Latest Chandra X-ray Observatory Stories
New video footage of the Vela pulsar, a neutron star located approximately 1,000 light-years from Earth, suggests that the pulsar could be slowly wobbling as it spins, NASA officials said on Monday.
NASA has released a pair of new images captured by NuSTAR – one depicting a pair of black holes lurking inside a spiral galaxy, and the other featuring a look at the supernova remnant Cassiopeia A.
NASA's NuSTAR spacecraft has detected the Milky Way's central black hole eating a Thanksgiving snack. Supermassive black holes like the one in the middle of our galaxy sustain themselves by swallowing stars, planets, asteroids, comets and clouds of gas that wander around the galaxy.
NASA has released a new image of the Cygnus OB2 star cluster, detailing its structure and evolution.
A team of scientists say they have detected the brightest flare ever observed in our galaxy's black hole.
NASA's Chandra X-ray Observatory has identified one of the lowest mass supermassive black holes ever observed in the middle of a galaxy that one would not expect to harbor this type of beast.
NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) has spotted its first flare from Milky Way's black hole.
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...
