NASA's Swift, Fermi Probe Fireworks From a Flaring Gamma-Ray Star

January 10, 2013
Swift's X-Ray Telescope (XRT) captured an apparent expanding halo around the flaring neutron star SGR J1550-5418. The halo formed as X-rays from the brightest flares scattered off of intervening dust clouds. Credit: NASA/Swift/Jules Halpern (Columbia Univ.)
