The catalog of gravitational waves "heard" by LIGO, KAGRA and Virgo has doubled with detections of spacetime ripples.

Neutron stars harbor some of the most extreme environments in the universe: their densities soar to several times those of ...

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 ...

Add Yahoo as a preferred source to see more of our stories on Google. This artist's concepts shows a hypothesized event known as a superkilonova. A massive star explodes in a supernova (left), which ...

Astronomers suspect the heart of the Milky Way may be hiding a big secret: a rapidly spinning, highly magnetic, neutron ...

Neutron stars are massive gravitational monsters, and orbiting one wouldn't end up well for our planet. But what if we took just a spoonful of it and transported it to Earth? Such a tiny amount of a ...

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 ...

Scientists report a possible pulsar at the Milky Way’s center, discovered through radio observations by the Breakthrough Listen team using the Green Bank Telescope, offering a new laboratory for ...

In the depths of the universe, where black holes collide and neutron stars crash, invisible ripples in spacetime are sent across the cosmos, carrying with them secrets about the most extreme events in ...
