US EditionLIGO-Virgo-KAGRA Release Data on Record 225-Solar-Mass Black Hole Merger
UNITED STATES, JUL 14 – The merger formed a black hole 225 times the Sun's mass, challenging stellar evolution models and suggesting complex or hierarchical formation, researchers said.
- The LIGO-Virgo-KAGRA Collaboration detected a black hole merger with a mass of 225 times that of the sun, marking it as the most massive yet recorded.
- Previously, the largest black hole merger was 140 times the sun's mass, noted from an event in 2021 called GW190521.
- Gravitational waves are providing unique insights into the nature of black holes, highlighting their fundamental properties.
- The observation showcases advancements in instrumentation and data-analysis in gravitational-wave astronomy.

The merger created a black hole with a mass approximately 225 times that of the Sun. The most massive black hole merger ever observed by gravitational waves was detected by the LIGO observatory on November 23, 2023, as part of the three-observatory collaboration, LIGO-Virgo-KAGRA (LVK).
LIGO's heaviest black hole demands next-generation science
If you want to detect a gravitational wave, you have to design something extraordinary. Gravitational waves are ripples in spacetime — distortions in the very fabric of spacetime itself — that propagate at the speed of light and that alternately stretch/expand space in one dimension, perpendicular to the direction of the wave’s propagation, while compressing/shrinking space at a 90 angle to the expanded dimension. Even the strongest of these osc…
Gravitational shockwave: LIGO catches a 225-solar-mass black-hole smash-up
Gravitational-wave detectors have captured their biggest spectacle yet: two gargantuan, rapidly spinning black holes likely forged by earlier smash-ups fused into a 225-solar-mass titan, GW231123. The record-setting blast strains both the sensitivity of LIGO-Virgo-KAGRA and the boundaries of stellar-evolution theory, forcing scientists to rethink how such cosmic heavyweights arise.
