Depending on the circumstances you find yourself in, a Geiger counter can be a tremendously useful tool. With just a click or a chirp, it can tell you if any invisible threats lurk. But a Geiger ...

Scientists have been all aflutter since several space-based detectors picked up a powerful gamma-ray burst (GRB) in October 2022—a burst so energetic that astronomers nicknamed it the BOAT (Brightest ...

A research team led by the Institute of High Energy Physics of the Chinese Academy of Sciences has made a breakthrough discovery. They identified a gamma-ray spectrum line with an energy of up to 37 ...

This study is led by Prof. Shaolin Xiong (Institute of High Energy Physics, Chinese Academy of Sciences) and Prof. Jirong Mao (Yunnan Observatories, Chinese Academy of Sciences) and Prof. Shuang-Nan ...

Gamma-ray bursts (GRBs) are intense, transient cosmic events, typically originating from massive stellar collapses or mergers of compact objects, which serve as crucial probes for understanding the ...

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 ...

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 ...

A single gamma-ray burst has forced astronomers to redraw their mental map of how the most violent explosions in the universe work. Instead of behaving like a textbook blast, this eruption stayed ...

Astronomers have caught a cosmic explosion doing something it was never supposed to do, firing off three powerful gamma-ray bursts from the same source within hours. The triple outburst is forcing ...
