A planet has been discovered which could be capable of supporting life.
K2-18b is located 111 light years away from Earth and orbits within its star's habitable zone, meaning it could hold water in liquid form on its surface.
It has been described as a scaled-up version of our planet, as it is significantly larger than Earth.
Researchers from the University of Texas and the University of Montreal found that the planet is probably mostly rocky with a gaseous atmosphere - a similar composition to Earth. However there is also a possibility that K2-18b is made up mostly of water with a thick layer of ice.
The planet has a twin (confusingly also called K2-18b) which is closer to its star, the red dwarf K2-18, meaning it is probably too hot to support life.
Its atmosphere will be probed further by NASA's new James Webb Space telescope after it launches in 2019.
