For those of us who are space obsessed like me, NASA has released images and movies of this week's comet fly by of the Sun. The in question is the comet ISON, and it is currently making a very close approach to the Sun. It is uncertain if the comet will survive this encounter. The hope is that, if the comet survives and comes around the Sun intact, the comet's tail can be analyzed and help scientists learn more about the beginnings of the solar system. You can read more about it here and here.
