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 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 ...

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 ...

A multi-sensor detection of an intense gamma-ray flash, which occurs when two lightning leaders collided, has been observed. Observations across a wide radiation spectrum enabled precise measurement ...

Sarah Dalessi, a fifth-year student in the College of Science at The University of Alabama in Huntsville (UAH), a part of The University of Alabama System, is the lead author of a paper published in ...

GRB 250702B was spotted in July. ESO / A. Levan, A. Martin-Carrillo et al. Astronomers have spotted a gamma-ray explosion unlike any they’ve seen before, with the help of multiple telescopes, ...
