Exploring the possibility of life beyond Earth has been one of the most intriguing questions for scientists and the general public alike.

Jupiter is the largest planet in our solar system and has more than 79 moons orbiting it. Among these moons, Europa and Ganymede are two of the most promising candidates to harbour life beyond Earth.

Europa is slightly smaller than Earth's moon and is covered by a thick layer of ice, beneath which scientists believe there is a liquid ocean. This subsurface ocean is estimated to contain two to three times the volume of all the Earth's oceans combined. Recent observations made by the Hubble Space Telescope suggest that plumes of water vapour may be erupting from Europa's surface, providing evidence for the existence of this subsurface ocean.

Ganymede, on the other hand, is the largest moon in the solar system and is the only moon known to have its own magnetic field. Scientists believe that Ganymede has a rocky mantle and a subsurface ocean, similar to Europa. Additionally, Ganymede's surface contains regions of both dark and light terrain, suggesting a complex geological history.

Both Europa and Ganymede are considered prime targets in the search for extraterrestrial life because they contain the three essential ingredients for life: liquid water, organic compounds, and a source of energy. NASA's upcoming Europa Clipper mission, set to launch in the 2020s, will conduct detailed investigations of Europa's surface and subsurface to determine if the moon is habitable for life as we know it.

The discovery of life on Jupiter's moons would be a monumental achievement for science and would revolutionize our understanding of the universe and our place in it. It would also have profound implications for the search for life elsewhere in the Cosmos.
