Astronomers say they have detected compelling evidence of an alien world orbiting one of the closest stars in the neighbourhood.

Alien super earth planet dubbed Barnard’s Star b is thought to be 3.2 times the mass of the Earth, and one of the closest planets to the solar system ever found - located just six light years away.

Astronomer Jon Honti of the University of Southern Queensland said the findings push the boundaries of what’s possible with current technology.
