Japan’s science ministry says more than 20 types of amino acid have been found in samples collected from the Ryugu asteroid. The discovery may help scientists better understand the origins of life, as amino acids are one of its basic building blocks.
The sand and dust samples were collected from the asteroid and brought to Earth by Japan’s Hayabusa2 space probe in 2020.
