Machine learning and state-of-the-art supernova nucleosynthesis has helped researchers find that the majority of observed second-generation stars in the universe were enriched by multiple supernovae.

This creation of the elements, called nucleosynthesis, is what got Woosley interested in supernovae in the first place. Starting as a graduate student at Rice University in the 1960s, Woosley spent ...

Ion probe studies and improved stellar nucleosynthesis models are providing new insights into our solar system's stardust. Until recently, cosmochemists and astrophysicists assumed that supernovae and ...

By using machine learning and state-of-the-art supernova nucleosynthesis, a team of researchers have found the majority of observed second-generation stars in the universe were enriched by ...

An unusual star system created more of a fizz and less of a bang when it exploded in a supernova. The “ultra-stripped” supernova led researchers to discover the two stars 11,000 light-years ...

This process of ‘nucleosynthesis’ leads to the emission of gamma rays, which easily reach us from all regions of our galaxy. ESA’s Integral observatory has been measuring such gamma rays ...

This new supernova has appeared in a galaxy — a star city — beyond our own. The galaxy is known as the Pinwheel Galaxy, (also designated as Messier 101, or M101) and is a large, loosely wound ...

A supernova’s delayed reappearance could pin down how fast the universe expands. The catch: We have to wait until about 2037 for an answer. This cluster of galaxies, ...

The supernova, named SN 2023ixf, is located 21 million light-years away. It should remain visible with the aid of a telescope for at least a few months, astronomers said.

A sparkling new supernova has appeared in the night sky, and a telescope atop Mauna Kea in Hawaii was perfectly poised to capture the aftermath of the cosmic burst.
