NASA’s James Webb Space Telescope reveals new clues about a mysterious cosmic explosion that defies expectations.

Astronomers spend careers watching stars collapse and explode, but an eruption spotted in July pushed beyond anything seen before. The event, called GRB 250702B, released high-energy radiation for ...

NASA astronomers recently spotted a burst of radiation that was quickly crowned the "BOAT": the brightest of all time. The source of the radiation, which NASA said "swept through the solar system" on ...

March 29 (UPI) --A gamma-ray burst, which lit up our galaxy last October, was the "brightest burst" ever seen and a once-in-10,000-year explosion, according to NASA. Astronomers have been studying the ...

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

When a distant galaxy briefly outshines everything around it in high-energy light, astronomers usually know which playbook to reach for. Gamma-ray bursts tend to fall into familiar categories, either ...

On Sunday, Oct. 9, 2022, a pulse of intense radiation swept through the solar system so exceptional that astronomers quickly dubbed it the BOAT – the brightest of all time. The source was a gamma-ray ...

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 ...

An international team from China and Italy has reported a possible cosmic encore to the landmark 2017 multi-messenger ...
