Scientists have named two systems of colliding supermassive black holes after Lord of the Rings locations, Gondor and Rohan.

An international collaboration of astrophysicists that includes researchers from Yale has created and tested a detection ...

Scientists have named newly detected merging supermassive black holes after ’Lord of the Rings’ locations, using gravitational wave data and quasar observations to map their mergers.

As two supermassive black holes orbit toward each other, they send out gravitational waves that go from lower to higher ...

In my January 23, 2026, “The Universe” column, I wrote about some of the biggest bangs the universe has to offer: exploding stars, hiccupping magnetars, stellar disruptions and colliding black holes.

Researchers propose a new technique to identify supermassive black hole binaries through gravitational lensing causing ...

Supermassive black holes rarely travel alone. Most large galaxies hide one at the center, and when galaxies collide, the two ...

On November 23, 2023, a groundbreaking astronomical event unfolded as scientists from the LIGO-Virgo-KAGRA Collaboration detected the most massive black hole merger ever observed. The finding was ...

An unusual tidal disruption event spotted by astronomers may be the result of an elusive intermediate mass black hole ripping apart a star.

Ten years after scientists first detected gravitational waves emerging from two colliding black holes, the LIGO-Virgo-KAGRA collaboration, a research team that includes Columbia astronomy professor ...

Astronomers have found growing evidence that runaway black holes are hurtling through galaxies at extreme speeds, leaving ...

An eon ago, when only microbes dwelled on Earth, a pair of black holes some 1.3 billion light-years beyond the solar system spiraled toward each other until they crashed. The two became one big black ...
