The article reports on the discovery of researchers about organic materials preserved in a unique meteorite that were formed in distant reaches of the early solar system. The researchers, which are from the U.S. National Aeronautics and Space Administration's Johnson Space Center in Houston, Texas, have performed a study on the Tagish Lake carbonaceous chondrite, a rare type of meteorite rich is organic compounds. According to research leader Keiko Nakamura-Messenger, the Tagish Lake meteorite contains numerous submicrometer hollow organic globules. In addition, unusual hydrogen and nitrogen isotopic compositions have also been found in the meteorites, which prove that the globules did not come from Earth. Key information about the discovery are further discussed.

    Unusual amberine-coloured speleothems were recently found in El Soplao Cave (Cantabria, Spain). Chromophore elements such as Fe, Mn, Cd, Co or Ti were not present in significant quantities. Rather, our data show that their colour comes from leachates of fossilized organic material hosted in the...
