After NASA’s Fermi Gamma-ray Space Telescope and Swift Observatory spotted the BOAT, , an international team of astronomers ...

By integrating gamma-ray burst data from NASA's Neil Gehrels Swift Observatory with advanced AI techniques, scientists are now able to estimate the distances of GRBs more accurately.

Find out about the last time and the next time the Earth will be hit by a Gamma-ray Burst.

The gamma-ray signal is measured to have energies higher than 10 GeV, indicating that the system could accelerate particles to even higher energies.

The cosmos comes alive in an all-sky time-lapse movie made from 14 years of data acquired by NASA's Fermi Gamma-ray Space Telescope. Our sun, occasionally flaring into prominence, serenely traces ...

A fizzled example of a gamma-ray burst, the most powerful kind of explosion known in the universe, suggests these outbursts can be surprisingly brief, researchers say.

The Fermi gamma-ray space telescope has discovered around 300 rapidly spinning neutron stars. Each of the newfound objects sweep two beams of radiation across the universe like a cosmic lighthouse.

The gamma-ray source, which also emits X-rays, as observed by NASA's Swift and ESA's XMM-Newton space telescopes, has been shown to be a binary system consisting of a "millisecond pulsar" that ...

The first measurements from the facility that is flying 400 km above Earth outside Europe’s Columbus laboratory, reveal how so-called ‘terrestrial gamma-flashes’ form in the atmosphere.
