Scientists have announced the discovery of a freezing Earth-mass world 13,000 light years away.
It might not be the best place to look for signs of alien life, but the new planet, which has been assigned the rather inelegant moniker OGLE-2016-BLG-1195Lb, happens to be the smallest extrasolar world ever found using the gravitational microlensing planet-hunting technique.
Situated a whopping 13,000 light years away, this distant planet is probably far too cold to support life, even though it orbits its parent star at a distance similar to that of the Earth from the Sun.
The reason for this is because its star is very small and dim - roughly 7.8 percent the mass of the Sun - meaning that it might not even be a proper star at all.
