Astronomers have discovered the shortest-ever gamma-ray burst (GRB) caused by the implosion of a massive star. Using the international Gemini Observatory, a Program of NSF’s NOIRLab, astronomers ...

Gamma-ray bursts, or GRBs, are pretty much the ultimate explosions: Catastrophic releases of energy that can be many, many billions of times brighter than the Sun. They explode with such power that we ...

Scientists have detected a record-breaking blip of high-energy radiation from a collapsing star. Using NASA's Fermi Gamma-ray Space Telescope, astronomers picked up what is known as a gamma-ray burst, ...

In its first five years in orbit, NASA's Swift satellite has given astronomers more than they could have hoped for. Its discoveries range from a nearby nascent supernova to a blast so far away that it ...

Astronomers studying archival observations of powerful explosions called short gamma-ray bursts (GRBs) have detected light patterns indicating the brief existence of a superheavy neutron star shortly ...

Everything we know about our universe is constantly changing. Spacecraft like the James Webb Space Telescope have already changed everything we thought we knew about the early universe, and now ...

A year ago, astronomers discovered a powerful gamma-ray burst (GRB) lasting nearly two minutes, dubbed GRB 211211A. Now, that unusual event is upending the long-standing assumption that longer GRBs ...

A strange flash of gamma rays from space is upending our ideas on stellar collisions. This gamma ray burst (GRB) seems to have come from two stars smashing together near the centre of an old galaxy, a ...

A long-duration gamma-ray burst observed in late 2021 revealed signatures typically associated with short-duration bursts, forcing puzzled scientists to create a new model for the origin of this ...

For nearly two decades, astrophysicists have believed that long gamma-ray bursts (GRBs) resulted solely from the collapse of massive stars. Now, a team of astrophysicists has uncovered new evidence ...

Astronomers have discovered the shortest-ever gamma-ray burst (GRB) caused by the implosion of a massive star. Using the international Gemini Observatory, a Program of NSF’s NOIRLab, astronomers ...
