Two science videos recently featured on the Bad Astronomy blog:
Why the sky is dark at night (not quite as obvious an answer as most would think! )
Great, awesome, magnificient solar eruption, as captured by SOHO and STEREO satellites. Now available in HD, so click on to youtube proper and view it in 720 or 1080 rez from there!
