XMM-Newton And Integral Clues On Magnetic Powerhouses (SpaceDaily)
by Staff Writers Paris, France (ESA) Nov 18, 2008 X-ray and gamma-ray data from ESA's XMM-Newton and Integral orbiting observatories has been used to test, for the first time, the physical processes that make magnetars, an atypical class of neutron stars, shine in X-rays.

New Nano Satellite Mission To Examine Link Between Lightning And Terrestrial Gamma Ray Flashes (Science Daily)
Massive energy releases occur every day in the upper reaches of Earth's atmosphere. Lightning may give rise to these bursts of radiation. However, unlike the well-known flashes of light and peals of thunder familiar to Earth-dwellers, these energy releases are channeled upward and can be detected only from space. Our atmosphere protects us from the effects of this radiation, but the mechanisms ...

Scientists discover how magnetic stars produce X-rays (New Kerala)
Paris, Nov 15 : ESA's (European Space Agency's) XMM-Newton telescope has been used to test, for the first time, the physical processes that make magnetars, an atypical class of neutron stars, produce X-rays.

New Insights on Magnetars (Universe Today)
Neutron stars are leftovers of massive stars (10-50 times as massive as our Sun) that have collapsed under their own weight. Most are only about 20 km in diameter, but they are so compact that a teaspoon of neutron star stuff would weigh about one hundred million tons. Two other physical properties characterize a neutron [...]

Gamma-Ray Evidence Suggests Ancient Mars Had Oceans (SpaceDaily)
An international team of scientists who analyzed data from the Gamma Ray Spectrometer onboard NASA's Mars Odyssey reports new evidence for the controversial idea that oceans once covered about a third of ancient Mars. "We compared Gamma Ray Spectrometer data on potassium, thorium and iron above and below a shoreline believed to mark an ancient ocean that covered a third of Mars' surface ...

Firefly satellite will study thunderstorms (ZDNet)
The Firefly mission is the second project under the new U.S. National Science Foundation (NSF) CubeSat program. The goal of this program is to provide a low cost access to space research. Firefly will be launched in 2010 or 2011 and will try to 'solve the mystery of the most powerful natural particle accelerator in Earth's atmosphere: TGFs, or terrestrial gamma-ray flashes,' according to a NSF ...

Terrestrial gamma rays in Earth's upper atmosphere linked to lightning (New Kerala)
Washington, Nov 18 : Scientists have theorized that massive energy releases known as 'terrestrial gamma rays', which occur every day in the upper reaches of Earth's atmosphere, are linked to lightning and result when high-energy electrons are accelerated upward over thunderstorms.
