The discovery of all five nucleobases on Ryugu strengthens the idea that life’s molecular ingredients formed in space before reaching Earth. A new study reports that samples from the asteroid Ryugu contain all five fundamental nucleobases, the molecular “letters” of life. Tiny asteroid grains can preserve chemical clues about the ingredients that may have helped [...]
