An infamous "space peanut" is fittingly salty: Tiny salt crystals have been found in a peanut-shaped asteroid, implying that the largest body of space rocks in the solar system may be richer in water than astronomers thought.
The sodium chloride crystals, which only could have formed in the presence of water, were discovered in the sample of asteroid Itokawa that was returned to Earth by Japan's Hayabusa mission back in 2010.
