NASA | Stellar Odd Couple Makes Striking Flares
Every 3.4 years, pulsar B1259--63 dives twice through the gas disk surrounding the massive blue star it orbits. With each pass, it produces gamma rays. During the most recent event, NASA's Fermi observed that the pulsar's gamma-ray flare...

Fermi Detects Gamma-ray Puzzle from M31
NASA's Fermi Gamma-ray Space Telescope has found a signal at the center of the neighboring Andromeda galaxy that could indicate the presence of the mysterious stuff known as dark matter. The gamma-ray signal is similar to one seen by...

NASA | Gamma-Ray "Raindrops" From Flaring Blazar
This visualization shows gamma rays detected during 3C 279's big flare by the LAT instrument on NASA's Fermi satellite. The flare is an abrupt shower of "rain" that trails off toward the end of the movie. Gamma rays are represented as...
