Jan. 9, 2023 Astronomers studying archival observations of powerful explosions called short gamma-ray bursts (GRBs) have detected light patterns indicating the brief existence of a superheavy neutron star shortly ...
June 3, 2021 Scientists have gained the best view yet of the brightest explosions in the universe: A specialised observatory in Namibia has recorded the most energetic radiation and longest gamma-ray afterglow of ...
Sep. 20, 2021 Star-forming galaxies are responsible for creating gamma-rays that until now had not been associated with a known ...
Apr. 28, 2021 Analysis of data from a lightning mapper and a small, hand-held radiation detector has unexpectedly shed light on what a gamma-ray burst from lightning might look like - by observing neutrons ...
Aug. 23, 2021 Astronomers have succeeded in quantifying the proton and electron components of cosmic rays in a supernova remnant. At least 70% of the very-high-energy gamma rays emitted from cosmic rays are due to ...
Oct. 25, 2023 Scientists have observed the creation of rare chemical elements in the second-brightest gamma-ray burst ever seen -- casting new light on how heavy elements are ...
Aug. 11, 2022 NASA's Fermi Gamma-ray Space Telescope confirms one supernova remnant as a launch site for some of our galaxy's highest-energy ...
Dec. 19, 2022 When stars die out, they emit gamma-ray bursts. Although scientist can calculate the explosion energy from dying stars, it is difficult to do when the conversion efficiency is low or unknown. Using ...
Sep. 24, 2021 The Universe is filled with energetic particles, such as X rays, gamma rays, and neutrinos. However, most of the high-energy cosmic particles' origins remain ...
Apr. 28, 2022 Researchers have found an alternative explanation for a mysterious gamma-ray signal coming from the center of the galaxy, which was long claimed as a signature of dark ...
