Astronomers have uncovered a mysterious ultra-high energy gamma ray source in space
Deep in the cosmos, an enigmatic object emits gamma rays at energies more than 100 TeV, an intensity far beyond what we typically observe. Discovered in 2021 by the Large High Altitude Air Shower ...
Spanish astronomers have conducted a near-infrared study of an ultra-high energy gamma-ray source designated LHAASO ...
High altitude: composite image of ASgamma showing the aboveground and underground detectors. (Courtesy: ASgamma) Cosmic gamma rays with energies as high as 450 TeV (10 12 eV) have been observed by the ...
A seven-hour gamma-ray burst, GRB 250702B, stuns astronomers and hints at powerful new cosmic engines still unknown to science.
There is no strict theoretical limit on the highest energy of astrophysical gamma rays, so far as I know, but there are some practical limitations. The first is the energy of the particle that ...
Earlier this year, it was reported that Earth was hit by the brightest gamma-ray bursts seen since the dawn of civilization. Now, a team of astronomers has assigned a value to the energy contained in ...
Stephen has degrees in science (Physics major) and arts (English Literature and the History and Philosophy of Science), as well as a Graduate Diploma in Science Communication. Stephen has degrees in ...
The strongest explosions in the universe produce even more energetic radiation than previously known: Using specialised telescopes, two international teams have registered the highest energy gamma ...
Scientists using the H.E.S.S. observatory in Namibia have detected the highest energy gamma rays ever from a dead star called a pulsar. The energy of these gamma rays clocked in at 20 ...
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 ...
