Intriguingly, the gamma-ray signal detected by NASA’s Fermi Gamma-ray Space Telescope is found in a similar direction and with a nearly identical magnitude...

A new movie from NASA’s Fermi mission shows the intensity of gamma rays — the highest-energy form of light — with energies above 200 million...

Using an array of ground and space-based telescopes, including the NASA/ESA/CSA James Webb Space Telescope, NASA’s Fermi Gamma-ray Space Telescope, and...

New results from the High Altitude Water Cherenkov (HAWC) observatory extend the bright, hard gamma-ray emission from the solar disk observed with NASA’s...

Using data from NASA’s Fermi Gamma-ray Space Telescope and the IceCube Neutrino Observatory, astrophysicists have found preliminary evidence for gamma-ray...

The new animation shows the gamma-ray sky’s frenzied activity during a year of observations by the Large Area Telescope (LAT) aboard NASA’s Fermi Gamma-ray...

Spider binary systems contain a pulsar — the superdense, rapidly rotating remains of a star that exploded as a supernova — that slowly erodes...

Astronomers have examined data about 700 short gamma-ray bursts (GRBs) detected with NASA’s Neil Gehrels Swift Observatory, Fermi Gamma-ray Space Telescope,...

Gamma-ray bursts (GRBs) come in two varieties, long and short. Long GRBs, which last a couple of seconds to one minute, form when a star at least 10 times...

The significant gamma-ray emission is coming from a population of millisecond pulsars within the Sagittarius dwarf spheroidal galaxy, an elliptical loop-shaped...

SNR G106.3+2.7, a supernova remnant located about 2,600 light-years away in the constellation of Cepheus, is producing protons with energies 10 times greater...

Until now, it has been unclear what created gamma-rays that appear in patches of seemingly ‘empty sky.’ Roth et al. present a calculation of the contribution...

Most known supernova-powered gamma-ray bursts are ‘long’ (lasting more than two seconds), but a gamma-ray burst event called GRB 200826A lasted just...

Astronomers using data from NASA’s Fermi Gamma-ray Space Telescope have identified 14 candidate antistars — stars made of antimatter — in...

Using data from NASA’s Fermi Space Telescope and the enormous computing power of the citizen science project Einstein@Home, astronomers have found that...

Around five years ago, NASA’s Fermi Gamma-ray Space Telescope detected high-energy gamma rays coming from TXS 0128+554, an elliptical galaxy located...

A nova is a sudden, short-lived brightening of an otherwise inconspicuous star. It occurs when a stream of hydrogen from a companion star flows onto the...

Using data from the Large Area Telescope (LAT) on board NASA’s Fermi Gamma-ray Space Telescope, astronomers have discovered a gamma-ray glow around Geminga,...

Gamma rays — the most energetic waves in the electromagnetic spectrum — are typically produced by the hottest, most extreme objects in the...

Astronomers using NASA’s Fermi Gamma-ray Space Telescope and NSF’s Karl G. Jansky Very Large Array have spotted a pulsar hurtling through space at...
