Organic compounds and water were found in two very old meteorites


They fell to Earth in Morocco and Texas in 1998 but at that time the technology did not exist to detect tiny amounts of amino acids. Researchers have examined the rocks again and been able to analyse the salt crystals that were found in both rocks. The discovery was made by an international team of researchers, which included scientists from the Open University (OU) in the UK and NASA’s Johnson Space Centre in Texas.

The scientists say the salt in the halite crystals may have originated from the dwarf planet Ceres, which is located between Mars and Jupiter in the asteroid belt. The study’s lead author Dr Queenie Chan, also said: “Each salt crystal, which is about two millimeters in size and the color of a blue sapphire, is essentially a little package full of organic compounds and the necessary building blocks of life. This discovery is important because the amino acids form the basis of proteins and hydrocarbons are organic compounds that are extremely common in living beings.
