Extraterrestrial organic matter that fell on Earth 3.3 billion years ago

The meteorites bring it regularly, but it has left no trace of it. It has been identified and analyzed by researchers from the CNRS, Chimie ParisTech, the Universities of Tours and Lille. Their publication, in the journal Geochimica and Cosmochimica Acta, offers a first model to distinguish these molecules from elsewhere from those produced on Earth.
