How are heavy elements formed in the universe? Extremely neutron-rich atomic nuclei and their beta-decay rates play an ...

The formation of small worlds like Earth previously was thought to occur mostly around stars rich in heavy elements such as iron and silicon. However, new ground-based observations, combined with data ...

Researchers at the Argonne National Laboratory studied a nuclear reaction and measured conditions that can explain how heavy elements are formed inside stars. Stars are mainly composed of light ...

For much of the twentieth century, scientists believed that the heaviest naturally occurring elements formed primarily inside stars. Over the past two decades, astronomical observations and laboratory ...

For the first time, a freshly made heavy element, strontium, has been detected in space, in the aftermath of a merger of two neutron stars. This finding was observed by ESO’s X-shooter spectrograph on ...

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 ...
