Split Personality Star Discovered
2012-07-16 14:42:45

[ Watch the Video ] Lee Rannals for redOrbit.com - Your Universe Online One recently discovered star seems to have a split personality, with both a magnetar and pulsar consuming the object. The European Space Agency (ESA) said the newly discovered star appears to be a pulsar while hiding an intense internal magnetic field like a magnetar. The internal field is many times stronger than its external magnetic field, leading to its entry into the new class of "low-field...

Astronomers Spot Fastest Moving Pulsar Ever
2012-06-29 13:31:30

[ Watch the Video ] Lee Rannals for redOrbit.com - Your Universe Online Researchers may have discovered the fastest moving pulsar ever seen using NASA's Chandra X-ray Observatory and ESA's XMM-Newton. Astronomers used X-ray observations, combined with infrared data from the 2MASS project and optical data from the Digitized Sky Survey to find evidence for the record-breaking pulsar. The XMM-Newton image was produced when a massive star exploded as a supernova, leaving behind a...

NuSTAR To Help Scientists Solve Supernova Explosion Mystery
2012-06-18 04:01:37

[ Watch the Video ] Somewhere in the Milky Way, a massive old star is about to die a spectacular death. As its nuclear fuel runs out, the star begins to collapse under its own tremendous weight. Crushing pressure triggers new nuclear reactions, setting the stage for a terrifying blast. And then... nothing happens. At least that's what supercomputers have been telling astrophysicists for decades. Many of the best computer models of supernovas fail to produce an explosion. At the end of...

Growth Found to be Out of Synch For Black Hole
2012-06-12 11:42:59

New evidence from NASA's Chandra X-ray Observatory challenges prevailing ideas about how supermassive black holes grow in the centers of galaxies. Astronomers long have thought that a supermassive black hole and the bulge of stars at the center of its host galaxy grow at the same rate -- the bigger the bulge, the bigger the black hole. A new study of Chandra data has revealed two nearby galaxies whose supermassive black holes are growing faster than the galaxies themselves. The mass of a...

Black Hole Caught Exiting Host Galaxy
2012-06-05 04:22:57

Lee Rannals for redOrbit.com New observations from NASA's Chandra X-ray Observatory suggest that a black hole is being ejected from its host galaxy at several million miles per hour. The finding could mean that there are many giant black holes that are roaming around undetected out in the vast spaces between galaxies. "It's hard to believe that a supermassive black hole weighing millions of times the mass of the sun could be moved at all, let alone kicked out of a galaxy at enormous...

Chandra Captures Supernova Shock Wave
2012-05-16 03:13:51

Observations with NASA's Chandra X-ray Observatory have provided the first X-ray evidence of a supernova shock wave breaking through a cocoon of gas surrounding the star that exploded. This discovery may help astronomers understand why some supernovas are much more powerful than others. On Nov. 3, 2010, a supernova was discovered in the galaxy UGC 5189A, located about 160 million light years away. Using data from the All Sky Automated Survey telescope in Hawaii taken earlier, astronomers...

Astronomers Catch Supermassive Black Hole Devouring Distant Star
2012-05-02 14:24:52

Lawrence LeBlond for RedOrbit.com [ Watch the Video ] Astronomers have for the very first time captured a supermassive black hole devouring a wandering star that strayed too close to a phenomena that nothing can escape, not even light. Although the star most likely met its demise in an untimely fashion, it is an extraordinary event for science and astronomy, as scientists believe it may provide them with greater clues on the inner workings of dark behemoths nestled away in the hearts...

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...
