Solar Cell Degradation Seen Directly For The First Time
2013-12-09 16:02:32

DESY X-ray Examination Shows Structural Changes In "Plastics" Solar Cells With the help of DESY’s X-ray light source PETRA III, researchers of Technische Universität München have, for the first time, watched organic solar cells degrade in real time. This work could open new approaches to increasing the stability of this highly promising type of solar cell. The team headed by Prof. Peter Müller-Buschbaum from the Technische Universität München (Technical University of Munich)...

2013-12-05 06:29:43

[ Watch the Video: Millisecond Pulsar with Magnetic Field Structure ] redOrbit Staff & Wire Reports - Your Universe Online 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. The object is an X-ray binary located between 24,000 and 30,000 light years from Earth in the...

WASHINGTON, Dec. 4, 2013 /PRNewswire-USNewswire/ -- Data from NASA's Chandra X-ray Observatory has revealed faint remnants of a supernova explosion and helped researchers determine Circinus X-1 -- an X-ray binary -- is the youngest of this class of astronomical objects found to date. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) As the name suggests, X-ray binaries are star systems made up of two parts: a compact stellar remnant -- either a neutron star or a black...

Intense 2-color Double X-ray Laser Pulses Generated For First Time
2013-12-04 12:47:43

RIKEN A team working at the SACLA X-ray Free-Electron Laser (XFEL) in Japan has succeeded in generating ultra-bright, two-color X-ray laser pulses, for the first time in the hard X-ray region. These light pulses with different wavelengths, whose time separation can be adjusted with attosecond accuracy, are very powerful tools to investigate the structure of matter and the dynamics of ultrafast physical processes and chemical reactions. SACLA is one of only two facilities in the world to...

Lightweight Black Hole Has Elegant Manners
2013-11-29 05:00:59

April Flowers for redOrbit.com - Your Universe Online Our understanding of how some black holes consume matter might be changed by new observations of a black hole powering an energetic X-ray source in a galaxy some 22 million light years away. The findings, published in a recent issue of Nature, indicate that this particular black hole, thought to be the engine behind the X-ray source’s high-energy light output, is unexpectedly lightweight. Additionally, in spite of the generous amount...

DOE/SLAC National Accelerator Laboratory SLAC's linac coherent light source reaches key milestone in decoding biological structures that were out of reach A study shows for the first time that X-ray lasers can be used to generate a complete 3-D model of a protein without any prior knowledge of its structure. An international team of researchers working at the Department of Energy's (DOE) SLAC National Accelerator Laboratory produced from scratch an accurate model of lysozyme, a...

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...
