A neutron star compresses more mass than the Sun into a sphere roughly the size of a city. That extraordinary compactness ...

A neutron star is so dense that one sugar cube of its material would weigh around 1 trillion kilograms.

Atoms are made of three things: protons, neutrons, and electrons. Electrons are a type of fundamental particle, but protons and neutrons are composite particles made of up and down quarks. Protons ...

Add Yahoo as a preferred source to see more of our stories on Google. An illustration of two ice-blue orbs smashing together, surrounded by warm reddish dust and gas. The collision of two neutron ...

A new simulation created using a NASA supercomputer has shown how things get messy for merging neutron stars even before they slam together; their magnetospheres, the most powerful magnetic fields in ...

The dense remains of massive stars generate powerful jets of gas and dust that move hundreds of millions of miles per hour, according to research published last week in Nature. When some massive stars ...

Where do gold, platinum and uranium come from? This question has fascinated astrophysicists and nuclear physicists for ...

Physicists have shown that extremely light particles known as axions may occur in large clouds around neutron stars. These axions could form an explanation for the elusive dark matter that ...

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 ...

Forget archaeologists and their lost civilizations, or paleontologists with their fossils—astrophysicist Heloise Stevance studies the past on an entirely different scale. When astronomers catch a ...

idea may explain why some neutron stars emit mysterious flickering X-rays. Neutron stars are the collapsed cores of massive stars. They pack roughly one-and-a-half times the mass of our Sun into a ...
