Telescopio Nazionale Galileo 30th anniversary

"At the summit of the island of La Palma, at an altitude of nearly 2,400 meters, the Roque de los Muchachos Observatory enjoys one of the darkest and clearest skies in the Northern Hemisphere. Here, the Telescopio Nazionale Galileo has been observing the universe since 1996; with its 3.58-meter mirror, it is the largest optical and infrared telescope in Italian astronomy."
