Big Picture: The Sun

The Boston Globe's pictorial feature The Big Picture keeps delivering! This time it's the Sun.

That picture, taken by the STEREO spacecraft, shows the Moon transiting the Sun (and I liked it so much it was part of my Top Ten Astronomy Pictures of 2007), and is part of a jaw-dropping video. The other images of the Sun posted at The Big Picture are just as incredible. Sunspots, flares, coronal mass ejections pummeling comets... do yourself a BIG favor, and go check them out.
