GW250114: Rotating Black Holes Collide
GW250114 was the strongest gravitational wave signal yet measured, detected by both arms of the Laser Interferometer Gravitational-wave Observatory, or LIGO.

The new larger black hole has a mass of around 63 solar masses, even though the event happened about a billion light years away.
