Gamma rays streaming from stellar explosions stump astronomers
Novas may be a previously unrecognized source of high-energy flashes

There’s a newfound source of gamma rays: explosions on the surfaces of stars. Figuring out how these novas generate such high-energy light might help astronomers understand the lifecycle of those types of stars and how they might evolve into more powerful explosions such as supernovas.
Over the last six years, the Fermi satellite, which scans the sky for gamma rays, has seen bursts of gamma radiation coming from a menagerie of sources such as pulsars and remnants of exploding stars, says Teddy...
