In all our exotic theories on the origins of UFO occupants, do we neglect the possibility that they come from within our Solar System? There is ongoing, exciting news from NASA about the alien moons of our Solar System - notably, Jupiter and Saturn’s many natural satellites.
Jupiter was thought to have sixteen moons until several dozen more moons were discovered by astronomers with much-improved telescopes. The largest of the Jovian moons are Io, Europa, Ganymede and Callisto.
Saturn has 62 moons, many of them are newly discovered. Mimas, Enceladus, Tethys, Dione, Rhea, and Titan are six of the most intriguing.
Are the scientists wrong to dismiss the possibility of higher life-forms in the huge H2O ocean of Saturn’s 6th largest moon, Enceladus, for instance? We know that the dolphins, porpoises, whales, and other sea mammals of Earth possess a higher form of intelligence – an intelligence which we have yet to fully understand. There is some evidence that aliens may communicate with our sea mammals.
If there are multi-celled life forms in sea life on Enceladus, possibly similar to the illustration above, who is to say that those higher forms did not evolve into a space-going race as the eons progressed?
It is difficult to perceive how an Enceladusian microbe might have evolved into a highly intelligent alien who cruises around our skies in a UFO; however, it is still possible in the unimaginable splendor of the universe – just look at the roots of Homo sapiens.
Discovering complex life-forms within our Solar System is a realistic possibility because in the not-distant future, we will be able to explore these worlds; we just might set down on Enceladus in the next 25 years!
Let’s look at the four most likely worlds in the Solar System which might support higher life-forms:
The sixth-largest moon of Saturn has been called the most promising bet for life thanks to its moderate temperature and the presence of water and simple organic molecules. The surface of the icy moon is thought to be about 99 percent water ice, with a good chance of liquid water beneath.
Observations from the Cassini probe’s 2005 flyby of Enceladus suggest the presence of carbon, hydrogen, nitrogen and oxygen — organic molecules thought to be necessary to develop life.

Jupiter’s moon Europa also seems a possible stomping ground for aliens due to its potential water and volcanic activity. Though the surface is frozen, it has recently been confirmed that buried underneath is an ocean of liquid water 2 to 3 times greater than Earth’s water!
Volcanic activity on Europa provides life-supporting heat, as well as important chemicals needed by living organisms. Europa has water volcanoes spewing far into space. Microbial life could potentially survive near hydrothermal vents on Europa, as it does on Earth.(Image: Galileo Project, JPL, NASA; reprocessed by Ted Stryk)
Saturn’s largest moon looks suspiciously like it might host or have hosted life, because its thick atmosphere is rich in compounds that often mark the presence of living organisms.
For instance, Titan’s air is filled with methane, which is usually destroyed by sunlight. On Earth, life constantly replenishes methane, so it might similarly be responsible for the methane on Titan.
Titan is rather cold, however, and if liquid water exists, it must be deep beneath the frozen surface. (Image: NASA)
Jupiter’s moon Io is one of the few solar system moons to support an atmosphere, and it contains complex chemicals promising for life. Volcanism on the moon also makes it warmer than many others — another good sign. Io is still a long shot, though, because its location inside Jupiter’s magnetic field means it is constantly being pelted with lethal radiation. Its violent surface also seems inhospitable, with temperatures often too cold to support life, as well as molten hot spots that are equally deadly.(Image: The Galileo Project, JPL, NASA)
We have seen on Earth that some life can adjust to relatively large doses of constant radiation as well as the advanced life-forms which thrive in the extreme depths and blackness of our oceans. These are not just microbes but octopus, crabs, and other complex life-forms.
But, how can we get to the moons of Jupiter and Saturn in a reasonable amount of time to discover and perhaps meet the aliens who live there? How can human beings ever travel fast enough?
There is a fascinating new theory on how to achieve space travel:
Gravitational corridors could help spacecraft fly across the solar system like ships on ocean currents. Scientists are trying to map the twisting 'tubes' so they can be used to cut the cost of space travel. Each one acts like a gravitational Gulf Stream, created from the complex interplay of attractive forces between planets and moons.
