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.

Astronomers have discovered a bizarre carbon-rich planet orbiting a neutron star, PSR J2322-2650b, with soot clouds and ...

A double blast of dying stars may be the first observed case of a long-hypothesized, never proven “superkilonova.” Although ...

Neutron stars are what remain after giant stars collapse, leaving behind a body so dense that its core crushes protons and neutrons into a tightly packed soup. These objects cool very slowly over ...

A mysterious cosmic explosion linked to gravitational waves may reveal a previously unknown type of supernova event - a ...

Astronomers have discovered a carbon-rich exoplanet with a bizarre atmosphere and shape, orbiting a neutron star under extreme conditions that challenge current models of planetary formation. Scientis ...

Astronomers tracked a decade of dramatic changes in P13, a neutron star undergoing supercritical accretion. Its X-ray ...

In a strange turn of events, a supernova birthed twin baby neutron stars that merged to make a powerful kilonova.

A puzzling cosmic blast detected in both light and gravitational waves may hint at a previously unseen type of explosion, challenging astronomers to rethink how neutron stars are born and collide.

If you approached a neutron star, you would be instantly crushed by gravity and fried by X-rays, while your very atoms would be torn apart by magnetic fields and gravity – making you a splattered ...

New simulations of neutron star mergers reveal that the mixing and changing of tiny particles called neutrinos impacts how the merger unfolds, including the composition and structure of the merger ...
