This is so incredibly cool. NASA posted really high def video of the sun that was recorded earlier this week. It's 30 minutes long, but it's getting a TON of hits on the YouTubes because it is amazing to watch.

NSAS has an observatory satellite that films the sun 24/7, in 10 different wavelengths of light. For the video, they assigned each wavelength a color, so it's red, it's yellow, it's blue...and all with a cool soundtrack!
