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

For years, quark stars were only theory, a step beyond neutron stars in the collapse of matter. Now, new signals hint these ...

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 ...

A superkilonova candidate event, named AT2025ulz, was observed in 2025; LIGO and Virgo first spotted gravitational waves, ...

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 ...
