Have you ever wondered what would happen if you tried to build an object made entirely of neutrons? Imagine a neutron tennis ...

What happens if you keep stacking neutrons until gravity itself takes control? Neutrons, the silent stabilizers inside atomic nuclei, seem perfect for building matter since they don’t repel like ...

Just as Baade and Zwicky predicted, neutron stars are incredibly small. The average neutron star has a diameter of roughly 12.5 miles (20 kilometers), or about the size of a city.

Normally, any free neutrons decay in roughly 15 minutes. But the intense confines of the neutron star's interior keep the neutrons stable and free-flowing.

Just a sugar cube's worth of neutron star material would have a mass of 100 million tons on Earth, according to a statement released Monday by the Green Bank Observatory.

Neutron stars are the classic example of a synthesis between quantum mechanics and gravity. Formed after the collapse of the remnants of a supernova, a neutron star is generally smaller than the ...

Neutron stars, when they merge, should create an electromagnetic counterpart if they don't create a black hole right away, as light and particles will be expelled due to internal reactions in the ...

Astronomers witnessed for the first time ever a rare collision of two dense neutron stars. The discovery began with an instrument called LIGO, which won this year’s Nobel Prize for its discovery ...

"It would be truly amazing if the good old neutron turned out to be the particle enabling us to probe the dark matter sector of the universe," said study lead author Bartosz Fornal, a theoretical ...
