Earth 2.0: Scientists find 'second Earth' that could harbour life and is close enough to send space missions to

A rocky planet that might have aliens on it has been found, close enough that we could travel there. The new world is just slightly bigger than Earth and sits about four light years away, orbiting Proxima Centauri. That star is the nearest one to our solar system. As such, it is the most easily studied and understood of any "second Earth" that has ever been found. And it appears to be almost perfectly set up to serve as a home for alien life.
