Mergers between two neutron stars have produced more heavy elements in last 2.5 billion years than mergers between neutron stars and black holes.

When a black hole eats a star, it produces a "tidal disruption event" that can outshine the light of every star in the host galaxy for months or even years

Researchers have detected, for the first time, light from the back side of a black hole. The finding fulfills a prediction from Einstein's work.

Math explains how light curving around black holes can reveal multiple images of the same galaxies to observers, according to a new study.

Study offers evidence, based on gravitational waves, to show that the total area of a black hole’s event horizon can never decrease.

The aftermath of a black hole colliding with a neutron star has been recorded on Earth.

Gravitatational-wave signals suggest black holes completely devoured their companion neutron stars.

Regardless of size, all black holes experience similar accretion cycles, a new study finds.

Certain ultralight bosons would be expected to put the brakes on black holes, but new results show no such slowdown.
