Fermi brings deeper focus to thunderstorm gamma-rays
Greenbelt MD (SPX) Dec 16, 2014
Each day, thunderstorms around the world produce about a thousand quick bursts of gamma rays, some of the highest-energy light naturally found on Earth. By merging records of events seen by NASA's Fermi Gamma-ray Space Telescope with data from ground-based radar and lightning detectors, scientists have completed the most detailed analysis to date of the types of thunderstorms involved. "Remarkably, we have found that any thunderstorm can produce gamma rays, even those that appear to be so weak a m ... read more

Researchers report possible dark matter signal
Researchers with the European Space Agency say they've detected a strange spike in X-rays coming from two cosmic locations - the Andromeda Galaxy and the Perseus Cluster. The astronomers think the strange emissions could be the signal of dark matter. If confirmed, it would be first direct evidence of dark matter. ... more
