A recent measurement of a rapidly spinning neutron star has disproved what was regarded as a credible picture of the star’s center. The centers of neutron stars are stiff and not squishy. Neutron ...

Some of the densest objects in the universe are neutron stars. Neutron stars are the remnants of stellar cores left behind when a star has gone supernova. The only known objects denser than neutron ...

Neutron stars are made out of cold ultra-dense matter. How this matter behaves is one of the biggest mysteries in modern nuclear physics. Researchers developed a new method for measuring the radius of ...

Groundbreaking results show that neutron stars of different masses may have the same size — upending astrophysical models. In the known universe, there is nothing quite like a neutron star. Born from ...
