Chandra Reveals Outburst From Old Black Holes
2012-04-30 14:03:12

Astronomers using NASA's Chandra X-ray Observatory have found evidence for a population of old stellar black holes. The discovery provides new insight into the nature of stellar black holes, which is a class that can produce as much energy in X-rays as what a million suns could radiate at all wavelengths.

Astronomers Discover New Galaxy Cluster - Musket Ball
2012-04-13 03:33:15

Using a combination of powerful observatories in space and on the ground, astronomers have observed a violent collision between two galaxy clusters in which so-called normal matter has been wrenched apart from dark matter through a violent collision between two galaxy clusters.

A Star Explodes, Turns Inside-Out

A new X-ray study of the remains of an exploded star indicates that the supernova that disrupted the massive star may have turned it inside out in the process.

'Ordinary' Black Hole Discovered 12 Million Light Years Away

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 Clock Record Wind In Stellar-Mass 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...
