What is a Telescope? According to Google, It is an optical instrument designed to make distant objects appear nearer. It contains an arrangement of lenses, or of curved mirrors and lenses, by which rays of light are collected and focused and the resulting image magnified. There are several huge telescopes around the world. Some of them are
The Gran Telescopio Canaries
It is said to be the biggest telescope in the world so far. It is measured to be around 34 feet across. It is located in the Canary Islands of Spain. This telescope was made over a period of more ten years and had significant contributions from The University of Florida, the Universidad Nacional Autónoma de México, Instituto de Astrofisica de Canarías.
Keck 1 and Keck 2
Keck 1 Nand Keck 2 are located in Mauna Kea Observatory in Hawaii, US. There telescopes were inaugurated in 1993 and 2996 respectively and are both 394 inches or 32.8ft wide. They were named after Howard B. Keck who donated $70 million required for construction. The Keck 1 construction began in 1985 and since then, the popularity grew which attracted more donations band led to the construction of Kec 2 as well.
South African Large Telescope
The next telescope in the list is the SALT. SALT stands for South African Large Telescope. It is located in the Northern Cape of South Africa at the South African Astronomical Observatory. It is the largest satellite in the southern hemisphere and measure 30.16 feet. The SALT can capture signals that it’s northern hemisphere cannot.
Large Binocular Telescope
The LBT is 330 inch big. It was located in the Mount Graham Observatory in Arizona, US. However, it was subject of heated controversies when a tribe from a nearby forest contested its use in Mount Graham. The tribe considered the mountain to be sacred and environmentalists also expressed concerns about the work there destroying the natural habitat. Hence, the US Congress passed an act permitting it’s destruction.
These are many of largest satellites in the world and these are hugely helpful in the observation of the sky and stars.
