The world's largest telescope in the current view cannot lump together, butshould be based on various properties to identify the largest telescope, the following is the world's ten largest largest astronomical telescope, hope that we can understand the world's largest telescope!
1, add the columns of large telescope (Gran Telescopio Canarias) at present, the world's largest ground based telescope is to add the column of large telescope, it is a small island located in the Spanish Paermajia that column in the islands,allegedly, plus the string of islands placed a number of large telescope. Thetelescope mirror diameter of 10.4 meters, is composed of a specular hexagonal assembly 36 customized, installation requires accurate to 1 mm range. It is a total investment of 175000000 dollars, was built by the Spanish government, tworesearch institutions in Mexico and American Florida University cooperation.Before the telescope installed components, each component is named folklorelocal islands in the God in the name, or to the island animal and plant names. In August this year, 36 mirror assembly with the big telescope last batch ofinstallation is complete, but its first appearance was in 2007 July, was onlyinstalled 12 mirror assembly. 2, the Keck telescope (Keck I & II) W. M. The Keck telescope is located in Hawaii's Mauna Kea peak, 4200 meters above sea level, the Keck I & II is two identical telescope, which are composed of 36 pieces of mirror hexagonal assembly, the whole mirror diameter of 10 meters,each mirror diameter is 1.8 meters, and the thickness of only 10 cm, through active optical support the mirror system, maintain high accuracy. The mainequipment of the telescope has three: near infrared camera, high resolution CCDdetector and a high dispersion spectrograph. Each telescope is 8 storeys high,weighing 300 tons, the current can reach nanometer level precision of astronomical observations. In 1993, the Keck I telescope into scientificobservations using the Keck II telescope, 1996 put into use. Astronomers using the telescope to 1-5 a night, must advance by the Committee for approval, andthe operation of the telescope in the committee's assistance, usually astronomersin Hawaii wa Mei ya (Waimea) astronomical observation headquarters remotedata collection. The southern 3, Africa large telescope in southern Africa largetelescope, referred to as SALT, a small peak is located in Africa south, it is the largest single optical telescope in the southern hemisphere. It is composed of 91 pieces of mirror hexagonal assembly, the whole mirror the real effective diameter of 10 meters. A telescope to detect faint light from the moon like a candle, thetelescope in 2005 for the first time use. From South Africa, the United States,Germany, Poland, Britain and New Zealand National astronomers were used thesouthern African large telescope. 4, the hobby Eberly telescope the hobby Eberly telescope located in Fuwakesi mountains of the state of Texas, referred to as HET, it is very similar to the southern African large telescope. It is composed of91 pieces of mirror hexagonal assembly, each mirror is 1 meters in diameter, by the small computer control motor to persistent ranking. The whole mirror diametercan reach 11 meters, the actual availability of only 9.2 meters. The telescope will be able to detect than the human eye can be observed in dark light 100000000 times of cosmic rays. The designed and constructed using a unique way, so that it can absorb large light, especially the spectrometer, the cost is very low.
5, the Large Binocular Telescope large binoculars or LBT, it consists of twoclosely adjacent 8.4 diameter telescope, can be separated from the work, when combined with work as a single, larger telescope. The first telescope is in the United States in 2004 Arizona Graham Hill erection, second telescopes from 2005 to start the installation, until the beginning of this year, two telescopes to achievethe merge type observation. 6, the Pleiades telescope Pleiades telescope inHawaii Mo halfway up the mountain Mauna Kea, the telescope is 8.2 meters in diameter, which is an optical / visual infrared telescope, which has three characteristics: one is the mirror of thin, acquire high imaging quality by active optics and adaptive optics; the two is realization of high precision tracking; three is the use of a cylindrical observation room, automatic control of ventilation andair filters, the exclusion of thermal turbulence to achieve the best condition. Thetelescope adopts dense row type (Serrurier) truss, the main frame and the auxiliary frame keep parallel on the move. It can and the Keck Observatory shareother telescope observation data. It has the world's largest single lens telescope,the right to use the National Astronomical Observatory of Japan, but can be from all over the world, astronomers use. The naming of the telescope from a youngstar clusters - "the Pleiades" (Pleiades). The first scientific observations in 1999.7, the European Southern Observatory's very large telescope interferometerwhich is composed of 4 8.2 meter diameter telescope Cerro Paranal in Chile,located in the mountains, they can operate alone, or the formation of a very large telescope interferometer. The instrument very large telescope assembly can provide detailed observations of the stars, the change of motion capture1/1000000000 seconds. This combination of astronomical observations than thehuman eye can detect visible light dark 4000000000 times of cosmic rays. Two telescopes 8, Gemini telescope Gemini telescope is not close, this is the two of 8 meters diameter optical / infrared telescope, are located in both hemispheres onthe two best astronomical observation point.'s other telescope is located in the northern hemisphere telescopes and Hawaii cooperative operation,is located in the southern hemisphere telescopes located in(责任编辑：最有料)
