In Euclid's deep fields, stars flare up that were not in any catalog. A telescope built to map dark matter has worked like a camera trap: one frame, and a cosmic explosion is already on record.

On the night of August 18, 2025, the SVOM space telescope detected a short gamma-ray burst — a powerful flash of energy lasting less than two seconds. Such bursts are usually linked to mergers of neutron stars, the ultra-dense remnants of dead stars.
