## In brief

- A Perspective in Nature Astronomy, published online 13 November 2026, reviews discoveries from the fourth LIGO–Virgo–KAGRA observing run.
- Gravitational waves have now been detected in the hundreds, giving access to a more diverse population of merging black hole binaries.

## Why it matters

The larger sample of detected black hole mergers gives researchers a broader base for studying how these binaries form and what they are like.
