Earth and Saturn now have something in common: plastic. NASA's Cassini spacecraft detected the molecule propylene on Saturn's moon Titan, and propylene is one of the basic ingredients of modern plastic here on Earth.

"Propylene was actually something scientists expected to find since its chemical kissing cousins were already known to be present," writes Michael Todd.And, sorry, entrepreneurs, Wired shoots a hole in your ambitious plan to zip over to Saturn to harvest the stuff. Not only would that probably violate international treaties set up to protect other worlds, but "fossil fuels are also likely to remain relatively cheap, plentiful, and easy enough to access for many years that space-based extraction of them will remain laughable," writes Adam Mann.
