South African-born billionaire Mr Musk has tasked himself with conquering the solar system, with his first target being Mars. However, Mr Musk may have to compete with aliens when looking to occupy a planet – but the SpaceX chief does not think that is the case.
Mr Musk, who also has Tesla in his portfolio, believes were are more than likely alone in our galactic neck of the woods.
The 49-year-old was asked on Twitter where he believes the best place in the solar system would be to find life away from our planet.
Mr Musk’s response, however, indicated he is not optimistic of finding anything.
He said on his Twitter account: “Doesn’t seem to be any life in this solar system.”
However, Mr Musk did say where the prospect of aliens is most likely.
He continued: “Maybe under the ice of Europa or extremophile bacteria below the surface of Mars.”
Mr Musk is not the only prominent figure to identify Mars and Europa, one of Jupiter’s moons, as a potential habitat for aliens.
Professor Monica Grady, Professor of Planetary and Space Science at the Open University and chancellor at Liverpool Hope University, has said: “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.
“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.
“And as for so-called alien ‘signals’ received from space, there’s been nothing real or credible, I’m afraid.”
