Stephen Hawking, a physicist, cosmologist, in his TV show 'Into the Universe with Stephen Hawking' stated some probable structures of aliens according to the place they might be living in. If they would be living on land, they should have legs, If their environment and surrounding is visible enough, they may have eyes too and to eat or intake their food or the source of energy, they should have a mouth. So by this three means we can say that the aliens might be much human-like in physical structure whose size depends on for what purpose they are on that place for example, the alien predators, if exist, would be precise and flexible and gifted with wings to fly and reach their prey.
Life is possible on the planet that is from the right distance from its central star or sun, of which our solar system consists of Earth and Mars. and in the billions of stars in the Milky Way and billions of similar galaxies, their must be millions of Earth-like planets that support life.
Europa, a moon of the enormous Jupiter has an icy crust 15 miles thick that takes it temperature up to -260 degrees. It, due to the gravitational pull of Jupiter, stretches at some points in its orbit which, according to laws of physics, would heat the planet from inside. This rises a question of the existence of some kind of creatures that live beneath the ice crust and get continuous balance in the internal temperature. But, they are not of any harm to us as they might not know about outer space by any means.
Hundreds of Earth-like planets have been found in the Milky Way that might support life but will it be intelligent, or is their species trying to find us, or are they already here?
