ATACAMA DESERT, Chile (PNN) - April 6, 2017 - Scientists say they have detected an atmosphere around an Earth-sized planet for the first time.
They have studied a world known as GJ 1132b, which is 1.4-times the size of our planet and lies 39 light years away.
Their observations suggest that the "super-Earth" is cloaked in a thick layer of gases that are either water or methane or a mixture of both.
The study is published in the Astronomical Journal.
