Saturn’s moon Enceladus could be hiding alien life in its underground oceans, according to the European Space Agency (ESA).

Although the moon appears barren, jets of ice crystals erupt from cracks near its South Pole — and fresh analysis of data from NASA’s Cassini spacecraft has revealed that these grains contain complex organic molecules.

Researchers say these molecules may be linked to the chemical reactions needed to spark life.

Crucially, Enceladus has three vital ingredients: a steady supply of liquid water, energy from hydrothermal vents, and the right mix of chemical elements.

Lead researcher Dr. Nozair Khawaja, of Freie Universität Berlin, said: "Even not finding life on Enceladus would be a huge discovery, because it raises serious questions about why life is not present in s
