Thanksgiving Dinner At The Center Of The Galaxy
2012-11-22 10:33:45

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.

A team of scientists say they have detected the brightest flare ever observed in our galaxy's black hole.

Chandra Eyes Mini Supermassive Black Hole
2012-10-25 07:19:58

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.

NuSTAR Picks Up First Black Hole X-ray Flare Up

NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) has spotted its first flare from Milky Way's black hole.

Planetary Nebula Survey By Chandra
2012-10-11 05:21:48

An international team of astronomers using NASA's Chandra X-ray Observatory has created a sweeping new survey of dying stars – or planetary nebula – in the neighborhood of the Sun.

Cosmic Superbubble Shows Its Bright Side
2012-08-31 11:01:49

NASA has released a hauntingly beautiful composite image showing a superbubble in the Large Magellanic Cloud (LMC). The LMC is a small satellite galaxy of the Milky Way located about 160,000 light years from Earth.

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...
