What instrument is employed in direct imaging to overcome the primary obstacle of detecting an exoplanet?
Answer
Coronagraphs.
Coronagraphs are specialized instruments used to physically block the overwhelming glare of the central host star, enabling the fainter light of the orbiting planet to be observed.
