Are gamma-ray bursts powered by a star’s collapsing magnetic fields? When a massive star in a distant galaxy collapses, forming a black hole, two giant jets of light-emitting plasma shoot from its core. These extremely […]
Fermi mission links nearby pulsar’s gamma-ray ‘halo’ to antimatter puzzle NASA’s Fermi Gamma-ray Space Telescope has discovered a faint but sprawling glow of high-energy light around a nearby pulsar. If visible to the human eye, […]
A Physicist Has a Bold Plan to Make a Gamma-Ray Laser With The Help of Antimatter We can use just about any part of the electromagnetic spectrum to make a laser – from long-wave microwaves […]
Hubble studies gamma-ray burst with the highest energy ever seen New observations from the NASA/ESA Hubble Space Telescope have investigated the nature of the gamma-ray burst GRB 190114C. Gamma-ray bursts are the most powerful explosions […]
Astronomers investigate a curious case of a supernova connected with gamma-ray burst Using a set of space and ground-based telescopes, an international team of astronomers has conducted a detailed study of the supernova SN 2017htp […]
Astronomers observe blazar S5 0836+710 during high activity period, detect two gamma-ray flares Italian astronomers have conducted multi-band observations of the high-redshift blazar S5 0836+710 during its period of high activity. The monitoring campaign resulted […]
