NASA’s Chandra X-ray Observatory has helped astronomers witness the first event of a black hole destroying a star in a dwarf galaxy.

Astronomers Find Youngest-Ever X-Ray Binary
2013-12-05 06:29:43

Using data obtained from NASA's Chandra X-ray Observatory and the Australia Telescope Compact Array, researchers have identified the remains of a supernova that exploded just 2,500 years ago, making it the youngest astronomical object of its kind ever discovered.

Milky Way's Black Hole Shows Off It's Jet Of High-Energy Particles

Many supermassive black holes emit a jet of high-energy particles as a byproduct of engulfing large quantities of mass and energy, and NASA researchers have just discovered that the supermassive black hole at the center of the Milky Way is no different.

During the last few hundred years, the dim region very close to the supermassive black hole near the center of the Milky Way flared up with at least two luminous outbursts, according to a team of researchers using NASA's Chandra X-ray Observatory.

Densest Galaxy Discovered

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...
