The Gran Telescopio Canarias (GranTeCan or GTC) is a 10.4 m (410 in) reflecting telescope located at the Roque de los Muchachos Observatory on the island of La Palma, in the Canary Islands, Spain. It is the world's largest single-aperture optical telescope. [1] Construction of the telescope took seven years and cost €130 million.
The observatory began operation around 1984 with the Isaac Newton Telescope, which was moved to La Palma from the Royal Greenwich Observatory site at Herstmonceux Castle in East Sussex, England. The move was troubled, and it is widely recognized that it would have been cheaper to build a new telescope on-site rather than to move an existing one.
The Cumbre Vieja (Spanish pronunciation: [ˈkumbɾe ˈβjexa]; meaning "Old Summit") is an active volcanic ridge on the island of La Palma in the Canary Islands, Spain. [4] The spine of Cumbre Vieja trends in an approximate north–south direction, comprising the southern half of La Palma, with both summit ridge and flanks pockmarked by dozens of craters and cones.

During the 1949 eruption, fault displacements also had westward components with movement down the volcano's flanks. [19] The last subaerial eruption in Spain, also on La Palma, was the 1971 Teneguía eruption, which asphyxiated a nearby photographer with its fumes. [20] The eruption also caused some property damage to roads, crops, and homes. [21]
Residents on Spain's La Palma island braced Wednesday for the possibility of bigger earthquakes that could compound the damage from a volcano spilling lava more than five weeks since it erupted.
More than two months after eruptions first began, the Cumbre Vieja volcano on La Palma, one of Spain's Canary Islands, continues to create new issues for residents. Since mid-September, residents ...
The William Herschel Telescope (WHT) is a 4.20-metre (165 in) optical and near-infrared reflecting telescope located at the Roque de los Muchachos Observatory on the island of La Palma in the Canary Islands, Spain. The telescope, which is named after William Herschel, the discoverer of the planet Uranus, is part of the Isaac Newton Group of ...
