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

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

On 2 July 2025, NASA’s Fermi Gamma-ray Space Telescope observed a gamma-ray burst (GRB 250702B) of a record seven hours in ...

Terrestrial Research (NJIT-CSTR) have uncovered the elusive source of intense gamma rays unleashed during solar flares. These ...

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 ...

Watch a cosmic gamma-ray fireworks show in this animation using just a year of data from the Large Area Telescope (LAT) aboard NASA’s Fermi Gamma-ray Space Telescope. NASA's Marshall Space Flight ...

Solar physicists say they have found a key source of intense gamma rays unleashed when Earth's nearest star produces its most ...

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 ...

A nearby supernova in 2023 offered astrophysicists an excellent opportunity to test ideas about how these types of explosions boost particles, called cosmic rays, to near light-speed. But surprisingly ...

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 ...

An international science team says NASA’s Fermi Gamma-ray Space Telescope has observed high-energy light from solar eruptions located on the far side of the sun, which should block direct light from ...

NASA’s Hubble Space Telescope captured this view of spiral galaxy Messier 101, also known as the Pinwheel galaxy. The location of supernova 2023ixf is circled. On May 18, 2023, a supernova erupted in ...
