The Isaac Newton Group Telescopes, located on La Palma, include the 4.2m WHT (William Herschel Telescope), the 2.5m INT (Isaac Newton Telescope) and 1m JKT (Jacobus Kapteyn Telescope). Originally general purose, they are now dedicated survey facilities. The INT hosts HARPS3, a high stability spectrograph dedicated to discovery of exo-Earth-like planets.
