Cartão Postal De Festividades XRay Santa Claus in Orion

NASAs XRay Santa Claus in Orion Right in time for the festive season, this image of the Orion nebula combines NASA's Spitzer Space Telescope infrared light with X-ray light to reveal a huge cloud of high-temperature gas resting in a spectacular nearby star-forming region, shaped somewhat like the silhouette of Santa Claus. An early present for astronomers, the cloud suggests that hot gas from many star-forming regions leaks into the interstellar medium. The Orion nebula is the nearest dense star-forming region to Earth that contains stars much more massive than the Sun.
