EXOPLANETS
How does a planet’s colour influence its habitability?
Much like a white shirt keeping you cool on a bright summer day, a planet’s colour plays an important role in keeping a planet’s temperature just right for life. Our search for life is currently focused on finding exoplanets with temperatures in a range that allow for liquid surface water. An exoplanet with a dark surface like ocean or basalt will absorb a lot of the incoming stellar energy and heat up. A brighter surface like snow or sand will reflect stellar energy and prevent the temperature from rising.
