A substance found on the surfaces of Saturn's largest moon, Titan, and the distant dwarf planet Pluto could hold remarkable clues about how life itself began—both on distant worlds and potentially here on Earth.

Researchers studying these icy bodies have identified chemical signatures that suggest prebiotic chemistry—the type of molecular activity that precedes the emergence of life. This discovery expands our understanding of where life-forming processes might occur in our solar system and beyond, opening new possibilities for astrobiology. Read the full story →
