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

One such superkilonova candidate event, named AT2025ulz, was observed in 2025; LIGO and Virgo first spotted gravitational ...

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

Astronomers report a strange cosmic blast that looked like a kilonova, then behaved like a supernova, hinting at a possible first “superkilonova” and leaving scientists debating how stars truly die.

But it takes the collision of two neutron stars — incredibly dense stellar corpses — to create the heavier elements like silver, gold, and platinum. Neutron stars aren’t just notable for the valuable ...

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 ...

It isn’t a secret that humanity and everything around us is made of star stuff. But not all stars create elements equally. Sure, regular stars can create the basic elements: helium, carbon, neon, ...
