US EditionScientists discover a powerful and surprisingly long-lasting gamma ray explosion outside our galaxy
The gamma-ray burst GRB 250702B lasted 100 to 1,000 times longer than typical bursts and repeated over a day, challenging existing models of cosmic explosions, astronomers reported.
- Scientists have discovered a gamma ray explosion outside our galaxy that is exceptionally powerful and long-lasting.
- Telescopes on Earth and in space, including Hubble, have studied the unique explosion of high-energy radiation first observed in July.
- Astronomers reported that the repeated bursts of gamma rays were detected over the course of a day, which is highly unusual.
- The nature of the long-lasting explosion remains a puzzle for scientists to solve.

Astronomers puzzled by repeating gamma ray bursts outside Milky Way
The unknown phenomenon repeated several times over the course of a day, an event unlike anything ever witnessed before.
Never before has such a long and repeated outbreak been detected. Known scenarios provide no explanation for the enormous explosion so far.
A Giant Burst of Energy In Need Of An Explanation
Astronomers have detected an explosion of gamma rays that repeated several times over the course of a day, an event unlike anything ever witnessed before. It took place in a distant galaxy and was first detected on July 2nd. Scientists are trying to understand what could've caused it.
Astronomers have detected over one day a follow-up of gamma rays (GRB), the most powerful explosions in the universe, coming from one source, a phenomenon that has never been observed and which no scenario can explain, according to a report issued by the Australian Observatory (ESO).
Astronomers discover repeating gamma-ray burst 'unlike anything we have ever witnessed before'
A newly discovered gamma-ray burst is unlike any seen before, repeating over the course of a day rather than erupting in milliseconds, leaving astronomers perplexed by its origins.
An unusually long and repetitive gamma burst was observed a few billion light years from our Solar System.
