Is There Alien Life in the Solar System? – The Science Quiz

The Jovian moon known as Io is the most geologically active planetary body in the Solar System. While its constant activity makes it unlikely for life to exist on this moon, there is a possibility that the warmth generated by its geological processes could potentially support life.

In recent years, data collected between 2015 and 2018 suggested that the largest asteroid in the Solar System, Ceres, may have a large subsurface ocean of water. Though the evidence is still weak, scientists believe that very salty water could flow to the surface of Ceres, potentially containing microbial life.

Titan, a moon of Saturn, is unique in that it is the only planetary body other than Earth to have a complete cycle of liquid on its surface. However, unlike water on Earth, Titan’s liquid is made of hydrocarbons, raising the possibility of hosting life on this moon.

Triton, a moon of Neptune, rotates in the opposite direction to its host planet and has an unusual heat source: radioactive decay within its mantle keeps its water-made mantle in a liquid state. This provides conditions for life to exist on Triton.

Enceladus, another moon of Saturn, has been discovered to contain an underground water ocean and eject plumes of saltwater and organic molecules into space. This hints at the possibility of life existing on this icy moon.

NASA’s Jupiter Icy Moons Explorer (JUCE) spacecraft will be launched in 2023 with a mission to study Ganymede, Callisto, and Europa for signs of life when it reaches Jupiter in 2031. This mission aims to further uncover more about these moons’ potential for supporting life.
