Neutron stars, the remnants of massive stars after a supernova, are among the densest and most fascinating objects in the universe. Recent discoveries have indicated that some neutron stars are ...

The study shows how some stars churn out heavy elements with no roadblock.

A newly analyzed gravitational-wave event has revealed something unexpected about one of the Universe’s most violent ...

Neutron stars are formed when giant stars run out of fuel. Their internal pressure is no longer sufficient to fight gravity, and the resulting collapse and supernova explosion leaves a tiny core, with ...

Artist’s impression of the powerful winds blowing from the bright X-ray source GX13+1. The X-rays are coming from a disc of hot matter, known as an accretion disc, that is gradually spiralling down to ...

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 ...

All around us are elements forged in stars, from the nickel and copper in coins to the gold and silver in jewelry. Scientists have a good understanding of how these elements form: In many cases, a ...

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. The ...
