How this affects you

An unknown chemical signature has been observed on the surfaces of Titan and Pluto, which could indicate the presence of new or uncharacterized compounds relevant to the moons' compositions and astrobiological potential. This finding suggests that our understanding of these distant bodies' chemistry is incomplete.
