By capturing the most energetic light in the sky, the spacecraft continues to teach us about the mysteries of the universe.

The era of multi-messenger astronomy promises rich rewards—and a steep learning curve.

Sensitive gamma-ray “eye” on NASA’s Fermi space telescope continues to provide unprecedented views of violent phenomena in the cosmos.

An excess of gamma rays at the center of the Milky Way, previously discussed as a sign of dark matter, is likely caused by the superdense remains of ancient stars.

Astrophysicists Eric Charles and Mattia Di Mauro discuss the surprising glow of our neighbor galaxy.
