WebThe Lyot Project Coronagraph is powerful enough to see objects a million times fainter than a star and extremely close to the star. From Space To search for Earthlike planets, astronomers hope to launch an interferometer and a coronagraph into orbit where the images won't be distorted by Earth's atmosphere. Coronagraph instruments are extreme examples of stray light rejection and precise photometry because the total brightness from the solar corona is less than one-millionth the brightness of the Sun. The apparent surface brightness is even fainter because, in addition to delivering less total light, the corona has a much greater apparent size than the Sun itself.
