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.

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 ...

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 ...

Astronomers have detected the most massive neutron star ever, and it almost shouldn't even exist. Neutron stars are the smallest in the universe, with a diameter comparable to the size of a city like ...

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 ...

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 ...

When two neutron stars collide, they unleash some of the most powerful forces in the universe, creating ripples in spacetime, ...

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 ...

In a bizarre gamma-ray space explosion whose light reached Earth in 2023, a team led by astronomer Run-Chao Chen of Nanjing ...
