Tycho Supernova Remnant
A false multi-color image of the Type Ia supernova remnant, Tycho. The image is a composite of an X-ray image taken by the orbiting Chandra X-ray Observatory, an infrared image taken by the orbiting Spitzer Space Telescope, and an optical image taken by the 3.5-meter Calar Alto telescope located in southern Spain . The expanding gas cloud is extremely hot, while slightly different expansion speeds have given the cloud a puffy appearance.
