Cassini Probes Finds Plastic on Titan

The NASA Cassini spacecraft has found propylene, a chemical used in the boxes that store food and other consumer products, on Titan, one of Saturn's moons (the largest). This is the first identification of plastic on a Moon or a Planet outside the Earth. The small amount of propylene has been identified in the lower atmosphere of Titan by the instrument CIRS (Composite Infrared Spectrometer), an infrared ray instrument that can measure the heat emitted by Saturn and its Moons.
