Earth's Oldest Solid Material
Has Been Discovered Scientists say it is stardust from a meteorite found in Australia
half a century ago. Their findings have been published in 'Proceedings of the National Academy of Sciences.' The presolar grains in the
meteorite are said to be up
to seven billion years old. That would make them
older than the sun. For around three decades, the material has been analyzed at
the University of Chicago. Researchers add that the material's origins point to a "star baby boom." The Field Museum also says that only 5 percent of discovered meteorites contain this type of stardust. Lead author Philipp Heck, via 'USA Today'
