The elements above iron on the periodic table are thought to be created in cataclysmic explosions like the merger of two neutron stars or in rare classes of supernovae. New research suggests fission may operate in the cosmos during the creation of the heavy elements. Combing through data on a variety of elements that reside in very old stars, researchers have found a potential signature of fission, indicating that nature is likely to produce superheavy nuclei beyond the heaviest elements on the periodic table.

When in a Plasma of Quarks and Gluons, Not All Jets Radiate Equally
Department of Energy, Office of Science

Colliding nuclei at high speeds melts their constituent quarks and gluons into a Quark-Gluon Plasma (QGP). Quarks and gluons from the colliding nuclei also sometimes ricochet off one another very early on in the collision and form sprays of energetic particles known as jets. These jets lose their energy as they exit the plasma, with wide jets losing more energy than narrow jets. Researchers have confirmed that the plasma treats each prong of a jet independently only when the prongs are separated by a sufficiently large angle.
