For the first time, researchers have confirmed the existence of antimatter in the Earth's magnetosphere, BBC News reported on Sunday. Writing in Astrophysical Journal Letters, the researchers report that they discovered a thin band of antiprotons lying in between the inner and outer Van Allen radiation belts using the PAMELA (Payload for Antimatter Matter Exploration and Light-nuclei Astrophysics) satellite. Though the British news organization claims that only a small number of antiprotons...

ESA's XMM-Newton space observatory has watched a faint star flare up at X-ray wavelengths to almost 10 000 times its normal brightness. Astronomers believe the outburst was caused by the star trying to eat a giant clump of matter. The flare took place on a neutron star, the collapsed heart of a once much larger star. Now about 10 km in diameter, the neutron star is so dense that it generates a strong gravitational field. The clump of matter was much larger than the neutron star and came...

Mainz has the most powerful source of ultracold neutrons, opening up the possibility of conducting a key experiment to determine the life time of the neutron Scientists at Johannes Gutenberg University Mainz (JGU) have built what is currently the strongest source of ultracold neutrons. Ultracold neutrons (UCNs) were first generated here five years ago. They are much slower than thermal neutrons and are characterized by the fact that they can be stored in special containers. This property...

Neutron analysis of the atomic dynamics behind thermal conductivity is helping scientists at the Department of Energy's Oak Ridge National Laboratory gain a deeper understanding of how thermoelectric materials work. The analysis could spur the development of a broader range of products with the capability to transform heat to electricity. Researchers performed experiments at both of ORNL's neutron facilities -- the Spallation Neutron Source and the High Flux Isotope Reactor -- to learn why...

MESSENGER carries a Gamma-Ray Spectrometer (GRS) that is capable of measuring and characterizing gamma-ray emissions from the surface of Mercury. Just like radio waves, visible light, and X-rays, gamma rays are a form of electromagnetic radiation, but with higher energies than those other types of radiation. Gamma rays coming from Mercury carry information about the concentrations of elements present on its surface, so observations from the MESSENGER GRS are being used to determine the...

When one cloud of gas meets another, they normally pass right through each other. But now, MIT physicists have created clouds of ultracold gases that bounce off each other like bowling balls, even though they are a million times thinner than air "” the first time that such impenetrable gases have been observed. While this experiment involved clouds of lithium atoms, cooled to near absolute zero, the findings could also help explain the behavior of similar systems such as neutron stars,...

WASHINGTON, April 7, 2011 /PRNewswire-USNewswire/ -- A new supercomputer simulation shows the collision of two neutron stars can naturally produce the magnetic structures thought to power the high-speed particle jets associated with short gamma-ray bursts (GRBs). The study provides the most detailed glimpse of the forces driving some of the universe's most energetic explosions.

The study provides the most detailed glimpse of the forces driving some of the universe's most energetic explosions. The state-of-the-art simulation ran for nearly seven weeks on the Damiana computer cluster at the Albert Einstein Institute (AEI) in Potsdam, Germany. It traces events...

NASA said on Wednesday that its Chandra X-ray Observatory discovered the first direct evidence for a superfluid, a bizarre, friction-free state of matter at the core of a neutron star. According to the space agency, superfluids created in laboratories on Earth exhibit remarkable properties, such as the ability to climb upward and escape airtight containers. NASA said the finding has important implications for understanding nuclear interactions in matter at the highest known densities....

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...
