Your guide to exoplanet habitability 

(for life as we know it) 



ATMOSPHERE


Temperate Climate

To keep oceans of liquid water, a planet requires a temperate climate. 


This means an atmosphere that supplies the right amount of global warming.


Water, carbon dioxide, methane, clouds and particles all can impact surface temperature.


Detecting gases that are made by life is one way we could confirm a planet’s habitability.
