Exoplanet detection is a very precise measurement. The two main methods we have (doppler shift of host star from the planet's orbit and the transit of the planet across the star) are not exhaustive by any means and biased towards discovering large planets that have short orbital periods. The fact that more Earth sized planets are being discovered and could serve as targets of analysis by JWST is an exciting prospect and I can't wait to see its development!
