Hydrogen-rich atmospheres may be the key to having liquid water on the surface of a rocky exoplanet, even if the body is located up to 15 astronomical units from its parent star. A new study proposes that greenhouse effects can easily warm such a planet up to the point where it becomes habitable.
Having liquid wate... |
