ESA's XMM-Newton and NASA's Chandra spacecraft have detected three young neutron stars that are unusually cold for their age. By comparing their properties to different neutron star models, scientists ...

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 ...

Matching the neutron stars' cooling rates to their equation of state could help scientists figure out a quantum theory of gravity. When you purchase through links on our site, we may earn an affiliate ...
