The catastrophic collision of a black hole and a neutron star sent ripples across the universe. New analysis of those ripples ...

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 ...

Some neutron stars may contain a "special type of matter," according to a new NASA study. These observations from NASA's Chandra X-ray Observatory indicate that the interiors of neutron stars might ...

A powerful "gamma-ray burst" has been seen exploding from merging neutron stars hidden within a previously unknown mini-galaxy leftover from an ancient cosmic crash. The "collision within a collision" ...

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

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 ...

When certain large stars use up all their nuclear fuel and die, they collapse and detonate, creating a supernova. These end-of-life events are some of the most energetic in the universe, and send ...

Using NASA’s Swift satellite, McGill University and Penn State University astronomers have identified an object that is likely one of the closest neutron stars to Earth — and possibly the closest. The ...
