Nova Explosion Reveals Gamma Rays

Facebook X LinkedIn Email
WASHINGTON, Aug. 25, 2010 — Using the Large Area Telescope (LAT) onboard NASA's Fermi Gamma-ray Space Telescope satellite, astronomers have detected gamma rays from a nova for the first time, a finding that surprises both observers and theorists. The discovery dispels the longheld idea that nova explosions are not powerful enough to produce such high-energy radiation. These findings are published in the Aug. 13 edition of Science, with Teddy Cheung, an astrophysicist at the Naval Research Laboratory (NRL), as the lead author. “We know that the remnants of much more powerful supernova explosions can trap and...Read full article
