Galactic greetings.


This Christmas tree light-like display is an image of one of our galaxy's centers of new star formation, called W3. It was made by Harvard's and NASA's orbiting Chandra X-Ray Observatory (see here) (named for the great astrophysicist Subrahmanyan Chandrasekhar), and the image was downloaded from Alan Boyle's splendid Cosmic Log, on MSNBC.
