In the vast expanse of space, something extraordinary happened. A bright flash of light, known as a gamma-ray burst, traveled across the cosmos. This burst was not just any flash; it was a sign of a star's dramatic end. Astronomers, using the powerful Webb telescope, traced this light back to its so
Astronomers have made a big discovery. They found a cosmic explosion that lasted for seven hours. This is the longest gamma-ray burst ever seen. It was detected by NASA's Fermi Gamma-ray Space Telescope on July 2, 2025. The burst, named GRB 250702B, is different from others. It had repeating explosi
Gamma-ray bursts are intense flashes of energy that light up the universe. They were first spotted in the late 1960s, making them a relatively recent discovery in space science. These bursts are short-lived, lasting from a fraction of a second to a few thousand seconds. The bursts are caused by ext
Scientists have been studying the lengths of gamma-ray bursts (GRBs) detected by the BATSE experiment on NASA's Compton Gamma Ray Observatory. They measured the time it takes for 5% to 95% of the burst's light to arrive, known as T90 duration, and the time for 25% to 75% (called T50), from both brig
Scientists have been wondering if gamma-ray bursts come from far-off parts of the universe. If they do, their light should take longer to reach us, making the bursts look stretched out in time. This is called time dilation. Researchers from the Compton Gamma Ray Observatory used data from their Burs
