Tiny Deformable Mirrors Could Let NASA's Roman Telescope Image Earthlike Worlds
NASA’s Nancy Grace Roman Space Telescope will test a next-generation coronagraph using two palm-sized deformable mirrors and adaptive optics to block starlight and directly image exoplanets by reflected light; success could guide future Earth-like planet missions such as Habitable Worlds Observatory and Lazuli Space Observatory, though achieving the required level of light suppression remains a major engineering hurdle.
