Since the Big Bang, the early Universe had hydrogen, helium, and a scant amount of lithium. Later, some heavier elements, including iron, were forged in...
High-energy photons produced deep in gamma-ray burst jets emerging from a collapsed star could dissolve the outer stellar layers into free neutrons, causing...
Ultrahigh energy cosmic rays are the highest-energy particles in the Universe, whose energies are more than a million times what can be achieved by humans.
Professor...
The rapid neutron capture process, or the so-called r-process, occurs in neutron-rich environments such as neutron star mergers or certain types of supernovae....
An explosion of a fast-spinning strongly magnetized star, called a magneto-rotational hypernova, is the most likely explanation for the presence of unusually...
The thermal evolution of rocky planets depends on the heat input from three long-lived radiogenic elements: potassium, thorium, and uranium. Concentrations...
Astronomers using ESO’s Very Large Telescope (VLT) have detected a freshly made heavy element, strontium, in the aftermath of GW170817, a merger of two...
According to new research, a nearby binary neutron-star merger gave birth to 0.3% of the Earth’s heaviest elements, including gold, platinum and uranium;...
Origin of Universe’s heavy elements, ranging from gold to uranium, has finally been confirmed, after a gravitational wave source was seen and heard for...
In a paper to be published in the journal Physical Review Letters (arXiv.org preprint), Professor George Fuller of the University of California, San Diego,...
