| 説明 | Description: The Chandra X-ray image of Hydra A, a galaxy cluster 840 million light years from Earth, shows strands of 35-40 million degree Celsius gas embedded in a large cloud of equally hot gas that is several million light years across. Also a bright white wedge of hot multimillion degree Celsius gas is seen pushing into the heart of the cluster. As the largest gravitationally bound objects in the universe, galaxy clusters provide crucial clues for understanding the origin and fate of the universe.Creator/Photographer: Chandra X-ray ObservatoryNASA'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.Medium: Chandra telescope x-rayDate: 1999Persistent URL: chandra.harvard.edu/photo/1999/0087/Repository: Smithsonian Astrophysical ObservatoryGift line: NASA/CXC/SAOAccession number: hydraA |
