Telescope for Habitable Exoplanets and Interstellar/Intergalactic Astronomy
Introduction '''Telescope for Habitable Exoplanets and Interstellar/Intergalactic Astronomy''' ('''THEIA''') is a NASA-proposed 4-metre optical/ultraviolet space telescope that would succeed the Hubble Space Telescope and complement the infrared-James Webb Space Telescope. THEIA would use a 40-metre occulter to block starlight so as to directly image exoplanets.It was proposed with three main instruments and an occulter:*eXoPlanet Characterizer (XPC)*Star Formation Camera (SFC),*Ultraviolet Spectrograph (UVS)*A separate occulter spacecraft
