Enceladus, Saturn’s walnut-shaped moon, contains complex organic molecules within its oceans, according to research published Wednesday in Nature, further distinguishing the celestial entity as one of the most likely worlds to host alien life in the solar system.

The study, led by Frank Postberg and Nozair Khawaja of the University of Heidelberg, is based on data collected by NASA’s Cassini orbiter before it plunged into Saturn in September 2017 (RIP).
