An international team from China and Italy has reported a possible cosmic encore to the landmark 2017 multi-messenger discovery. In November 2024, the LIGO-Virgo-KAGRA observatories detected gravitational waves from a binary black hole merger, designated S241125n. Remarkably, just seconds later, satellites recorded a short gamma-ray burst (GRB) from the same region of the sky.
