Gamma-ray bursts reveal largest structure in the universe is bigger and closer to Earth than we knew: 'The jury is still out on what it all means.' When lightning bolts collide, ...

In October 2022, a blast of light from deep space outshone anything humanity has ever witnessed. The gamma-ray burst, later named “The BOAT,” unleashed more energy in seconds than our sun will emit in ...

While the relative proximity of a burst as powerful as GRB221009A is a boon to science, astronomers are not keen to see a gamma-ray burst much closer to Earth. Especially not in our galaxy.

"Our gamma-ray burst sample is not large enough to place better upper limits on the maximum size of the Hercules-Corona Borealis Great Wall than we already have," Hakkila said.

The first gamma-ray bursts were discovered by accident in the 1960's, by spy satellites looking for gamma-rays from secret nuclear bomb tests. Once scientific satellites began looking for them, ...

Gamma rays are the most energetic form of electromagnetic radiation. In just a few seconds, a gamma-ray burst blasts out the same amount of energy that the Sun will radiate throughout its entire life.

A groundbreaking simulation reveals how neutron star mergers forge black holes, generate gamma-ray bursts, and scatter gold ...

The gamma-ray burst was so powerful that it showed up in the scientific data of spacecraft that aren’t even equipped with gamma-ray detectors, including orbiters at Mars and Voyager 1.

S cientists have developed the longest and most complex simulation to date of a binary neutron star collision that results in ...

Study reveals that high-energy cosmic rays are born in magnetic fields during neutron star mergers, a prelude to black holes.
