Scientists have detected alien sugars in Earth-bound meteorites for the first time, providing further evidence that the ingredients needed to kick start life on our planet may have been delivered from space.
The boffins – led by a team at Tohoku University, Japan – analysed powdered samples of two meteorites dubbed NWA 801 and Murchison. They found several different types of sugars, including ribose – a vital component for RNA – in varying abundances that ranged from 2.3 to 180 parts per billion.
