Using equipment aboard NASA’s Cassini spacecraft, scientists have discovered propylene, an ingredient in household plastic, in the lower atmosphere of Titan, Saturn’s largest moon.

Since the first test in 1980, scientists have been trying to identify the different components of Titan’s atmosphere. Tests identified propane and propyne, but it wasn’t until now that propylene was identifiable in the test results.

Propylene, explains, is used to make things like food-storage containers and car bumpers.
