News of water on Saturn’s moon, Enceladus, makes it the fifth moon in our solar system with the possibility of housing alien life. Thanks to this exciting new addition, Sci-Fi fans can rejoice as the hope of finding extraterrestrials is yet again ignited.
However, in case you aren’t an astronomy buff or you have simply forgotten about the other four moons that have water in the wake of this thrilling discovery, they are:
- Earth’s moon
Water on Earth’s Moon
For a time, it was dismally accepted that Earth’s moon was bone-dry. Then, in October of 2009, NASA’s LCROSS Mission brought back proof of water ice on its surface. This discovery gave way to the belief that there is more water below the surface, but this is still being investigated.
While it would be great to find that we have alien neighbors sipping glasses of water on the moon orbiting our planet, chances of this would be more likely on one of the other moons on the list.
Water on the Galilean Moons
Jupiter, the fifth planet from the Sun, has four large moons known as the Galilean Satellites. Of these moons, three have been found with water.
The largest of these moons is Ganymede. As it is also the largest moon in the entire solar system, it would be outstanding to know that water on this moon is sustaining an alien species, because there is plenty of room to, say, move in next door to learn their ways. Until then, though, all we know is that right under its surface is a thick layer of frozen ice.
Callisto, the Galilean Moon that orbits farthest from Jupiter, has an interior similar to Ganymede, except the ice layer much deeper. Still, despite the ice being closer to the core than the surface, it has better luck of sustaining life than the Earth’s moon at this point.
Then there is Europa, whose surface is mostly solid ice. If any moon was most likely to be the home of a strange alien species, it would be this one, as it is believed to have an entire ocean of liquid water right beneath its icy surface. Though this belief has yet to be confirmed, if it does turn out to be true, it will have twice as much water than Earth does, which is more than enough fuel for the imaginations of Sci-Fi geeks everywhere.
While the discovery of other intellectual beings in the universe may not be as close as some of us wish, it is still great to learn more about the other planets and moons out there. So welcome, Enceladus, to the list of moons with water!
