LIGO scientists say they have discovered gravitational waves coming from another black hole merger, and it’s the tiniest one they’ve ever seen.

The findings, submitted to the Astrophysical Journal Letters, could shed light on the diversity of the black hole population — and may help scientists figure out why larger black holes appear to behave a little differently from the smaller ones.
