Because there is less atmospheric distortion at higher altitudes, and light pollution is avoided.
Large telescopes are often housed in observatories located in remote and high-altitude areas to minimize light pollution and atmospheric interference. These locations provide clearer skies and better visibility for astronomical observations.
remote airports mean the airport in some large distance remote areas like islands,undeveloped areas. most distant areas
Refracting telescopes suffer from chromatic aberration, refracting telescopes have several surfaces to shape and polish, making large glass lenses without interior defects is very difficult, and large glass lenses are more difficult to support than large mirrors.
The receptors known as a telescopes can view large parts of the sky all at once. These receptical telescopes are usually much bigger than whole houses.
That refers to researching the Universe by observing radio waves. Special telescopes - radiotelescopes - are built for this purpose; they are often quite large.
Infrared telescopes are usually built at high altitudes to minimize atmospheric interference. At lower altitudes, the Earth's atmosphere absorbs and scatters infrared light, making it difficult to observe astronomical objects accurately. By placing telescopes at high altitudes, such as on mountain peaks, scientists can minimize the interference and obtain clearer observations of infrared radiation from space.

Keck telescopes do not exist, Keck telescope refers to the WM Keck Observatory on Mt. Kea.The Keck Observatory is comprised of several opticalreflecting telescopes, whereas aradio telescope consists of a large parabolic solid metal or screen reflector with a radioreceiver at its focus, built to detect and measure radio waves.
Two large objective lenses.
They are refracting telescopes(:Large refracting telescopes are no longer built because there were too many problems with them. There was color distortion, light pollution, and when the object hits the focal point it turns upside down. Then you don't see the object for what it really is, you see it upside down and weird-ed out. They are to complicated and scientists believed they should just stick with the simple, small, original refracting telescopes!!!!-Meghan Betts (8th grader)
Large telescopes have improved resolution over small telescopes and as such can gather clearer images of objects further away.
Telescopes are not dangerous in normal operation. A large telescope might hurt you if it fell on you.
