Gamma-ray detectors constitute an essential tool in many scientific and industrial applications, ranging from environmental monitoring and nuclear medicine to safeguards verification. Central to their ...

All eyes are on the source of the record-breaking gamma-ray burst that lit up the sky last week. On Oct. 9, a beam of light more energetic than astronomers had ever seen zipped past our planet, ...

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 ...

When faraway stars explode, they send out flashes of energy called gamma-ray bursts that are bright enough that telescopes back on Earth can detect them. Studying these pulses, which can also come ...

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 ...

A bright flash of gamma rays from the constellation Boötes that lasted nearly one minute came from a kilonova, as we described in a new paper. This finding challenges what astronomers know about some ...

The longest gamma-ray burst ever recorded did not behave like a quick cosmic flash. Instead, it burned across the sky for more than seven hours, forcing astronomers to rethink what powers the universe ...

A constellation of tiny satellites could revolutionize the study of the most energetic explosion in the cosmos and help astronomers untangle the mysteries of colliding stellar remnants that produce ...
