Latest Chandra X-ray Observatory Stories
For more than a decade, the astrophysicist at NASA's Goddard Space Flight Center in Greenbelt, Md., experimented with a new technique for efficiently manufacturing super-thin, low-cost curved telescope mirror segments to collect and focus ever-elusive, high-energy X-ray photons.
Astronomers have clocked the fastest wind yet ever discovered blowing off a disk around a stellar-mass black hole.
NASA said on Wednesday that the giant black hole at the center of our Milky Way galaxy may be consuming asteroids.
Vital clues about the devastating ends to the lives of massive stars can be found by studying the aftermath of their explosions. In its more than twelve years of science operations, NASA's Chandra X-ray Observatory has studied many of these supernova remnants sprinkled across the Galaxy.
A Naval Research Laboratory scientist is part of a team that has recently discovered that vast clouds of hot gas are "sloshing" in Abell 2052, a galaxy cluster located about 480 million light years from Earth.
A UC Davis graduate student who is leading a study of the collision of galaxy clusters 5 billion light years away discussed the team’s findings today, Jan. 10, in a press briefing at the annual meeting of the American Astronomical Society in Austin, Texas.
X-Ray Astronomy -- Although the more energetic X-rays (E > 30 keV) can penetrate the air at least for distances of a few meters (they would never have been detected and medical X-ray machines would not work if this was not the case) the Earth's atmosphere is thick enough that virtually none are able to penetrate from outer space all the way to the Earth's surface. X-rays in the 0.5 - 5 keV range, where most celestial sources give off the bulk of their energy, can be stopped by a few...
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. Chandra is designed to observe X-rays from high-energy regions of the universe, such as the remnants of exploded stars. The Observatory has three major parts: (1) the X-ray telescope, whose mirrors focus X-rays from celestial objects; (2) the science instruments which record the X-rays so...
