Telescope for Habitable Exoplanets and Interstellar/Intergalactic Astronomy explained

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:^[1]

• eXoPlanet Characterizer (XPC)
• Star Formation Camera (SFC),
• Ultraviolet Spectrograph (UVS)
• A separate occulter spacecraft
