This video zooms in on the gamma-ray burst GRB 250702B, a powerful explosion that repeated several times over the course of a day on 2 July, an event unlike anything ever witnessed before. The event took place in another galaxy, but its cause remains unknown.
The video combines images taken with different telescopes at different times and various wavelengths. The journey begins with a wide-field view of the sky in visible light, which then switches to infrared light. The video ends with a sequence of infrared images taken with ESO’s Very Large Telescope showing the aftermath of the explosion, with the source fading from 3 July (one day after the explosion) to 15 July.
