Prof. An Tao from the Shanghai Astronomical Observatory (SHAO) of the Chinese Academy of Sciences has proposed a novel ...

A supernova from the early universe looks unexpectedly familiar, challenging ideas about how the first massive stars lived ...

Cutting-edge computer simulations combined with theoretical calculations are helping astronomers better understand the origin of some of the universe's most energetic and mysterious light shows -- ...

An international team of astronomers, working with researchers from University College Dublin and other institutions, has ...

When space telescopes blazed with high-energy radiation for hours earlier this year, astronomers suspected that they were witnessing something special. The cosmic flash GRB 250702B was no ...

The most extreme fireworks in the universe are supposed to follow rules. Gamma-ray bursts, the brightest explosions known, ...

Sarah Dalessi, a fifth-year student in the College of Science at The University of Alabama in Huntsville (UAH), a part of The University of Alabama System, is the lead author of a paper published in ...

A supercomputer simulation of a mere 10 milliseconds in the collapse of a massive star into a neutron star proves that these catastrophic events, often called hypernovae, can generate the enormous ...

Astronomers have determined what caused the brightest cosmic explosion ever recorded. Lasting a matter of minutes, the gamma-ray burst, named GRB 221009A, was observed by astronomers in October 2022.

A 2022 gamma ray burst, the brightest ever detected, may provide a clue on the existence of axion-like particles, one of the possible explanations for dark matter, according to researchers from the ...

Scientists have detected the most distant supernova ever seen, exploding when the universe was less than a billion years old.

Astronomers are trying to understand what caused a series of gamma ray bursts, or GRBs — the most powerful explosions in the universe. These energetic bursts are typically unleashed by the incendiary ...
