Amazing astronomical video of a Lunar transit

This video shows a transit of the Moon across the Sun taken by the STEREO-B satellite (it is one of a pair of satellites designed to take 3D images of the Sun). I found this video through Phil Plait’s Bad Astronomy site, and he’s right, it is absolutely breathtaking. Make sure to download the best quality version of the video. At 20MB for 8 seconds it’s a bit hefty, but it’s worth it. Where else can you see motion video of one celestial object crossing in front of another?!
