New simulations performed on a NASA supercomputer are providing scientists with the most comprehensive look yet into the ...

NASA supercomputer simulations reveal X-ray and gamma-ray signals emitted in the final milliseconds before neutron star mergers, providing insights for future observatories and gravitational-wave ...

NASA’s Fermi Gamma-ray Space Telescope "detected none of the high-energy gamma-ray light" from a nearby supernova. NASA ...

For the first time, astronomers using NASA’s Fermi Gamma-ray Space Telescope have traced a budding outflow of gas from a cluster of young stars in our galaxy — insights that help us understand how the ...

Watch an animation of a black hole shooting jets of particles through a "collapsing star at nearly the speed of light" and ...

Nearby galaxies undergoing a furious pace of star formation also emit lots of gamma rays, say astronomers using NASA’s Fermi Gamma-ray Space Telescope. Two so-called “starburst” galaxies, plus a ...

Astronomers are trying to understand what caused a series of gamma ray bursts, or GRBs — the most powerful explosions in the universe. These energetic bursts are typically unleashed by the incendiary ...

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 ...

Using technology similar to that found in smartphone cameras, NASA scientists are developing upgraded sensors to reveal more details about black hole outbursts and exploding stars — all while being ...

CAPE CANAVERAL, Fla. — NASA launched a telescope Wednesday to scout out elusive, super high-energy gamma rays lurking in the universe. Glast — a NASA acronym standing for Gamma-ray Large Area Space ...

By tracing solar flare gamma rays, scientists gain new insight into particle behavior that shapes space weather forecasts.

NASA’s high-flying ER-2 airplane carries instrumentation in this artist’s impression of the ALOFT mission to record gamma rays (colored purple for illustration) from thunderclouds. There’s more to ...
