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. This constant activity makes it unlikely for life to exist on this moon, but not impossible, as the warmth generated by its geological processes could potentially support life.

Data collected between 2015 and 2018 suggested that the largest asteroid in the Solar System, Ceres, may have a large subsurface ocean of water. While the evidence is still weak, it is believed that very salty water could flow to the surface of Ceres, potentially containing microbial life.

Titan, a moon of Saturn, 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, is unique in that it is the only moon in the Solar System rotating in the opposite direction to its host planet. Scientists believe that the heat generated by the radioactive decay of rock in Triton’s interior keeps its mantle, made of water, in a liquid state, potentially providing conditions for life to exist.

NASA spacecraft have discovered that Enceladus, a moon of Saturn, may contain an underground water ocean. This moon also ejects plumes of salt water and organic molecules from its subsurface through the ice shell into space, hinting at the possibility of life on Enceladus.

The Jupiter Icy Moons Explorer (JUICE) spacecraft, launched by NASA in 2023, is set to reach Jupiter in 2031 to study the moons Ganymede, Callisto, and Europa for signs of life. This mission aims to uncover more about the potential for life on these icy moons of Jupiter.
