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 ...

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

Astronomers are working to capture the first-ever video of a black hole — a groundbreaking effort that could shed light on how these enigmatic cosmic objects behave and offer clues about the origins ...

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

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.

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 ...

The black hole would have to be within 25 light years from Earth, and we haven’t seen one that close yet. That’s not stopping Cosimo Bambi.

A newly detected X-ray transient may reveal the first direct evidence of an intermediate-mass black hole consuming a white dwarf. A newly observed cosmic outburst is giving astronomers a rare glimpse ...

An artist's concept of a tidal disruption event (TDE), which happens when a star passes close to a supermassive black hole. The gravity of the black hole pulls material from the star and launches a ...
