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 ...

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 ...

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 ...

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

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