Three useful target classes are:

* temperate rocky Earth-size planets around late M dwarfs, such as TRAPPIST-1 e;
* temperate high-gravity super-Earths around small stars, such as LHS 1140 b;
* temperate hydrogen-rich sub-Neptunes, sometimes discussed as ocean-world or Hycean candidates, such as K2-18 b.

These examples are observing targets rather than assertions that any is inhabited. An Earth twin crossing a Sun twin has atmospheric transmission features near one part per million, a one-year orbital period, and only one transit per year. Stellar photon noise, instrumental stability, clouds, and the much brighter stellar spectrum make molecular detection exceptionally difficult for JWST.
