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

Billions of light years away in a remote part of the universe, two neutron stars – the ultradense remnants of dead stars – collided. The catastropic cosmic event sent light and particles, including a ...

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 ...

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

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

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

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

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 ...

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 ...
