As binary neutron stars spiral around each other to merge, their gravitational tidal forces distort each other's shape and ...

Merging black holes and neutron stars have unusual oval orbits prior to colliding and merging, which challenge the laws of ...

Scientists analyzing a gravitational-wave signal have discovered that a neutron star and black hole spiraled together on an oval-shaped orbit just before merging. This unusual motion, detected in the ...

A research team is using astrophysical explosions to understand the mysterious forces at work in some of the smallest ...

Scientists may soon see inside neutron stars, potentially revealing a state of matter, quark-gluon plasma, last seen immediately after the Big Bang.

Astronomers have tracked a powerful blast of radiation back to its source, finding a neutron star collision within colliding galaxies.

Astronomers analyzing the gravitational-wave signal from a 2020 collision between a black hole and a neutron star report ...

Neutron stars harbor some of the most extreme environments in the universe: their densities soar to several times those of ...

Some of the universe’s densest objects can twist, stretch, and resonate in ways that challenge even the most seasoned ...

The catastrophic collision of a black hole and a neutron star sent ripples across the universe. New analysis of those ripples could upend a major theory about how these extreme pairs form.

Scientists believe this long stream of gas may have formed when several galaxies collided millions of years ago.
