About HWO SIG
The Search for Earth-Like Planets in Habitable Zones
HWO is a large infrared/optical/ultraviolet space telescope recommended by the National Academies’ Pathways to Discovery in Astronomy and Astrophysics for the 2020s.
HWO will be the first telescope designed specifically to search for signs of life on planets orbiting other stars. With a powerful set of instruments, it will also provide a platform for transformational astrophysics.
Habitable Worlds Observatory about The Search for Earth-Like Planets in Habitable Zones
"Inspired by the vision of searching for signatures of life on planets outside of our solar system, and by the transformative capability such a telescope would have for a wide range of astrophysics, the priority recommendation in the frontier category for space is a large (~6 m diameter) IR/O/UV telescope with high-contrast (10-10) imaging and spectroscopy. This is an ambitious mission, of a scale comparable to the HST and JWST space telescopes. It is also one that will be revolutionary, and that worldwide only NASA is positioned to lead."

Ultraviolet Astrophysics
Ultraviolet wavelengths are important to answer many questions in astrophysics. In addition to being sensitive to optical and near-infrared, Habitable Worlds Observatory will be sensitive to ultraviolet light.
