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 ...

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 ...

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.

In 2020, astronomers discovered a violent cosmic event that has led them to rethink how extreme pairs of astronomical objects ...

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

Atoms are made of three things: protons, neutrons, and electrons. Electrons are a type of fundamental particle, but protons and neutrons are composite particles made of up and down quarks. Protons ...

Gold and other heavy elements are born in some of the universe’s most violent events—but scientists still struggle to ...

Neutron detection and analysis techniques form a critical toolkit in both fundamental research and practical applications across diverse fields. At the heart of these methods is the ability to probe ...

Scientists analyzing a gravitational-wave signal have discovered that a neutron star and black hole spiraled together on an ...
