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

The universe may contain extremely dense and exotic hypothetical cosmic objects known as strange quark stars. While astrophysicists continue to debate quark stars' existence, a team of physicists has ...

On May 22, 2020, light from a titanic explosion deep in space reached Earth. The energy seen by astronomers told of the collision of a pair of neutron stars, creating a kilonova explosion. This event, ...

Neutron stars explained through the final moments of massive stars reveal some of the most extreme objects in the universe. When stars between eight and twenty times the Sun's mass exhaust their ...

The cosmos has delivered a rare kind of fireworks display, and astronomers are racing to understand what it means. A strange double flash from a distant galaxy appears to show two neutron stars ...

Neutron collisions are cosmic events of immense power that have the ability to forge some of the universe’s most precious elements, including gold. These astronomical phenomena provide a unique ...

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 ...

One of the confirmed cosmic sources for gold is the neutron star merger (or neutron star collision). This is an event where two neutron stars end up in the same orbit and eventually lose energy and ...
