What Aliens Would Look Like, And How They Would Contact Us

For centuries, humans have dreamt up what alien life might be like. At first, it was quite unrealistic, such as huge mecha-robots that destroy civilization. But with advancing technology, the missing extra-terrestrial puzzle pieces are fitting together.

Mercury

Life forms living on Mercury, the closest planet to the sun, would have to be very tough since temperatures could range from 200 degrees in the day to -200 in the night. Since the gravity is so weak, the creatures would have to be heavy but small, as the planet is even tinier than our moon. And the planet is dotted with craters of all sorts, so the aggressive animals might fight to gain territory. They would have lots of legs to walk across the uneven surface, and many eyes too.

Venus

Venus is the closest example of hell we have in the solar system. With trails of toxic gases, lead-melting temperatures and poisonous rock, it would be a pretty tough environment to live in. That’s why the life forms would have to be super resilient, with an air filtration system and some sort of cooling mechanism.

Mars

We already know life could thrive on Mars, but really it’s a matter of where and when. The red planet had an oxygen atmosphere once, so we figure the aliens would be very human-like.

Jupiter, Saturn And Uranus

The three planets above are made of no solid materials at all. Life would have to be endlessly flying and must be light to get force from the tiniest bit of air. They must have large eyes to see through thick chemicals, and must be very light.

Neptune

Neptune’s chilly wind speeds can reach 1000mph, so Neptunian aliens must move slow and wind pushes them. The planet has lots of storms, such as an equivalent to Jupiter’s big red spot, so they would have to be tough.

I’m afraid that’s our quest across the solar system finished. We’ve found out how temperatures can effect resilience, and how winds can push sloths around the world and back. But just an extra fact: humans are mainly carbon-based, as it has lots of bonds where other atoms can join up, but extra-terrestrials might be made out of silicon, as it has almost the same structure as carbon.
