Deep observations of two X-ray bright clusters of galaxies with ESA's XMM-Newton satellite allowed a group of international astronomers to measure their chemical composition with an unprecedented ...

A sudden blast of gamma rays that swept past Earth in December 2004 is helping solve one of astrophysics’ biggest mysteries: where the universe’s heaviest elements—like gold and platinum—come from. At ...

(Nanowerk News) The slow neutron-capture process (the s-process) is one of the nucleosynthesis processes that occurs in stars. It results in about half of the elements heavier than iron in the ...

Billions of light years away in a remote part of the universe, two neutron stars – the ultradense remnants of dead stars – collided. The catastropic cosmic event sent light and particles, including a ...

Astronomers have discovered an exceptionally rare star that may help to solve one of astronomy's enduring mysteries: where the universe's heaviest elements came from. The star, named LAMOST J0804+5740 ...

Study of some processes of nucleosynthesis in the evolving galaxy / A.K. Lavrukhina and R.I. Kuznetsova -- Some long-lived and stable nuclides produced by nuclear reactions / R. Gensho [and others] -- ...

Bits of the stars are all around us, and in us, too. About half of the abundance of elements heavier than iron originates in some of the most violent explosions in the cosmos. As the universe churns ...

Nobel Prize-winning physicist Frank Wilczek explores the secrets of the cosmos. Read previous columns here. Recent work observing gravitational waves seems to fill a big gap in our understanding of ...
