ExoLife Finder Telescope

The ExoLife Finder, or ELF for short, will be the world’s first telescope to create surface maps of the nearby exoplanets, including Proxima b.

ELF is a “Colossus-lite” formed from a circular array of sixteen 5 meter mirrors. ELF uses the thin “printed-mirror” technology the Colossus telescope depends on, and image-domain phasing of each off-axis parabolic segment to create a single diffraction-limited image. ELF has a total diameter of about 40m and is large enough to begin a dedicated program of Rotational ExoPlanet Imaging.
