> Exoplanets are too far away and too small to image directly.
If you mean resolving details of the exoplanet, then yes that is currently true. But we have imaged exoplanets directly, meaning taken an image of a star where one can also see the planet directly in the image. [0] has a list of directly imaged exoplanets.
It's an impressive technique. Direct imaging finds planets that would be unlikely to be identified via other detection techniques (such as measuring the wobble in the parent star's radial velocity or measuring photometric eclipses as the planet passes between us and the parent star).
