A 12.7 Billion Years Old Galaxy Discovered

  More than 12 billion years ago a star exploded, ripping itself apart and blasting its remains outward in twin jets at nearly the speed of light. At its death it glowed so brightly that it outshone its entire galaxy by a million times. This brilliant flash traveled across space for 12.7 billion years to [continue reading]

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]
