Obituary: Ernst K. Zinner, astrophysicist and cosmochemist, 78
Ernst K. Zinner, PhD, research professor emeritus of physics and earth and planetary sciences in Arts & Sciences at Washington University in St. Louis, died Thursday, July 30, of medical complications of mantle cell lymphoma. Among many other accomplishments, in 1987 Zinner identified for the first time material in the laboratory that predated the formation of the solar system 4.6 billion years ago.
$1.38 million to pick ‘large’ pieces of supernova grit out of meteorite
Ernst K. Zinner, research professor of physics and of earth and planetary sciences, both in Arts & Sciences at Washington University in St. Louis, has received a three-year, $1,380,000 grant from the National Aeronautics and Space Administration to study presolar grains in a sample of the Murchison meteorite, a primitive meteorite that fell to Earth near the town of Murchison, Australia, in 1969. Presolar grains are literally tiny bits of stars — stardust — that were born and died billions of years ago, before the formation of the solar system. Some carry within them clues to the process of nucleosynthesis by which new elements are forged in the bellies of supernovae.
