The image below depicts a notional telescope and coronagraph imaging an exoplanet. The telescope collects the light from the distant star and exoplanet. The light is then directed to a coronagraph that collimates the beam, making the light rays parallel, and then the beam is reflected off the apodizer mirror, which is used to precisely control the diffraction of...
A technology demo on the Nancy Grace Roman Space Telescope will help increase the variety of distant planets scientists can directly image. The Roman Coronagraph Instrument on NASA’s Nancy Grace Roman Space Telescope will help pave the way in the search for habitable worlds outside our solar system by testing new tools that block starlight, revealing planets hidden...
