Many consider...

NuSTAR Observes Dormant Black Hole In Nearby Sculptor Galaxy
2013-06-12 08:35:23

April Flowers for redOrbit.com - Your Universe Online NASA´s Chandra X-ray Observatory caught signs of what appeared to be a black hole eating gas at the middle of the nearby Sculptor Galaxy nearly a decade ago. A new observation by NASA´s Nuclear Spectroscopic Telescope Array (NuSTAR) has found the black hole asleep. Details of NuSTAR´s findings were published in the Astrophysical Journal. "Our results imply that the black hole went dormant in the past 10 years," said...

John P. Millis, PhD for redOrbit.com — Your Universe Online As telescopes peer into the distant background of the Universe they are, in effect, looking back in time. The light emitted from these objects has been traveling across the Universe for perhaps billions of years. So by analyzing the background light of the sky researchers can get a picture of the composition of the Universe early in its evolution. New data from NASA´s Chandra X-ray Observatory and NASA´s...

Abell 2142, also called A2142 and located in the constellation Corona Borealis, is an X-ray luminous galaxy cluster. Its creation is due to the merger between two galaxy clusters. It is one of the largest objects in the universe and is six million light years across. It holds hundreds of galaxies and enough gas to make a thousand more. The pressure fronts in the system have been traced in detail and are relatively cool 50 million degree Celsius. The central region is embedded in large...

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...

X-ray Burster -- X-ray bursters are a class of binary stars which are luminous in X-rays. They contain a neutron star and a low-mass companion star. The companion fills its Roche lobe and therefore the neutron star is accreting matter from it. The inflowing gas forms an accretion disk around the neutron star. Sometimes X-ray bursters show a sudden increase in their X-ray luminosity, called X-ray burst. All properties of the X-ray bursts can be explained assuming that they result from...

X-ray Binaries -- X-ray binaries are a class of binary stars that are very luminous in X-rays. The X-rays are produced by matter falling from one component (usually a relatively normal star) to the other component, which is a neutron star or a black hole. The infalling matter releases gravitational potential energy, up to several tens of per cent of its rest mass as X-rays. (Hydrogen fusion releases about 0.7 per cent of rest mass) X-ray binaries are further subdivided into...

Variable Star -- Most stars are of nearly constant luminosity. Our own Sun is a good example which goes through practically no measurable variation in brightness. There are, however, stars which do vary in brightness, called variable stars. They fall into two main groups: Intrinsic variables These are stars which have intrinsic variations in brightness, that is the star itself gets brighter and dimmer. There are many types of intrinsic variables, the main types being: -- Mira...
