Instrumentation

Coronagraph

An instrument that blocks the overwhelming light of a star so the far fainter objects beside it — a planet, a disc, the solar corona — can be seen. First built by Bernard Lyot to study the Sun, it is now central to directly imaging exoplanets; SPHERE on the VLT is a modern example.
