The Cosmic Origins of Silver and Gold

  Heidelberg scientist shows that silver and gold materialized in different stellar explosions. At the end of their lives, stars with ten times the mass of our Sun explode as so-called supernovae. In the process, elements like silver are either hurled out into the Universe or produced in the first place. The illustration is an artist’s impression [continue reading]

The Brightest Stars Have a Close Companion

A new study using the European Southern Observatory’s (ESO) Very Large Telescope (VLT) has shown that most very bright high-mass stars, which drive the evolution of galaxies, do not live alone. Almost three-quarters of these stars are found to have a close companion star, far more than previously thought. Surprisingly most of these pairs are [continue reading]
