Starshade
A concept for blocking a star's light not inside the instrument but far in front of the telescope — a large, precisely-shaped screen flown tens of thousands of kilometres away, casting a deep shadow so an orbiting planet stands clear. A proposed external alternative to the coronagraph for future exoplanet-imaging missions.
