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

Astronomers may have discovered the first example of an explosive cosmic event called a "superkilonova," in the form of a gravitational wave signal detected on Aug. 18, 2025.

A double blast of dying stars may be the first observed case of a long-hypothesized, never proven “superkilonova.” Although astronomers are still searching for concrete answers, a study published in ...

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 ...

Neutron stars explained through stellar remnants and collapsed stars, revealing extreme density, gravity, magnetism, and ...

Neutron stars, the collapsed remnants of massive stars, hold the densest matter in the universe. These cosmic objects are ...

Delve into the enigmatic realm of neutron stars—stellar remnants that defy our conventional understanding. Once blazing stars ...

The field of astrophysics continues to probe the extreme regimes of matter and gravity through studies of neutron stars and black holes. These compact objects, forged in the aftermath of stellar ...

Astronomers have used a range of telescopes, including Hubble, to watch as particles dance around a neutron star collision that created the smallest black hole ever seen. When you purchase through ...
