If you've got the bandwidth, you can download the 706MB version of this image of spiral galaxy M81, showing individual stars, open and globular star clusters, and fluorescent gas clouds from 11.6 million light years away.
The image, compiled from blue, visible and infrared light, is being unveiled at the American Astronomical Society meeting in Honolulu this week. But you can put it on your desktop right now. [SpaceTelescope.org]
