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

Neutron stars, the remnants of massive stars after a supernova, are among the densest and most fascinating objects in the universe. Recent discoveries have indicated that some neutron stars are ...

Neutron stars are some of the weirdest cosmic objects, and the greatest mysteries lie deep in their hearts. Neutron stars' surface gravities are so intense that the largest "mountains" are only a few ...

A research team led by Caltech may have just discovered the first-ever superkilonova, a cosmic phenomenon in which a star explodes twice in violently different ways. Their analysis of a series of ...

Astronomers have spotted AT2025ulz, a rare dual explosion — a supernova and a kilonova — that may be the first-ever observed “superkilonova.” ...

Scientists have precisely measured two unstable atomic nuclei that play a crucial role in explosive X-ray bursts on neutron stars. The results reveal faster nuclear reactions than previously thought, ...

In this video I show you what happens when you try to get close to 1 drop of a neutron star. I tell you how a neutron star is ...

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 ...

Scientists reveal how two unstable nuclei trigger neutron star explosions and power intense X-ray bursts across the universe. This breakthrough in nuclear physics shows explosions on neutron stars.

Neutron stars—the dense remnants of massive stellar explosions—and their presence in X‐ray binaries serve as natural laboratories for extreme physics. In these systems, matter is transferred from a ...

Neutron stars escape collapse into a black hole thanks to degeneracy pressure produced by their neutrons, which is able to fight the crushing force of gravity. What exactly lies at the heart of a ...
