Latest Chandra X-ray Observatory Stories
Observations of how the youngest-known neutron star has cooled over the past decade are giving astronomers new insights into the interior of these super-dense dead stars.
A new image from NASA's Chandra and Spitzer space telescopes shows the dusty remains of a collapsed star. The dust is flying past and engulfing a nearby family of stars.
Astronomers have come across what appear to be two of the earliest and most primitive supermassive black holes known.
New images from NASA's Fermi Gamma-ray Space Telescope show where supernova remnants emit radiation a billion times more energetic than visible light.
NASA will hold a teleconference with reporters at 1 pm EST on Wednesday, Feb 17, to discuss the latest Chandra X-ray Observatory findings that advance our understanding of certain supernovae.
Astronomers have found the first clear evidence of a binary quasar within a pair of actively merging galaxies.
Two spectacular tails of X-ray emission have been seen trailing behind a galaxy using the Chandra X-ray Observatory.
Many of the best computer models of supernova explosions fail to produce an explosion - Instead, according to the simulations, gravity wins the day and the star simply collapses.
NASA has extended a contract with the Smithsonian Astrophysical Observatory in Cambridge, Mass, to provide science and operational support for the Chandra X-ray Observatory, a powerful tool used to better understand the structure and evolution of the universe.
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...
