Two meteorites crashed to our planet in 1998 after billions of years in the asteroid belt. And they had something in common besides reaching Earth the same year: they were the first meteorites we’ve found to have both complex organic compounds like amino acids and hydrocarbons, and liquid water. They may have come from the asteroid Hebe and the dwarf planet Ceres. Around 20 years after the two meteorites – Zag and Monahans – plummeted to Earth, landing in Texas and Morocco, laboratory equipment is powerful enough to scrutinize blue salt crystals on the meteorites, according to The Open University.
