Why do astronomers a find it difficult to locate extrasolar planets with telescopes?
Planets are small and dark. Stars are large and bright. It is very hard to see small dark objects near large bright objects. Such planets are usually detected indirectly (e.g. if they occult the star, by the tiny wobble of the star's position in the sky, by detection of periodic doppler shifts in the star's spectrum).
