Neutron stars explained through stellar remnants and collapsed stars, revealing extreme density, gravity, magnetism, and ...

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

It weighs more than 2 times the mass of our sun, but is only 18 miles wide. Astronomers have discovered the "most massive neutron star ever measured," amassing to more than two times the mass of our ...

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

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.

Astrophysicists are turning the universe’s dying stars into laboratories for one of physics’ most elusive ideas, the axion.

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

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 ...

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 ...

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 ...
