Super-Earth

Water vapour has been discovered in the atmosphere of another world by researchers at University College London. The ‘super-Earth’, named K2-18b, is 110 light years away – making it the only known planet outside of our solar system with conditions that could support life.
It’s the only exoplanet known so far to have both water and temperatures needed for life.
One of them sits right within the habitable zone where life could exist.
They could be the location of humanity's first interstellar colony.
