Story summary

NASA's James Webb Space Telescope has provided new insights into gamma-ray burst (GRB) 250702B, an unusual event lasting hours.
Observations from NASA's Hubble Space Telescope and other telescopes place the explosion in a galaxy about 8 billion light-years away.
Follow-up studies suggest GRB 250702B is a gamma-ray burst, not a tidal disruption event, but evidence remains inconclusive.
The discovery offers a unique opportunity to study stellar and black hole evolution.
