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.

Astronomers analyzing the gravitational-wave event known as GW200105 report evidence that a black hole and neutron star ...

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

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 ...

On May 22, 2020, light from a titanic explosion deep in space reached Earth. The energy seen by astronomers told of the collision of a pair of neutron stars, creating a kilonova explosion. This event, ...

A fresh analysis of gravitational wave data from a 2020 collision between a black hole and a neutron star has produced the first measured evidence of an eccentric, oval-shaped orbit in this type of ...

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

All known atomic nuclei and therefore almost all visible matter consists of protons and neutrons, yet many of the properties of these omnipresent natural building blocks remain unknown. As an ...

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 ...

An international research team has measured neutron form factors with previously unattained precision. All known atomic nuclei and therefore almost all visible matter consists of protons and neutrons, ...
