[1] Most of the exoplanets currently known were discovered using indirect techniques — such as radial velocity variations of the host star, or the dip in brightness of the star caused by a transiting exoplanet.
To find an exoplanet's atmosphere, a telescope would record the spectral signature when the planet transits in front of its host star and again when it's behind.
