Record-Breaking Gamma Ray Burst Traced to Black Hole Engulfed by Star
Astronomers have detected the longest gamma ray burst ever recorded, lasting approximately seven hours. The unprecedented event appears to have been caused by a black hole falling into and consuming a bloated star from the inside out.
Unprecedented Cosmic Event Detected
On July 2, 2025, NASA’s Fermi Gamma-ray Burst Monitor captured signals that would lead to the discovery of the longest gamma ray burst ever recorded, according to reports from the scientific community. When scientists combined this data with signals from multiple other instruments, including the Einstein Probe Wide-field X-ray Telescope and the Russian gamma-ray spectrometer Konus-Wind, they found they were dealing with an event lasting approximately 25,000 seconds – nearly seven hours. The burst, designated GRB 250702B, surpassed the previous record-holder by 10,000 seconds, sources indicate.
