Space is an endless void of mysterious unknowns, and one particularly alluring enigma concerns the point at which neutron stars take on too much mass and collapse into black holes as a result.

Protons in neutron-rich nuclei have a higher average energy than previously thought, according to a new analysis of electron scattering data that was first collected in 2004. The research appears to ...

Right at the brink of a black hole, gravity twists space and time so violently that ordinary physics starts to fall apart.

The collision of two neutron stars around 130 million light-years from Earth, and the unique physics this merger created, may have shed new light on dark matter. Axions have never been directly ...

Neutron stars explained through stellar remnants and collapsed stars, revealing extreme density, gravity, magnetism, and ...

Fundamental questions that particle physicists have pondered for decades might be answered when a $9.2 million neutron physics beam line is built at the Department of Energy’s Spallation Neutron ...

Parity violation in neutron physics represents a subtle but fundamentally important deviation from mirror symmetry in nuclear interactions. This phenomenon arises from the interplay between the weak ...

So what are ultracold neutrons? Peter Geltenbort: The “thermal neutrons” produced by a research reactor such as ILL have energies of a few hundredths of an electron volt. On average they travel at ...

A new theory suggests fusion reactors could help scientists search for axions, mysterious particles that may explain dark ...

Astrophysicists have found evidence of a strange substance called quark matter at the heart of compact stars. Combining recent theoretical calculations with measurements of gravitational waves from ...

A research team at the Facility for Rare Isotope Beams (FRIB) is the first ever to observe a beta-delayed neutron emission ...
