Random exciting astronomy stuff

First of all, nifty article from Bad Astronomy on the Moon's youngest known natural crater. This was not present in Apollo 15 images from 1971, but was present in images from the Lunar Reconnaisance Orbiter dating to 2009. So that is very new!

Finally, here is a pretty video of the sun:
