It takes a lot of imaging power to capture the awesome aftermath of a star committing suicide. To get this freaktastic death blossom pic of supernova remnant Cassiopeia A, it took three of NASA's Great Observatories, using three different light wavebands. The red is from the Spitzer Space Telescope's infrared data, the yellow is visible data from the Hubble Space Telescope, and the green and blue are X-ray data from the Chandra X-ray Observatory. Cassiopeia went nova 11,300 years ago, but the nova itself would have been visible from Earth just 300 years ago. Image by AP/HO/NASA
