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 -- ...

Prof. An Tao from the Shanghai Astronomical Observatory (SHAO) of the Chinese Academy of Sciences has proposed a novel "precessing magnetic jet engine" model to explain the peculiar gamma-ray burst ...

A Black Hole May Have Eaten a Star and Produced the Longest Gamma-Ray Burst Ever Recorded ...

When space telescopes blazed with high-energy radiation for hours earlier this year, astronomers suspected that they were witnessing something special. The cosmic flash GRB 250702B was no ...

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 ...

Scientists from the RIKEN Cluster for Pioneering Research and collaborators have used simulations to show that the photons emitted by long gamma-ray bursts–one of the most energetic events to take ...

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 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 ...

Add Yahoo as a preferred source to see more of our stories on Google. The cosmic flash, known as GRB 250702B, wasn’t just another gamma-ray burst—it was the longest-lasting one ever recorded, blazing ...
