The building boasts an impressive 102 cm refracting telescope, considered one of the largest in the world at the time of its construction. Visitors can explore the observatory’s historic facilities and learn about its contributions to modern astrophysics.
5. Observatorio del Roque de los Muchachos, Canary Islands, Spain
Managed by the Institute of Astrophysics of the Canaries, this observatory is situated on the slopes of Mount Teide, an extinct volcano on the island of Tenerife. The site offers breathtaking views of the surrounding landscape and is one of the best locations for astronomical observation in the northern hemisphere.
The Roque de los Muchachos Observatory is home to some of the world’s most advanced telescopes, including a 3.5-meter diameter telescope that provides high-resolution images of the sun’s surface. Visitors can explore the site’s unique architecture and learn about its scientific contributions.
6. Arecibo Observatory, Puerto Rico
Operated through Cornell University, the Arecibo Observatory is one of the world’s most renowned astronomical research facilities. This radio telescope consists of an antenna opening of 305 meters, making it the largest single-opening telescope ever built.
Arecibo has been at the forefront of scientific discovery, including the period of rotation of Mercury, the periodicity of the Crab Nebula, and the discovery of pulsars. Visitors can explore the observatory’s facilities and learn about its groundbreaking research.
7. Anglo-Australian Observatory (AAO), Australia
Cooperative between the UK and Australia, this observatory is located about 450 km north-west of Sydney. The AAO boasts an impressive collection of telescopes, including the Anglo-Australian Telescope and the UK Schmidt Telescope.
These instruments have enabled scientists to measure the distance of thousands of galaxies and quasars, providing invaluable insights into the large-scale structure of the universe. Visitors can explore the observatory’s facilities and learn about its contributions to modern astrophysics.
8. University of Tokyo Atacama Observatory, Chile
Located in Chile’s Atacama Desert, this observatory is home to two main telescopes: the MiniTAO Telescope and the Infrared Telescope. The MiniTAO Telescope boasts a 1-meter diameter primary mirror, making it one of the highest observatories in the world.
The Infrared Telescope is currently under construction, designed to operate in infrared wavelengths. This facility will play a significant role in unraveling the mysteries of the universe, particularly in the realm of exoplanetary science.
