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.

Volume rendering of density in a simulation of a binary neutron star merger. New research shows that neutrinos created in the hot interface between the merging stars can be briefly trapped and remain ...

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 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 ...

The cosmos has delivered a rare kind of fireworks display, and astronomers are racing to understand what it means. A strange double flash from a distant galaxy appears to show two neutron stars ...

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 ...
