Astronomers detected a powerful space signal pulsing toward Earth for seven hours, unlike anything seen in years
A high-energy signal lasting over seven hours, first observed in mid-2025, has drawn intense scrutiny from astrophysicists tracking rare cosmic phenomena. Detected by multiple space-based ...
NASA’s Fermi Gamma-ray Space Telescope "detected none of the high-energy gamma-ray light" from a nearby supernova. NASA ...
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 ...
A pancake stack of radioactivity-sensitive films carried through the sky by a balloon was able to take the world's most accurate picture of a neutron star's gamma ray beam. To achieve this, ...
