Merging black holes and neutron stars have unusual oval orbits prior to colliding and merging, which challenge the laws of ...

As binary neutron stars spiral around each other to merge, their gravitational tidal forces distort each other's shape and ...

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.

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 ...

Breakthrough discovery provides new clues about how these celestial bodies - that push the known laws of physics to their limits - find each other.

Artist’s impression of an eccentric neutron star–black hole binary. The neutron star’s path is shown in blue and the black hole’s motion in orange as the two objects orbit each other. The eccentricity ...

Using NASA’s Chandra X-ray Observatory and other telescopes, astronomers have traced a short-duration gamma-ray burst event called GRB 230906A to a faint dwarf galaxy embedded in a vast stream of ...

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

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 fleet of NASA missions has likely uncovered a collision between two ultradense stars in a tiny galaxy buried in a huge ...

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 ...
