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

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 ...

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 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 ...

The cosmos has delivered a rare kind of fireworks display, and astronomers are racing to understand what it means. A strange double flash from a distant galaxy appears to show two neutron stars ...

"Most of the external layers of a massive star are removed during the supernova, but some material falls back, making the neutron star spin faster." When you purchase through links on our site, we may ...

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 ...

An international team of scientists has modeled the formation and evolution of the strongest magnetic fields in the universe. The team used advanced numerical simulations to model the magneto-thermal ...

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 ...
