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 ...

Astrophysicists are starting to treat a strange class of “undead” suns as potential tools rather than mere curiosities, ...

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

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

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 ...

Gold, uranium, and other heavy elements on Earth did not form here. They were born in the violent deaths of massive stars and ...

Learn about what may be the first ever superkilonova ever observed, emitting gravitational waves that hint at the collision of two dead 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 ...
