One of the biggest mysteries of the universe is whether or not we're totally alone. And, although little green men in the sky do seem a little far-fetched, if you accept the concept of infinity, you have to believe that there's a possibility of life outside of what we know on Earth - although that's likely to be far, far away.
But new evidence suggests things may be a little closer to home than we thought...
For some of us, there's one big question that surrounds all aspects of life.Whether or not aliens exist seems to plague the minds of certain members of society, and it's really the not knowing that keeps them so intrigued.
The idea of believing is undeniably attractive.For many, the feeling that we aren't totally alone in the big universe can be rather a comforting point of view.
However, believing in aliens has something of a negative reputation.Many who do believe in extraterrestrial beings tend to be painted as quacks and conspiracy theorists - which is actually kind of unfair.
But the question continues to plague some of us.The worst part? It almost seems as though we'll never end up getting a straight answer to the question.
For believers, there's one area that particularly attracts attention.The US Air facility, colloquially termed Area 51, is a disused facility that was likely once used for testing experimental air vehicles. The intense level of secrecy surrounding the area has led many to believe that there's something sketchy about it, however.
But some believe that the area isn't what it claims to be.The intense level of secrecy surrounding the area has led many to believe that it's in some way related to alien life and unidentified flying objects.
For conspiracy theorists, it's something of a holy land.Many others believe that it is an area of government secrets, but, likely, of a more boring and administrative variety.
It's not just Area 51...
via: GettyThere's an endless list of places people claim to have spotted an alien or two, but when an expert thinks there could be a possibility of life on other planets, it's time to listen.
Last year, one expert claimedJupiter's moon might also hold some alien secrets.
via: GettyAlien life might actually exist in our solar system, at least that's what one expert believes.
This is what she believes...
via: GettyApparently, Jupiter's moon is hiding octopus-like creatures beneath its icy surface.
Jupiter's moon, Europa, is surrounded by speculation.
via: GettyThe moon's surface is covered with icy cold water, as well as producing an oxygen-filled atmosphere.
It's understandable why NASA has classified this mission as a high priority.
via: GettyA professor of Planetary and Space Science at Liverpool Hope University, Monica Grady, backs up this theory suggesting the seas beneath the surface could contain marine wildlife similar to the octopuses we get on earth.
She also believes there could be life on Mars...
via: GettyAlthough not the green, wide-eyed martians we're thinking. She believes there could be life beneath the surface, where it's protected from radiation.
Grady gave her opinion on the matter...
via: Getty"When it comes to the prospects of life beyond Earth, it’s almost a racing certainty that there’s life beneath the ice on Europa. Elsewhere, if there’s going to be life on Mars, it’s going to be under the surface of the planet. There you’re protected from solar radiation. And that means there’s the possibility of ice remaining in the pores of the rocks, which could act as a source of water."
She went on to say...
via: Getty"If there is something on Mars, it’s likely to be very small-bacteria. But I think we’ve got a better chance of having slightly higher forms of life on Europa, perhaps similar to the intelligence of an octopus."
Last June something incredible was spotted.
via: GettyNASA's Hubble Space Telescope found sodium chloride - which is salt to you and me - on Europa's surface.
Below the moon's frozen surface lies something fascinating.
via: GettyThe icy seawater has the ideal set up for life to thrive.
Grady explains her thoughts on life beyond the Milky Way...
via: Getty"Our solar system is not a particularly special planetary system, as far as we know, and we still haven’t explored all the stars in the galaxy. But I think it’s highly likely there will be life elsewhere – and I think it’s highly likely they’ll be made of the same elements. Humans evolved from little furry mammals that got the opportunity to evolve because the dinosaurs were killed by an asteroid impact." "That is probably not going to happen on every planet – but it’s at least possible based purely on a statistical argument. Whether we will ever be able to contact extraterrestrial life is anyone’s guess, purely because the distances are just too huge."
Grady added that we could in fact be all alone out here.
via: Getty"There’s always the chance that, within our solar system, we could be the only forms of intelligent life. If there’s only us, then we have a duty to protect the planet."
And now, another planet's name has come into the mix.
via: GettyPossible life has been discovered on Venus today!
