The unexpectedly powerful light from the brightest space explosion ever seen may mean that space is more transparent than we thought. Last year, astronomers witnessed a flash of gamma rays that was ...

A strange gamma-ray explosion that fired off repeated bursts from the same patch of sky over roughly seven hours has now been traced to its likely cause: a black hole ripping apart a star that strayed ...

A flash of high-energy light from deep space has forced astronomers to rethink what they thought they knew about the most violent explosions in the universe. The event, a strange gamma-ray burst that ...

Scientists have been all aflutter since several space-based detectors picked up a powerful gamma-ray burst (GRB) in October 2022—a burst so energetic that astronomers nicknamed it the BOAT (Brightest ...

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 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.

Some of the universe's most energetic and mysterious light shows, long gamma-ray bursts, could be generated after dense dead stars collide to create infant black holes surrounded by a natal disk of ...

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 ...

Two neutron stars begin to merge in this artist’s concept, blasting jets of high-speed particles. Collision events like this one create short gamma-ray bursts. Credit: NASA’s Goddard Space Flight ...

Amy Lien receives funding from the NASA Citizen Science Seed Funding Program. When faraway stars explode, they send out flashes of energy called gamma-ray bursts that are bright enough that telescopes ...
