NASA X-Ray Observatory Reveals Magnetars More Common Than Thought
2013-05-24 14:42:15

Lee Rannals for redOrbit.com — Your Universe Online NASA's Chandra X-ray Observatory has revealed that some of the most extreme objects in the universe may be more common than previously thought. Magnetars are the dense remains of dead stars that erupt sporadically with bursts of high-energy radiation. When a massive star runs out of fuel its core collapses to form a neutron star. Most neutron stars spin rapidly, but a small fraction have a relatively low spin rate while also...

Dark Lightning And Visible Lightning May Be Connected
2013-04-25 11:02:17

Watch the video "Scientists Detect Dark Lightning Linked To Visible Lightning" Brett Smith for redOrbit.com - Your Universe Online Discovered in 1991, dark lightning is an electrical phenomenon that occurs deep within a thunderhead and is responsible for producing a powerful burst of radio waves and gamma rays. Now, new research from an international team of scientists has found that dark lightning and visible lightning may be connected, according to a report in Geophysical...

A research team from Birkbeck, University of London, Royal Holloway University and Uppsala University in Sweden, have helped explain how ozone causes severe respiratory problems and thousands of cases of premature death each year by attacking the fatty lining of our lungs. In a study published in Langmuir, the team used neutrons from the Institut Laue-Langevin in Grenoble and the UK's ISIS Neutron Source to observe how even a relatively low dose of ozone attacks lipid molecules that line...

To increase the neutron detection efficiency of Bulk-Micromegas (MICRO-MEsh GAseous Structure) neutron detectors, researchers from Lanzhou University (China), IRFU-CEA (France), and the University of Tennesse-Knoxville (USA) have proposed three novel converters. When validated using Monte Carlo simulations, the design results in a threefold increase in neutron detection efficiencies. This work is described in detail in SCI CHINA: Tech. Sci. 2013, 43(3). The team have now made a...

Little Room Left For Error In Foundations Of Carbon-Based Life
2013-03-14 12:57:03

North Carolina State University Life as we know it is based upon the elements of carbon and oxygen. Now a team of physicists, including one from North Carolina State University, is looking at the conditions necessary to the formation of those two elements in the universe. They´ve found that when it comes to supporting life, the universe leaves very little margin for error. Both carbon and oxygen are produced when helium burns inside of giant red stars. Carbon-12, an essential...

Dense Matter Of Neutron Stars Revealed Through X-Ray Observations
2013-03-07 12:03:35

April Flowers for redOrbit.com - Your Universe Online The densest matter in the Universe outside of black holes is contained in neutron stars, the ultra-dense cores left behind after massive stars collapse. One of the most reliable determinations yet of the relationship between the radius of a neutron star and its mass has been provided by new results from NASA's Chandra, along with European Space Agency's (ESA) XMM-Newton and NASA's Rossi X-ray Timing Explorer (RXTE), which constrain how...

New Technique Could Reveal High Detail Of Earth's Composition
2013-02-22 10:50:16

April Flowers for redOrbit.com - Your Universe Online In a new study recently published in the journal Science, a research team from Amherst College and The University of Texas at Austin has described a new technique that might one day reveal the composition and characteristics of the deep Earth in never before seen detail. There's just a tiny little hitch in the new technique. It relies on a fifth force of nature that has not yet been detected. Current physics theories hold that there...

New Insights Into The Birth And Evolution Of Stars Provided By Gamma Ray Camera
2013-02-05 11:08:45

Science and Technology Facilities Council A major step forward in our understanding of the structure and behavior of some of the most elusive atomic nuclei in existence, some of which occur only briefly on the surface of exploding stars, is now taking place thanks to the first experiments to come from the new Advanced Gamma Tracking Array (AGATA). AGATA has been developed by the STFC´s Nuclear Physics Group, and a group of UK Universities funded by STFC, with the aim of studying...

Space Radiation Detectors Placed Onboard Space Station

[ Watch the Video: Solar Eruption in Full HD ] redOrbit Staff & Wire Reports - Your Universe Online During his trip to the International Space Station (ISS), Canadian astronaut Chris Hadfield carried with him a new set of instruments designed to help measure the amount of radiation an astronaut absorbs during a typical trip into space. The radiation measured by the devices is called neutron radiation. It is one of the more dangerous types officials from the Canadian Space Agency...

Quantum Spin Liquid Is A New State Of Magnetism
2012-12-21 09:38:33

redOrbit Staff & Wire Reports - Your Universe Online While experts had previously only confirmed the existence of two states of magnetism, experts from the Massachusetts Institute of Technology (MIT) report that they have been able to experimentally demonstrate the existence of a third kind. The MIT researchers have dubbed the new state a quantum spin liquid (QSL), and they describe their findings in this week's edition of the journal Nature. It joins ferromagnetism (the simple form...

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...
