Kepler-22b: The Ocean Exoplanet Most Likely To Support Life


Kepler-22b could be an ocean planet and sits perfectly in the habitable zone that some astronomers call the “Goldilocks region.” This is where the surface temperature is neither too hot nor too cold, allowing liquid water to exist on the surface.

As we all know, water is essential if life is to flourish, meaning that this distant world could host extraterrestrial life. However, just because the planet is within the habitable zone doesn’t automatically mean that it’s going to have water.

Some astronomers speculate that Kepler-22b could in fact be a smaller gas giant. At over 600 light-years away, it is going to be difficult to be sure whether the planet is Earth’s twin or not, but as Natalie Batalha, Kepler deputy science chief, said, “It’s not beyond the realm of possibility that life could exist in such an ocean.”
