Tag: Observatory Roque Muchachos

The Observatory of El Roque de Los Muchachos from the island of La Palma (altitude 2,420 m) is home to one of the most extensive fleets of telescopes to be found anywhere in the world. The reasons for being in La Palma is its latitute which allows the observation of the sky in both celestial hemispheres but more importantly, due to the excellent quality of its sky. This is: the darkness of the island a stable atmosphere the low air and light pollution the observatory being above the cloud level for more than 300 days on a given year the sky of La Palma is also protected by law from 1989 (Law of the sky), enforcing the control of light pollution by regulating street lighting and air communication routes.   Visits to the Observatory can be booked here: Daytime Visits.   New telescopes at Observatory Roque Muchachos The newest incorporation to the Observatory facilities in recent years are 23 Cherenkov telescopes which will be part of the International Cherenkov Telescope Array (CTA). La Palma will be the northern site for this network. The largest Cherenkov telescopes will have 23 m in diameter. In 2016, the fundation has been laid for the 3rd Cherenkov telescope in La Palma. The Cherenkov Telescope Array (CTA) is the next generation ground-based observatory for gamma-ray astronomy at very-high energies. With more than 100 telescopes located in the northern and southern hemispheres, CTA will be the world’s largest and most sensitive high-energy gamma-ray observatory. This network will be capable of observing the whole of the sky, inside and outside our galaxy as it will have 120 telescopes between both hemispheres. It will also cover a very wide range of energies ranges from several dozen Gev to 100TeV (1 TeV = 1012 eV) seeking to understand the
