Black Holes

Voracious supermassive black holes light up the cores of “active” galaxies across the universe. How we see them, however, is a matter of perspective

A controversial prediction about black holes and the expansion force of the universe could explain a cosmology mystery

Gauging the mass of a black hole is tricky, but astronomers have devised multiple methods to measure the heft of these galactic gluttons

Spacetime ripples from a black hole collision across the cosmos have confirmed weird aspects of black hole physics

Some black holes get extremely massive. Is there an upper limit to their growth?

JWST observations of light sources before the first galaxies should have formed are raising new questions about our galactic origins

Scientists are uncovering how spinning black holes launch jets, warp spacetime and shape the cosmos

After 10 years of gravitational-wave research, the LIGO Lab team at MIT is getting ready for the next generation of detectors.

A U.S. gravitational wave detector spotted a collision between fast-spinning “forbidden” black holes that challenge physics models

After black holes devour stars, sometimes the feast comes back up

Some stars streaking through the Milky Way at millions of kilometers per hour probably trace back to a supermassive black hole in a neighboring galaxy

Researchers have shown that abstract mathematical functions from the frontiers of theoretical physics have a real-world use in modeling gravitational waves
