Polycyclic aromatic hydrocarbons (PAHs) are organic pollutants found in car exhaust and cigarette smoke. They are also found in supernova remnant N132D, the material left over after an old star exploded. Scientists theorize that PAHs play an essential role in the development of life.

What is probably most unusual about the moon is its shape. Iapetus is not shaped like most large moons. Instead, it has a unique bulging ridge around its equator that makes it shaped like a walnut, prompting people to nickname it the “Walnut Moon”.
