Over the past 25 years Professor Angel has been in the forefront of a technological renaissance in telescopes and large optics. The Mirror Lab has made the optics for several telescopes, including the two largest mirrors ever (8.4 m diameter) for the Large Binocular Telescope on Mt. Graham, Arizona and is now making 8.4 m mirrors for the Giant Magellan Telescope and the Large Synoptic Survey Telescope. Angel has also developed concepts for imaging and searching for primitive life on Earth-like planets orbiting nearby stars. He has explored ways to cool the Earth with a space sunshade, and is now working on concentrating photovoltaic systems for solar energy.Show Less
