Roque de los Muchachos Observatory
Acknowledged as one of the best locations for optical and infrared astronomy in the Northern Hemisphere, the Roque de los Muchachos Observatory houses the Gran Telescopio Canarias, which currently boasts the title of the world’s largest single-aperture optical telescope.
South Pole Telescope
This 10 meter in diameter telescope known as the SPT is situated at Amundsen-Scott South Pole Station. It began astronomical observations in March 2007 and conducts research that hopes to provide data on clusters of galaxies, dark energy and cosmic microwave background radiation, which in layman’s terms is the Big Bang’s afterglow. The Antarctic site was chosen because of its almost two mile elevation and the lack of atmospheric moisture which obscures and warps the light passing through it.
