Every 3 hours, NASA’s Fermi Gamma-ray Space Telescope scans the entire sky and deepens its portrait of the high-energy universe. Every year, the satellite’s scientists reanalyze all of the data it has ...

WASHINGTON — The first gamma-ray burst to be seen in high-resolution from NASA’s Fermi Gamma-ray Space Telescope is one for the record books. The blast had the greatest total energy, the fastest ...

Thanks to improved data analysis techniques and a new operating mode, the Gamma-ray Burst Monitor (GBM) aboard NASA’s Fermi Gamma-ray Space Telescope is now 10 times better at catching the brief ...

Scientists using NASA’s Fermi Gamma-ray Space Telescope have detected beams of antimatter produced above thunderstorms on Earth, a phenomenon never seen before. Scientists think the antimatter ...

In October 2022, astronomers were stunned by what was quickly dubbed the BOAT — the brightest-of-all-time gamma-ray burst (GRB). Now an international science team reports that data from NASA’s Fermi ...

During a powerful solar blast March 6/7, NASA’s Fermi Gamma-ray Space Telescope detected the highest-energy light ever associated with an eruption on the Sun. The discovery heralds Fermi’s new role as ...

July 25 (UPI) --Scientists have announced a never-before-seen energy peak that resulted from the largest gamma ray burst in history, NASA announced Thursday. The brightest-of-all-time gamma ray burst, ...

magine you had superhero vision and could see a whole new world of fascinating phenomena invisible to the human eye. NASA's Fermi Gamma-ray Space Telescope gives astrophysicists analogous powers. It ...

This view shows the entire sky at energies greater than 1 GeV based on five years of data from the LAT instrument on NASA’s Fermi Gamma-ray Space Telescope. Brighter colors indicate brighter gamma-ray ...

NASA’s newest observatory, the Gamma-ray Large Area Space Telescope (GLAST), has begun its mission of exploring the universe in high-energy gamma rays. The spacecraft and its revolutionary instruments ...

The positions of the cataloged pulsars shown in a top-down view of the Milky Way. The red and orange symbols indicate millisecond pulsars, while the green and blue symbols indicate young, unrecycled ...
