The international LIGO-Virgo-KAGRA Collaboration reports the observations of two record-breaking events in gravitational wave observations. They were detected in October and November 2024, and they might be a crucial step forward in our understanding of the ripples in space-time and the events that create them.

In the 10 years since the first detection of gravitational waves, we have detected hundreds of these waves produced by the collisions between very dense objects, either neutron stars or black holes. These two new observations might represent a paradigm shift in what’s out there.

GW241011 was detected on October 11, 2024. It was the collision between two black holes around 17 and
