The longest gamma-ray burst ever recorded did not behave like a quick cosmic flash. Instead, it burned across the sky for ...

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 team of astronomers including George Washington University physics Ph.D. student Eliza Neights recorded an extraordinary ...

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 ...

Sarah Dalessi, a fifth-year student in the College of Science at The University of Alabama in Huntsville (UAH), a part of The ...

A new study suggests that explosive events in space have the potential to temporarily switch off the natural shield that protects us from harmful solar radiation. By Katrina Miller On Oct. 9, 2022, ...

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 ...

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 ...

Astronomers detected a gamma-ray burst so bright, it effectively blinded most gamma-ray instruments in space. The pulse of intense radiation traveled for about 1.9 billion years to reach Earth.

"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 ...
