When we think of Aliens, it’s not uncommon for us to envisage a small-bodied, grey- skinned bug-eyed-being with an oversized forehead. But the question of when life beyond Earth will be proven is one of humanity’s most profound and unanswered questions, whichever way evolution may decide to present them.

With record-breaking technological advances having been made toward new astronomical discoveries, including that of NASA’s Kepler space telescope which captured evidence of other potentially habitable planets in the Milky Way galaxy, many scientists believe we are closer than ever to retrieving the answer to this all-important question.

Astrobiologist and planetary scientist at America’s Jet Propulsion Laboratory Dr Kevin Hand and his team are amongst those that think us having the answer to ‘are we alone?’, is certainly not lightyears away.

He revealed that recent missions to the surface of planet Europa have provided us with clues which indicate the presence of liquid water in a form which could support life. Other recent discoveries suggest our solar system teems with environments that could support life as we know it.

NASA’s chief scientist predicts that signs of alien life will be founded by 2025:

“I think we’re going to have strong indications of life beyond earth within a decade, and I think we’re going to have definitive evidence within 20 to 30 years”.

The Cassini space probe ends its missing in September 2017 and has been hotly tipped as one to keep an eye on for an answer to alien-life existence.

Doctor Simon Foster from Imperial College London thinks that the probe orbiting Saturn's moons Enceladus and Europa have a, "good prospect of finding life', he told the Express.

So, with the experts sure enough that it won't be long until we have an answer, Paddy Power are also thinking along the same lines, believing there's a 1/22 chance that alien-life will be proven either this year or next year.

Paddy Power also offer a 1/18 chance for the discovery to be made in 2019 and a 1/18 chance that alien life will be proven in 2020 or later.

Currently Paddy Power are the only ones partaking in the race to extra-terrestrial answers, but placing your bet with a world-class leading bookmaker at Gambling Deals- and with up to 20% cashback available every time you play, it’d be a bright move!

It's only a matter of time, so they say! With a breakthrough on the horizon, what will you predict?
