Coronagraph

A coronagraph is a specialized scientific instrument used in telescopes to block out the bright light of a star (like the Sun) so that nearby objects, such as planets or faint structures, can be observed more clearly. It works by using a mask or optical techniques to reduce the star’s glare, revealing dimmer features that would otherwise be hidden. This allows astronomers to study the star’s surroundings, including potential planets, solar phenomena, or other celestial structures, providing valuable insights into the composition and behavior of stars and their environments.
