Astronomers Detect Record-Breaking Gamma Ray Bursts From …

WebThere are several current theories about the possible causes of gamma-ray bursts. One explanation proposes that they are the result of colliding neutron stars -- corpses of massive stars (5 to 10 times the mass of our Sun) that have blown up as supernovae. WebThe X-Ray Telescope (XRT) aboard NASA's Swift satellite captured light echoes from a soft-gamma-ray repeater. These stellar remnants, which are thought to be highly magnetized neutron stars called magnetars, occasionally belt out a series of X- and gamma-ray flares.
