Researchers using NASA’s Fermi Gamma-ray Space Telescope have discovered the first gamma-ray pulsar in a galaxy other than our own. The object sets a new record for the most luminous gamma-ray pulsar ...

For more than a decade, NASA’s Fermi Gamma-ray Space Telescope has quietly mapped the high-energy sky, searching for subtle patterns in the cosmic glow. Now a new analysis of its data points to a ...

Scientists have been all aflutter since several space-based detectors picked up a powerful gamma-ray burst (GRB) in October 2022—a burst so energetic that astronomers nicknamed it the BOAT (Brightest ...

This artist's concept shows the entire sky in gamma rays with magenta circles illustrating the uncertainty in the direction from which more high-energy gamma rays than average seem to be arriving. In ...

Jan. 11 (UPI) --Astronomers studying gamma rays said they have found a mysterious phenomenon just outside of the Milky Way. Researchers published the findings in study Wednesday in The Astrophysical ...
