In a study published in The Astrophysical Journal, scientists have proposed the features of rapid neutron capture process (r-process) nucleosynthesis in a novel scenario, common envelope jet ...

All around us are elements forged in stars, from the nickel and copper in coins to the gold and silver in jewelry. Scientists have a good understanding of how these elements form: In many cases, a ...

Heavy duty: artist’s impression of a kilonova releasing r-process elements into the cosmos. (Courtesy: ESO/L Calçada/M Kornmesser) The mystery of where heavy elements such as gold and silver come from ...

For the first time, astronomers have definitively ID’d a specific heavy element forged by a neutron star merger. Theories of physics have long predicted that about half of the universe’s heavy ...

Violent explosions of massive, magnetized stars may forge most of the universe’s heavy elements, such as silver and uranium. The ancient star’s elements aren’t from the remnants of a neutron star ...

In an ejection that would have caused its rotation to slow, a magnetar is depicted losing material into space in this artist’s concept. The magnetar’s strong, twisted magnetic field lines (shown in ...

A: The lightest elements in the universe — hydrogen, helium, and a little lithium — were born shortly after the Big Bang. The heavier elements, up to iron, were forged later, in the hearts of stars ...

Up to a certain point, the elements of the periodic table are largely formed in the hearts of stars. But for elements that are heavy enough (heavier than zinc typically), fusing two lighter nuclei ...

Carl Sagan once famously said: “We are made of star stuff.” He was referring to the origin of many elements — like the calcium in our bones and the iron in our blood — that are forged in the last ...
