The Southern African Large Telescope (SALT) is a 9.2-metre optical telescope designed mainly for spectroscopy. It consists of 91 hexagonal mirror segments each with a 1-metre inscribed diameter, resulting in a total hexagonal mirror of 11.1 by 9.8 m. [ 2 ]
The Radcliffe Telescope is a 74 in (1.9 m) optical/near-infrared reflecting telescope located at the South African Astronomical Observatory in Sutherland, Northern Cape, South Africa. [1] When construction was completed in 1948, the Radcliffe was the largest telescope in the Southern Hemisphere, and the joint-fourth largest in the world.
SALT was inaugurated in November 2005. It is the largest single optical telescope in the Southern Hemisphere, with a hexagonal mirror array 11 meters across. SALT shares similarities with the Hobby-Eberly Telescope (HET) in Texas. The Southern African Large Telescope gathers twenty-five times as much light as any other existing African ...
With the visibility provided by 'Meerkat,' it is now apparent there are at least 1,300 galaxies in that exact spot we used to believe there were only 70.

Many modern telescopes and observatories are located in space to observe astronomical objects in wavelengths of the electromagnetic spectrum that cannot penetrate the Earth's atmosphere (such as ultraviolet radiation, X-rays, and gamma rays) and are thus impossible to observe using ground-based telescopes.
