ARIEL

Atmospheric Remote sensing Infrared Exoplanet Large survey mission (ARIEL) is an ESA telescope. During its 4-year mission, ARIEL will observe 1000 planets orbiting distant stars and make the first large-scale survey of the chemistry of exoplanet atmospheres. For a selected number of exoplanets, ARIEL will also perform a deep survey of their cloud systems and study seasonal and daily atmospheric variations.
