IMAGE: Remnant Of An Explosion With A Powerful Kick?
2012-02-02 13:47:04

Vital clues about the devastating ends to the lives of massive stars can be found by studying the aftermath of their explosions. In its more than twelve years of science operations, NASA's Chandra X-ray Observatory has studied many of these supernova remnants sprinkled across the Galaxy.

Abell Galaxy Cluster Harbors Sloshing Clouds Of Gas
2012-01-31 05:00:32

A Naval Research Laboratory scientist is part of a team that has recently discovered that vast clouds of hot gas are "sloshing" in Abell 2052, a galaxy cluster located about 480 million light years from Earth.

When Galaxy Clusters Collide
2012-01-10 15:18:03

A UC Davis graduate student who is leading a study of the collision of galaxy clusters 5 billion light years away discussed the team’s findings today, Jan. 10, in a press briefing at the annual meeting of the American Astronomical Society in Austin, Texas.

Image 2 - Slowpoke Pulsar Found Nestled In Young Supernova Remnant
2011-12-20 15:09:57

Astronomers have discovered a very slowly rotating X-ray pulsar still embedded in the remnant of the supernova that created it.

Galaxy Cluster Gets Sloshed Around Like Wine

Like wine in a glass, vast clouds of hot gas are sloshing back and forth in Abell 2052, a galaxy cluster located about 480 million light years from Earth.

Swift Finds Gamma-Ray Burst With A Dual Personality
2011-12-01 04:28:51

A peculiar cosmic explosion first detected by NASA's Swift observatory on Christmas Day 2010 was caused either by a novel type of supernova located billions of light-years away or an unusual collision much closer to home, within our own galaxy.

Black Hole Birth Announcement
2011-11-17 14:40:32

For the first time, astronomers have produced a complete description of a black hole, a concentration of mass so dense that not even light can escape its powerful gravitational pull.

Image Release: Close Encounters Of The Galactic Kind
2011-10-26 02:54:11

Astronomers have used a large survey to test a prediction that close encounters between galaxies can trigger the rapid growth of supermassive black holes.

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...
