The Sky in Motion.

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.
