Astronomy Picture of the Day

Explanation: Still need to come up with a good new year's resolution? Consider one appropriate for 2009, the International Year of Astronomy; just look up -- experience, learn, and enjoy the changing sky. This 4-minute, time-lapse video is composed from a series of 7,000 images highlighting much of what you could see. Arcing through the sky in a stately reflection of planet Earth's own rotation are Moon, Sun and stars. But the sequence also features satellites and meteors streaking overhead, clouds moving along the horizon changing in a beautiful iridescence, and beaming crepuscular rays.
