10 Places Most Likely To Harbour Alien Life

One of the most recently discovered entries on our list, Kepler-452b caused quite the stir in July of 2015 when it was excitedly dubbed "Earth 2.0".

The exoplanet, orbiting the star known as Kepler-452, is 60% larger than the Earth and scientists think that it is likely to have a rocky surface similar to Earth. It orbits the sun-like star in the much-sought-after Goldilocks zone, it's year is about the same length as a year on Earth, surface temperatures and conditions are likely to be similar and it is, for all intents and purposes, just like Earth's bigger, slightly older cousin.

The reason why scientists have been getting so excited about Kepler-452b is that it has spent roughly six million years in that Goldilocks Zone sweet spot, more than enough time for life, perhaps even intelligent life, to have evolved on its surface.

Even if we find that, for whatever reason, complex life hasn't managed to take hold on Kepler-452b, some scientists think it might still make quite a cosy home for space-faring humans in the distant future. That's if we can manage to cross the 1,400 light-years of open space between us and the planet's surface.

Reckon we've missed one? Let us know in the comments.
