I was going through my RSS feeds and saw this image. I am a real pushover when it comes to satellite photography of the distant heavens--it's one of the things that makes me happy I am living at this moment in history. (An iPhone would be nice, too.)This photo shows the star Mira, which lies about 420 light years away from Earth in the constellation Cetus. Mira is a well known star, but until it was photographed by NASA's Galaxy Evolution Explorer space telescope, which observes ultraviolet light, no one had ever noticed that the star has a tail. According the National Geographic news, such star tails were not known to exist before.
