A cosmic explosion with an energy equivalent to the output of a billion suns went unnoticed by astronomers until they caught ...

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 ...

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

Gamma-ray bursts, powerful glares of high-energy that wash through the Universe once every day or so are, for a brief time, the brightest objects in the gamma-ray sky. ESA’s Integral gamma-ray ...

The universe's largest structure, the Hercules-Corona Borealis Great Wall, was already a challenge to explain with models of the universe due to its incredibly vast size — and now, using the most ...

Down here at the bottom of our ocean of air, it’s easy to get complacent about the hazards our universe presents. We feel safe from the dangers of the vacuum of space, where radiation sizzles and ...

This artist's impression shows a kilonova produced by two colliding neutron stars. While studying the aftermath of a long gamma-ray burst (GRB), two independent teams of astronomers using a host of ...

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 ...

In 2023, astronomers using NASA’s Chandra X-ray Observatory and Hubble Space Telescope spotted an unusual class of short ...

Add Yahoo as a preferred source to see more of our stories on Google. The orange dot at the center of this image represents a powerful explosion that repeated several times over one day. - A. Levan, A ...
