A Soft Gamma Ray Repeater Erupts with High-Energy Flares
Astronomers using NASA's Swift satellite and the Fermi Gamma-ray Space Telescope have been observing frequent blasts from an object that is 30,000 light-years from Earth. The high-energy fireworks are X-ray and gamma-ray flares coming from a rapidly-spinning and super-magnetic remnant of an exploded star -- an unusual type of stellar cinder called a Soft Gamma Ray (SGR) Repeater.
