$1.38 million to pick 'large' pieces of supernova grit out of meteorite

Ernst K. Zinner, PhD, research professor of physics and earth and planetary sciences in Arts & Sciences has received a three-year, $1,380,000 grant from the National Aeronautics and Space Administration (NASA) 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.

The Murchison (CM2) meteorite fell in Victoria, Australia, on the 28th September, 1969.
A total mass of 100 kg was recovered.

A new scientific analysis of a meteorite that fell to earth over Murchison in 1969 suggests it is far more important than first thought and could unlock the chemistry of the universe.
The famous Murchison meteorite, which weighed more than 100 kg, crashed to earth on September 28, 1969.

Fragments of a chemically primitive meteorite that landed near Murchison, Australia, in 1969 have long been known to harbour a variety of interesting compounds, including dozens of amino acids. But as analytic techniques become more sophisticated, the Murchison meteorite continues to reveal even more diversity and complexity in the early solar system, and new work by a team of European researchers is no exception.

Scientists say they have confirmed that a meteorite that crashed into earth 40 years ago contains millions of different organic compounds.
It is thought the Murchison meteorite could be even older than the Sun.

A new technique used to analyse samples from a meteorite that hit Australia more than 40 years ago could help scientists understand more about the chemical complexity of the early solar system. Calculations suggest the meteorite carried with it millions of different organic compounds.

It now seems quite likely that life began with self-replicating RNA molecules. But under what conditions? New Zealand theoretical biologist David Penny is warming to the idea of a cold start.

Late on the morning of September 28, 1969, a piece of space rock sonic-boomed across the south-eastern Australia sky and broke up, scattering chunks of speckled, black rock across the rural landscape near the Victorian hamlet of Murchison. The famed Murchison meteorite, a rare carbonaceous chondrite, delivered to Earth a soup of organic ingredients, including proteogenic amino acids like glycine, alanine, and glutamic acid and uracil, one of the four bases that form RNA.

Präsolare Körner - vulgo "Sternenstaub" - ziehen nicht nur durchs All, sondern stecken auch im Inneren von Himmelskörpern, die diese Körner bei ihrer Bildung integriert haben - auch in unserer Erde. Ein internationales Forscherteam um Philipp Heck von der Universität Chicago und Rainer Wieler von der ETH Zürich hat sich an die Altersbestimmung von Präsolaren Körnern aus dem Meteoriten Murchison gemacht, der im Jahr 1969 in Australien auf die Erde gefallen war.Und stellte dabei fest, dass diese jünger sind als gedacht.

Planetary scientists have claimed that the interstellar stuff which became incorporated into the planets and life on Earth has younger cosmic roots than theories predict.
An international team, led by Chicago University, has based its findings on an analysis of 22 interstellar grains from the Murchison meteorite.
