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 ...

"It is fascinating to concretely see how each new neutron-star observation enables us to deduce the properties of neutron-star matter with increasing precision." When you purchase through links on our ...

Artist’s impression of the different layers inside a massive neutron star, with the red circle representing a sizable quark-matter core. New theoretical analysis places the likelihood of massive ...

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 ...

Some neutron stars probably have something strange lurking in their cores, according to a recent study. Neutron stars are already some of the most peculiar objects in the universe. They contain enough ...

For hundreds of millions of years, a pair of neutron stars – the burned-out cores of once massive stars – spiraled closer and closer together until finally colliding in a tremendous explosion known as ...

New theoretical analysis places the likelihood of massive neutron stars hiding cores of deconfined quark matter between 80 and 90 percent. The result was reached through massive supercomputer runs ...
