Gamma-ray bursts (GRBs) are the brightest explosions in the universe. In just a few seconds, they can outshine all the stars in their host galaxy combined, releasing more energy than our sun will emit ...

"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 ...

A flash of high-energy light from deep space has forced astronomers to rethink what they thought they knew about the most violent explosions in the universe. The event, a strange gamma-ray burst that ...

Gamma-ray bursts are the most violent explosions in the universe. In a fraction of a second, they can release more energy than the sun will emit across its entire 10-billion-year lifetime. Most are ...

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 ...

A space explosion detected this summer burned for days on end, making it the longest and most unusual gamma-ray burst ever seen. Gamma-ray bursts are the universe’s most powerful explosions. They ...

Long-duration gamma-ray bursts are some of the most energetic events in the universe, releasing more energy in just a few ...

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 ...
