About the mission

The Large Binocular Telescope Interferometer, or LBTI, is a ground-based instrument connecting two 8-meter class telescopes on Mount Graham in Arizona to form the largest single-mount telescope in the world. The interferometer is designed to detect and study stars and planets outside our solar system.

Unlike other interferometers, it also provides high-resolution images of faint objects over a wide field-of-view, including galaxies in the Hubble Deep Field with 10 times the Hubble resolution.
