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.

Binary neutron star mergers, cosmic collisions between two very dense stellar remnants made up predominantly of neutrons, ...

Scientists 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.

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.
