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

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 -- ...

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

Gamma-ray bursts (GRBs) are among the most powerful explosions in the universe, second only to the Big Bang. The majority of ...

The cosmic record breaker has now been confirmed by astronomers, who see that the James Webb Space Telescope has detected ...

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 cosmos has a way of rewriting its own rulebook, and a single blast of high-energy light has just forced astronomers back to the first page. Earlier this year, a gamma-ray outburst that raged for ...

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 ...

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.

A simulation showing how the merger of a black hole and a neutron star can generate powerful jets and winds that produce gamma-ray bursts. A new study presents a framework linking the physics of such ...
