A giant explosion that lit up the sky didn't just rock the cosmos – it absolutely rattled our understanding of the Universe's most powerful outbursts. The gamma-ray burst (GRB) recorded on 2 July 2025 ...

GRB 230906A, a short gamma-ray burst first detected in 2023, points to a faint galaxy embedded within a long stream of torn ...

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 ...

In October 2022, an international team of researchers, including Northwestern University astrophysicists, observed the brightest gamma-ray burst (GRB) ever recorded, GRB 221009A. Now, a ...

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 ...

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 gamma-ray burst traveled through intergalactic space at the speed of light for eleven billion years, during which time the Sun and the planets were born." — Timothy Ferris, in the film version of ...

The gamma ray burst nicknamed the BOAT, or brightest of all time, was so powerful — and the data it yielded so overwhelming — that it still has scientists’ heads spinning in its afterglow nearly two ...

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 ...

April 12 (UPI) --Scientists at Northwestern University said Friday they had confirmed that the cause of the brightest gamma-ray burst ever observed in October 2022 was the destruction of a star, known ...
