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

Neutron stars harbor some of the most extreme environments in the universe: their densities soar to several times those of ...

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 ...

Scientists have uncovered the first robust evidence of a black hole and neutron star crashing together but orbiting in an ...

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 ...

Astronomers suspect the heart of the Milky Way may be hiding a big secret: a rapidly spinning, highly magnetic, neutron ...

A research team is using astrophysical explosions to understand the mysterious forces at work in some of the smallest building blocks in nature: atomic nuclei. In new research published in Nature ...

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 ...

Neutron stars—the dense remnants of massive stellar explosions—and their presence in X‐ray binaries serve as natural laboratories for extreme physics. In these systems, matter is transferred from a ...
