Physicists at Goethe University in Frankfurt, Germany, have used supercomputer simulations to predict a specific ...

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

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

A newly analyzed gravitational-wave event has revealed something unexpected about one of the Universe’s most violent encounters. Scientists have found the first strong evidence that a black hole and a ...

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

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 ...

In 2020, astronomers discovered a violent cosmic event that has led them to rethink how extreme pairs of astronomical objects form. These pairs are capable of producing powerful cosmic collisions.

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

Neutron stars escape collapse into a black hole thanks to degeneracy pressure produced by their neutrons, which is able to fight the crushing force of gravity. What exactly lies at the heart of a ...

A neutron star and black hole were detected merging along an unusual oval orbit, challenging long-held theories about how these systems form.
