watch the X-Files. I heard about it from my dad when I was a little kid (at the dinner table, where he explained the finer points of fusion vs. fission, the existence of electric cars since the 1960s, and the subatomic process of stars collapsing into black holes).
Well, now there’s a SA-WEEET little video (way short) by Sandia National Laboratory, hosted at the National Geographic website, showing a computer model of the explosion of the comet in the atmosphere (which is the leading theory, right now).
Check it out! The colors are very pretty. Note that it probably looks nothing like the fireworks photo I posted here.
