Scientists digging through data collected by the Cassini spacecraft have found new complex organic molecules spewing from Saturn's moon Enceladus. This is a clear sign that complex chemical reactions are taking place within its underground ocean.

Cassini data show Enceladus ejects ice from its ocean containing intermediates of biologically relevant organics, first found in an ocean beyond Earth.

Scientists believe life may exist in Enceladus' subsurface ocean. Now, a new ESA mission will send spacecraft to the moon to probe for life.

In the 17th century, astronomers Christiaan Huygens and Giovanni Cassini trained their telescopes on Saturn and uncovered a startling truth: the planet's luminous bands were not solid appendages, but vast,
