A new method to exploit Gamma-Ray Bursts (GRBs), the most energetic explosions in the universe, as independent measurements of the Universe’s expansion rate has been discovered in optical wavelength.

The longest gamma-ray burst ever recorded did not behave like a quick cosmic flash. Instead, it burned across the sky for ...

Astronomers have caught a cosmic explosion doing something it was never supposed to do, firing off three powerful gamma-ray ...

In a remarkable astronomical event, scientists recently detected the longest gamma-ray burst (GRB) ever recorded, an explosion that lasted an astonishing seven hours. This unprece ...

A seven-hour gamma-ray burst, GRB 250702B, stuns astronomers and hints at powerful new cosmic engines still unknown to science.
