NASA's Fermi captures dynamic gamma-ray sky in new animation

Cosmic fireworks, invisible to our eyes, fill the night sky. We can get a glimpse of this elusive light show thanks to the Large Area Telescope (LAT) aboard NASA's Fermi Gamma-ray Space Telescope, which observes the sky in ...

NASA's retired Compton mission reveals superheavy neutron stars

Astronomers studying archival observations of powerful explosions called short gamma-ray bursts (GRBs) have detected light patterns indicating the brief existence of a superheavy neutron star shortly before it collapsed into ...

Gamma rays from a dwarf galaxy solve an astronomical puzzle

A glowing blob known as "the cocoon," which appears to be inside one of the enormous gamma-ray emanations from the center of our galaxy dubbed the "Fermi bubbles," has puzzled astronomers since it was discovered in 2012.
