For the first time, scientists have detected a newly born heavy element in space, forged in the aftermath of a collision between a pair of dead stars known as neutron stars. The findings shed light on how the universe's heaviest elements are created, providing a missing piece of the puzzle...

The chemical evolution of the Universe is governed by the nucleosynthesis contribution from stars, which in turn is determined primarily by the initial stellar mass. The heaviest elements are primarily produced through neutron capture nucleosynthesis. Two main neutron capture processes identified are the ...
In this physical scenario, the high-energy quark-gluon plasma sea was first created in a transient quark-gluon epoch right after the big bang, and within next few minutes, the mass majority of the lightest three elements, hydrogen, helium and lithium, were created by the so-called primordial...
level to penetrate into the nuclei shells of the atoms lie within the vary center of the planetary embryos, which could create a group of ultra-heavy mega-nuclear elements (UMNEs)—a group of extremely yet-known heavy elements that could be million times heavier that the heaviest known ...

The synthesis and the properties of the heaviest elements are the subject of this paper. All of the elements above seaborgium (Z=106) have been identified on the basis of single-atom decays after separation in-flight. These elements cover a region of deformed shell nuclei connecting the element...
In July 2012, the ATLAS and CMS collaborations at the CERN Large Hadron Collider announced the observation of a Higgs boson at a mass of around 125 gigaelectronvolts. Ten years later, and with the data corresponding to the production of a 30-times lar
