Astrophysicists are closing in on one of the strangest possibilities in stellar evolution, a compact remnant that might sit ...

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 ...

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

This investigation explores the possibility that quark stars, an even denser form of stellar remnant than neutron stars, may ...

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

Scientists have precisely measured two unstable atomic nuclei that play a crucial role in explosive X-ray bursts on neutron ...

Scientists reveal how two unstable nuclei trigger neutron star explosions and power intense X-ray bursts across the universe.

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 ...

A superkilonova candidate event, named AT2025ulz, was observed in 2025; LIGO and Virgo first spotted gravitational waves, while the Zwicky Transient Facility was the first to detect light from the ...

Binary neutron star mergers emit gravitational waves followed by light. To fully exploit these observations and avoid missing key signals, speed is crucial. An interdisciplinary team of researchers ...

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 ...
