Astronomers are puzzled by a powerful explosion in space that lasted hours, unlike any other similar event. The James Webb Space Telescope helped scientists study this unusual burst.
A team of researchers is investigating a strange cosmic event that has left astronomers searching for answers. At the center of the mystery is an unusually powerful explosion in space that lasted far longer than anything previously observed. NASA announced that researchers using the James Webb Space Telescope examined GRB 250702B, a long gamma-ray burst and one of the most energetic types of events in the universe.
Gamma-ray bursts typically occur when a massive star collapses into a black hole, producing a brief and intense flash of high-energy gamma rays. This event behaved very differently.
