NASA’s Kepler spacecraft has discovered a planet in a galaxy far, far away that could have water, which means that maybe — just maybe — it might support life.
The planet, named Kepler-22b, is more than twice as big as Earth and is 600 light years away. Its orbit lies in the “habitable zone,” also called the “goldilocks zone” because it’s not too hot and not too cold.
Scientists don’t know if the planet is rocky, like Earth, or made of gas, like Venus, but if its atmosphere is similar to ours, the temperature on the planet would likely be around 72 degrees.
The NASA Kepler mission is designed to discover Earth-like planets. Scientists believe a planet would only be able to support life if it has moderate temperature and if it contains liquid water.
