On August 17th, both the light and the gravitational wave signals from inspiraling-and-merging neutron stars reached Earth, where both were detected, for the first time, by humans. The inspiral phase ...

Most stars in our universe come in pairs. While our own sun is a loner, many stars like our sun orbit similar stars, while a host of other exotic pairings between stars and cosmic orbs pepper the ...

A neutron star is a superdense remnant of a massive sun. A star that holds at least 8 times the Sun’s mass will burn through its material much faster than the Sun will. This massive star will then die ...

A single teaspoon of material scooped from a neutron star would, if placed on Earth’s surface, weigh billions of tons. That ...

The core of a neutron star is such an extreme environment that physicists can’t agree on what happens inside. But a new space-based experiment — and a few more colliding neutron stars — should reveal ...

Nuclear puzzle: In the nucleus, neutrons can be stable, but free neutrons decay after a short period. Exactly how short is in dispute because experiments on neutrons stored in bottles and neutrons in ...

All of us probably know what neutrons are, or have at least heard of them back in physics class. Yet these little bundles of quarks are much more than just filler inside an atom’s nucleus. In addition ...

Neutrons are among the basic building blocks of matter. As long as they are part of a stable atomic nucleus, they can stay there for arbitrary periods of time. However, the situation is different for ...
