Cutting-edge computer simulations combined with theoretical calculations are helping astronomers better understand the origin of some of the universe's most energetic and mysterious light shows -- ...

What is the nature of dark energy, a recently discovered dominant constituent of the universe today? Is expansion-accelerating dark energy an intrinsic property of space-time itself or rather a field ...

The longest gamma-ray burst ever recorded did not roar for seconds or even minutes, but for a staggering seven hours, forcing ...

"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 ...

An explosion — about 100 times brighter than previously recorded — blinded scientists' instruments. Scientists marveled at the power of the gamma-ray jet, which likely marked the birth of a black hole ...

When gamma-ray bursts were first discovered by the military, their declassified origin left astrophysicists puzzled. They couldn’t explain how such luminosity could exist. A newly detected burst now ...

Scientists have pinned down the energy produced by an unusually bright gamma-ray burst detected in 2022, and wow is it a whopper. Reading time 2 minutes The gamma-ray burst, affectionately dubbed ...

A snapshot from a simulation showing how the merger of a black hole and a neutron star can generate powerful jets and winds that produce gamma-ray bursts. A new study presents a framework linking the ...
