Neutron stars are massive gravitational monsters, and orbiting one wouldn't end up well for our planet. But what if we took ...

The blast may have been a kilonova — a type of neutron star merger — in the wake of a more traditional supernova.

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, ...

"We do not know with certainty that we found a superkilonova, but the event nevertheless is eye-opening." When you purchase through links on our site, we may earn an affiliate commission. Here’s how ...

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 ...

Using the joint Japan Aerospace Exploration Agency (JAXA), European Space Agency (ESA), and NASA X-Ray Imaging and Spectroscopy Mission (XRISM), scientists uncovered a dense but surprisingly slow wind ...

Astronomers tracked a decade of dramatic changes in P13, a neutron star undergoing supercritical accretion. Its X-ray luminosity rose and fell by factors of hundreds while its rotation rate ...

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 ...
