Known as “islands of inversion,” these regions are found among a sea of normal nuclei. Now, a new island may have been ...

All known atomic nuclei and therefore almost all visible matter consists of protons and neutrons, yet many of the properties of these omnipresent natural building blocks remain unknown. As an ...

An international research team has measured neutron form factors with previously unattained precision. All known atomic nuclei and therefore almost all visible matter consists of protons and neutrons, ...

The oscillating frequencies of two short gamma-ray bursts are the best evidence yet for the formation of 'impossible' hypermassive neutron stars that can briefly defy gravity before collapsing to form ...

When certain large stars use up all their nuclear fuel and die, they collapse and detonate, creating a supernova. These end-of-life events are some of the most energetic in the universe, and send ...

For hundreds of millions of years, a pair of neutron stars – the burned-out cores of once massive stars – spiraled closer and closer together until finally colliding in a tremendous explosion known as ...
