NASA recently announced the discovery of a new, Earth-sized planet in the habitable zone of a nearby star called TOI-700. We are two of the astronomers who led the discovery of this planet, called TOI-700 e. TOI-700 e is just over 100 light years from Earth—too far away for humans to visit—but we do know that it is similar in size to the Earth, likely rocky in composition and could potentially support life.
