From Forbes, Feb. 17, 2021: Fermilab scientist Don Lincoln contextualizes the accomplishment of researchers working at the Japan Proton Accelerator Research Complex, or J-PARC. They have made an atomic nucleus that contains an unstable particle called the hyperon, or cascade particle. This could help in understanding neutron stars.

Scientists at CERN have found a way to learn more about the interior of neutron stars using the Large Hadron Collider. Researchers on the ALICE experiment are uncovering the properties of elusive hyperon particles hypothesized to be found inside neutron stars.
