The catalog of gravitational waves "heard" by LIGO, KAGRA and Virgo has doubled with detections of spacetime ripples.

University of Oregon astronomer Yvette Cendes made a surprising discovery years after a black hole shredded a star. What is ...

The results reveal that our universe is reverberating with cosmic collisions. Some of the waves stem from pairs of black ...

Astronomers have used the LOFAR telescope array to create the largest radio survey of the cosmos, revealing 13.7 million ...

Ripples in the fabric of space-time called gravitational waves may be the key to solving the Hubble tension — one of the biggest nagging problems in physics.

Mysterious “little red dots” spotted by the James Webb Space Telescope may not hide black holes after all. Scientists now ...

A ‘runaway’ black hole ejected from its host galaxy is barrelling across space — and leaving behind a wake of newborn stars. A 2023 paper 1 reported the discovery of a bright, straight feature that ...

Like physics, math has its own set of “fundamental particles”—the prime numbers, which can’t be broken down into smaller ...

At the heart of nearly every galaxy lurks a cosmic giant: a supermassive black hole. These mysterious objects, millions to billions of times more massive than our Sun, exert such powerful gravity that ...

For the first time, astronomers have spotted a middleweight black hole in the nearby universe. The discovery could help solve the riddle of how even heftier black holes form and grow up with their ...

Every galaxy has a supermassive black hole at its center, much like every egg has a yolk. But sometimes, hens lay eggs with two yolks. In a similar way, astrophysicists like us who study supermassive ...
