Image of the Day: Andromeda in Ultraviolet

A delightful way to expand your image horizons is to subscribe to some of the many institutional "images of the day". NASA has a particularly rich image site, and most of their resources are not under copyright.

Other "images of the day" can be found at Woods Hole Oceanographic Institution, Wikimedia Commons, National Geographic, and The Art Gallery of Greater Victoria.

The following is NASA's description of the image illustrated above:

"In a break from its usual task of searching for distant cosmic explosions, NASA's Swift satellite acquired the highest-resolution view of a neighboring spiral galaxy ever attained in the ultraviolet. The galaxy, known as M31 in the constellation Andromeda, is the largest and closest spiral galaxy to our own. This mosaic of M31 merges 330 individual images taken by Swift's Ultraviolet/Optical Telescope. The image shows a region 200,000 light-years wide and 100,000 light-years high (100 arcminutes by 50 arcminutes)."
