Francisco Sánchez, the father of astronomy in the Canary Islands and Director of the Instituto de Astrofísica de Canarias in Tenerife.
The Teide Observatory on Tenerife and Roque de los Muchachos Observatory on La Palma are both operated by the Instituto de Astrofísica de Canarias (IAC) and are currently home to telescopes and other instruments belonging to 60 scientific institutions from 17 countries. Roque de los Muchachos Observatory on La Palma was inaugurated on 29 June, 1985, by the Spanish Royal Family and six European heads of state. These observational facilities, combined with the scientific and technological resources of the IAC in La Laguna (Tenerife) and Astrophysics Centre on La Palma (CALP), constitute the European Northern Observatory (ENO). La Palma now hosts the world’s largest single-aperture optical telescope—the 10.4 metre Gran Telescopio Canarias (GTC).
