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 ...

The Madison, Wisconsin-based startup Phoenix has scouted a team of nuclear elites for a new frontier: small reactors that can revolutionize medical imaging, munitions scanning, and even ...

Testing basic principles of particle physics does not necessarily require a high-energy accelerator. As Peter Geltenbort explains, a growing community of neutron scientists is probing similarly ...

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 ...
