The Search for Life in the Solar System: Exploring Jupiter’s Moons with JUICE

Io, a Jovian moon, is the most geologically active planetary body in the Solar System. Despite this, experts believe that life on Io is highly unlikely due to its extreme temperatures and harsh conditions. However, the moon’s high activity levels do provide a slight chance for life to exist.

Between 2015 and 2018, scientists suggested that Ceres, the largest asteroid in the Solar System, may have a large subsurface ocean of water. Although evidence is not strong, experts still believe that Ceres could potentially contain microbial life due to its salty water flowing to the surface.

Titan, another moon in our Solar System, is unique as it’s the only planetary body besides Earth to have a complete cycle of liquid on its surface. Its liquid is made up of hydrocarbons, providing an opportunity for Titan to support life.

Triton, Neptune’s moon, rotates in opposition to its host planet – a feature that sets it apart from all other moons in our Solar System. Scientists speculate that radioactive decay within Triton releases enough heat to keep its mantle composed of water in a liquid state. This raises the possibility of life existing on this moon.

NASA spacecraft discovered Enceladus, one of Saturn’s moons, might harbor an underground ocean of water beneath its icy exterior. Additionally, Enceladus releases plumes containing saltwater and organic molecules into space from beneath its ice shell. This discovery suggests there could be potential for life existing on Enceladus.

In 2023, NASA will launch JUICE (Jupiter Icy Moons Explorer) which aims at studying three moons – Ganymede, Callisto and Europa – around Jupiter for signs of life
