Description: This composite image from Chandra X-ray data (colored blue) and optical light data from the Hubble (red, green and yellow) shows a divided neighborhood where some 200 hot, young, massive stars reside. Bubbles in the cooler gas and dust have been generated by powerful stellar winds, which are then filled with hot, X-ray emitting gas. Scientists find the amount of hot gas detected in the bubbles on the right side corresponds to the amount entirely powered by winds from the 200 hot massive stars. The situation is different on the left side where the amount of X-ray gas cannot explain the brightness of the X-ray emission. The bubbles on this left side appear to be much older and were likely created and powered by young stars and supernovas in the past.

Creator/Photographer: Chandra X-ray Observatory

NASA's Chandra X-ray Observatory, which was launched and deployed by Space Shuttle Columbia on July 23, 1999, is the most sophisticated X-ray observatory built to date. The mirrors on Chandra are the largest, most precisely shaped and aligned, and smoothest mirrors ever constructed. Chandra is helping scientists better understand the hot, turbulent regions of space and answer fundamental questions about origin, evolution, and destiny of the Universe. The images Chandra makes are twenty-five times sharper than the best previous X-ray telescope. NASA's Marshall Space Flight Center in Huntsville, Ala., manages the Chandra program for NASA's Science Mission Directorate in Washington. The Smithsonian Astrophysical Observatory controls Chandra science and flight operations from the Chandra X-ray Center in Cambridge, Massachusetts.
