1. Gran Telescopio Canarias (GTC)
Gran Telescopio Canarias (GTC) is the world’s largest telescope located at the Roque de los Muchachos Observatory on the island of La Palma, Spain. The GTC has a primary mirror diameter of 10.4 meters, which allows it to collect light from very dim and distant objects.
The GTC is also equipped with a variety of advanced instruments, such as a spectroscope and CCD camera, which enable astronomers to obtain highly detailed data and images of celestial bodies.
2. Keck Observatory
The Keck Observatory is located on Mauna Kea, Hawaii, and consists of two identical telescopes with a primary mirror diameter of 10 meters. The Keck Observatory is one of the largest and most sophisticated telescopes in the world, with highly sensitive and accurate instruments.
Astronomers use the Keck Observatory to study distant galaxies and stars, and obtain data about planets outside the Solar System.

3. South Pole Telescope (SPT)
The South Pole Telescope (SPT) is the largest telescope in the Southern Hemisphere, which is located at the South Pole. The SPT has a primary mirror diameter of 10 meters, and is specifically designed to observe the Cosmic Microwave Background Radiation, which is the remnants of the massive explosion that occurred at the very beginning of the universe. With SPT, astronomers can learn about the early formation of the universe and obtain information about the structure and evolution of the universe.
4. Very Large Telescope (VLT)
