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 double blast of dying stars may be the first observed case of a long-hypothesized, never proven “superkilonova.” Although astronomers are still searching for concrete answers, a study published in ...

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

Imagine waking up one morning to find our Sun replaced by a cosmic powerhouse far stranger than anything we have seen. From giants that could swallow planets whole to stars so dense they bend reality, ...

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

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 ...

A puzzling cosmic blast detected in both light and gravitational waves may hint at a previously unseen type of explosion, ...

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 ...

Europium, one of the least-common elements in the universe, is found in TVs, lasers, and banknotes. Most of it was probably created by colliding neutron stars.

Neutron stars are formed when giant stars run out of fuel. Their internal pressure is no longer sufficient to fight gravity, and the resulting collapse and supernova explosion leaves a tiny core, with ...
