The blast may have been a kilonova — a type of neutron star merger — in the wake of a more traditional supernova.

Scientists have discovered a new way to probe the interiors of neutron stars by using gravitational waves to turn them into "cosmic tuning forks." The reverberations of such ripples in spacetime could ...

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 ...

Neutron stars are some of the weirdest cosmic objects, and the greatest mysteries lie deep in their hearts. Neutron stars' surface gravities are so intense that the largest "mountains" are only a few ...

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 ...

The field of astrophysics continues to probe the extreme regimes of matter and gravity through studies of neutron stars and black holes. These compact objects, forged in the aftermath of stellar ...

"Most of the external layers of a massive star are removed during the supernova, but some material falls back, making the neutron star spin faster." When you purchase through links on our site, we may ...

It weighs more than 2 times the mass of our sun, but is only 18 miles wide. Astronomers have discovered the "most massive neutron star ever measured," amassing to more than two times the mass of our ...

Astrophysicists are closing in on one of the strangest possibilities in stellar evolution, a compact remnant that might sit ...

A distant neutron star has abruptly erupted in brightness, surging to roughly one hundred times its usual output and leaving astronomers scrambling to explain what could drive such a violent change.
