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 ...

Astronomers may have recorded the violent birth of one of the weirdest objects our Universe is capable of producing. In a bizarre gamma-ray space explosion whose light reached Earth in 2023, a team ...

It’s an astronomical version of the tortoise and the hare, with the longest GRB ever recorded releasing more energy than the ...

Gamma-ray bursts are a relatively new field in space science. The first was discovered in the late 1960s, and in the nearly six decades since, there’s never been a discovery quite like this. It may ...

New research suggests that the largest cosmic structure is even bigger and closer to Earth than we knew. It goes against scientists' models of cosmic evolution.

Astronomers have detected the first “heartbeat” of a newborn star within a cosmic explosion, revealing a rapidly spinning magnetar and reshaping the understanding of gamma-ray bursts.

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 ...

Australia's SpIRIT nanosatellite is the first space telescope funded by the Australian Space Agency to carry a scientific instrument built by another nation's space agency. Australia's SpIRIT ...
