Nancy Grace Roman Space Telescope

The Nancy Grace Roman Space Telescope is a NASA infrared space telescope based on an existing 2.4 m (7.9 ft) wide field of view primary mirror and carrying two scientific instruments. The Wide-Field Instrument (WFI) is a 300.8-megapixel multi-band visible and near-infrared camera, providing a sharpness of images comparable to that achieved by the Hubble Space Telescope over a 0.28 square degree field of view, 100 times larger than imaging cameras on the Hubble. The Coronagraph Instrument (CGI) is a high-contrast, small field of view camera and spectrometer covering visible and near-infrared wavelengths using novel starlight-suppression technology.
