Scientists 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 tera-electronvolts, or about ten trillion times the energy ...
In 2019, the world was mesmerized by the first-ever image of a black hole, courtesy of the Event Horizon Telescope (EHT). The striking image depicted the supermassive black hole at the center of the ...
WASHINGTON, Nov 14 (Reuters) - About two billion years ago in a galaxy far beyond our Milky Way, a big star met its demise in a massive explosion called a supernova that unleashed a huge burst of ...
In context: Pulsars are rotating neutron stars formed from the remnants of supergiant stars that have undergone supernova explosions. These celestial objects emit beams of highly energetic ...
On the morning of October 9, 2022, multiple space-based detectors picked up a powerful gamma-ray burst (GRB) passing through our Solar System, sending astronomers around the world scrambling to train ...

A view of the past with the farthest supernova ever observed
Astronomers have discovered a supernova so distant that it dates back to a time when the cosmos was still very young, thus ...
Gamma-ray bursts were traced to the nucleus of an ancient galaxy about 3 billion light-years away from Earth. By Laura Baisas Published Jun 23, 2023 9:00 AM EDT Get the Popular Science daily ...
It came from somewhere 2 billion light-years away. And when it arrived in October of 2022, the gamma-ray burst lit up the entire ionosphere. Now astronomers are working in a whole realm of “new ...
Regular high-energy pulses of gamma-ray radiation emerging from around the Milky Way's central black hole may be coming from a blob of matter whipping around at 30% the speed of light. When you ...
On Sunday, Oct. 9, 2022, a pulse of intense radiation swept through the solar system so exceptional that astronomers quickly dubbed it the BOAT – the brightest of all time. The source was a gamma-ray ...
The researchers think that infrared light particles (photons) from the poles of the pulsar are boosted to gamma-ray energies (blue) by fast electrons. Scientists using the H.E.S.S. observatory in ...
