Science Magazine probes Earth-sized exoplanets with a new telescope concept now being studied by NASA. The Habitable Exoplanet Imaging Mission, or HabEx, is a mission concept with a mirror up to 6.5 meters across — as big as the JWST’s — but would be armed with instruments sensitive to a broader wavelength range, from the ultraviolet to the near-infrared, to capture the widest range of spectral biosignatures. The telescope would be designed to reduce scattered light and have a coronagraph and starshade to allow direct imaging of Earth-sized exoplanets.
