[ Watch the Video ] redOrbit Staff & Wire Reports - Your Universe Online ESA's XMM-Newton has helped to reveal the violent behavior of a young Sun-like star spinning at high speed and spewing out super-hot plasma. Along with information from NASA’s Chandra and Japan’s Suzaku, the findings shed new light on one of the most primary issues in astronomy: the birth of stars like our own Sun. Such stars are born from clouds of gas and dust. These fall apart under gravity and...
Using the compound eyes of the humble moth as their inspiration, an international team of physicists has developed new nanoscale materials that could someday reduce the radiation dosages received by patients getting X-rayed, while improving the resolution of the resulting images. The work, led by Yasha Yi-a professor of the City University of New York, who is also affiliated with Massachusetts Institute of Technology and New York University-was published today in the Optical Society's...
NEWPORT NEWS, Va., July 3, 2012 /PRNewswire/ -- Burlington Medical Supplies, a radiation protection and x-ray medical supply company, now offers no fog lenses. These lead glasses are the latest in technology for healthcare professionals who work in scatter radiation environments, such as doctors, nurses and technologists. These glasses are made with hi-lite transmission leaded glass that is treated with a unique thermally cured coating. They can be cleaned with any standard lens...
The X-ray digitization and markup system known as the PostureRay is a very advanced and useful tool in patient education, x-ray analysis and markup. Dr. Shoshany has recently acquired the system to add to his ever expanding chiropractic, physical therapy and pain management practice. New York, NY (PRWEB) June 30, 2012 Having recently expanded his Active Release Techniques offerings in Manhattan, Dr. Steven Shoshany was also keeping his Manhattan chiropractic practice at the forefront of...
[ 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...
Lee Rannals for redOrbit.com - Your Universe Online NASA said on Thursday that its Nuclear Spectroscopic Telescope Array (NuSTAR) has taken its first test images of a high-energy X-ray universe. The observatory is the first space telescope with the ability to focus high-energy X-rays, which are the same kind used by doctors and dentists, into images. The mission will begin with exploring hidden black holes, specifically looking for fiery cinder balls left over from star explosions....
Lee Rannals for redOrbit.com - Your Universe Online Astronomers have observed one planet in another solar system, similar to Jupiter, giving off a powerful burst of evaporation after passing by its parent star. Using the Hubble Space Telescope, astronomers saw exoplanet HD 189733b bathe in an intense X-ray radiation after its parent star gave off a violet flare. The team observed the planet with Hubble during early 2010 and late 2011, during which HD 189733b was silhouetting its...
For the first time, Lawrence Livermore researchers and international collaborators have peered into the makeup of complex airborne particulate matter so small that it can be transported into human lungs -- usually without a trace. The structure of micron-size particulate matter is important in a wide range of fields from toxicology to climate science (tobacco smoke and oil smoke particles are typically one micron in size). However, its properties are surprisingly difficult to measure in...
"For the first time we can actually see the structure of individual aerosol particles floating in air, their 'native habitat'," said DESY scientist Henry Chapman from the Center for Free-Electron Laser Science (CFEL) in Hamburg. "This will have important implications for various fields from climate modelling to human health." CFEL is a joint venture of Deutsches Elektronen-Synchrotron DESY, the German Max Planck Society and the University of Hamburg. Aerosol particles like soot play...
VANCOUVER, June 27, 2012 /PRNewswire/ - Rockwell Diamonds Inc. ("Rockwell" or the "Company") (TSX: RDI) (JSE: RDI) (OTCBB: RDIAF) announces the results of its diamonds sales for the first quarter of fiscal 2013. Total proceeds of US$5.9 million were generated from the sale of 6,234 carats at an average price per carat for the quarter of US$944. This includes the sale of 1,005 carats from the proof of concept bulk x-ray machine that were sold for an average price per carat of...

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: --...
