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 ...

Physicists have shown that extremely light particles known as axions may occur in large clouds around neutron stars. These axions could form an explanation for the elusive dark matter that ...

Neutron stars, the remnants of massive stars after a supernova, are among the densest and most fascinating objects in the universe. Recent discoveries have indicated that some neutron stars are ...

New research in our Milky Way has revealed a neutron star that rotates around its axis at an extremely high speed. It spins 716 times per second, making it one of the fastest-spinning objects ever ...

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.

Add Yahoo as a preferred source to see more of our stories on Google. This artist's concepts shows a hypothesized event known as a superkilonova. A massive star explodes in a supernova (left), which ...

Neutron stars are so named because in the simplest of models they are made of neutrons. They form when the core of a large star collapses, and the weight of gravity causes atoms to collapse. Electrons ...

Neutron stars are ultra-dense star remnants made up primarily of nucleons (i.e., protons and neutrons). Over the course of millions of years, these stars progressively cool down, radiating heat into ...

It's not science fiction: Scientists have discovered a neutron star that spins faster than any blender humans have ever made. In a recently published study, scientists discovered that the 4U 1820-30 ...

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 ...
