Cambridge, MA – Gamma-ray bursts are the most powerful explosions in the universe, emitting huge amounts of high-energy radiation. For decades their origin was a mystery. Scientists now believe they ...

In 2022, astronomers discovered the brightest gamma-ray burst (GRB) of all time. Now, astronomers confirm that a 'normal' supernova, the telltale sign of a stellar collapse, accompanied the GRB. The ...

Astronomers have detected a gamma-ray burst (GRB) like none other. GRB 250702B was longer than any ever observed and repeated. The GRB was "unlike anything ever witnessed before," according to the ...

It's commonly believed that there's no sound in space, but that's far from the case. For instance, sonifications from NASA have allowed us to hear the sounds of a black hole, and, in 2025, astronomers ...
