Why are radio telescopes often placed in valleys?
Placing the telescopes in valleys is believed by some people to slightly reduce radio interference, but when radio telescopes are placed in valleys, it is usually because they are so large and the mountains work as supports, to reduce the cost.
Large telescopes are often housed where?
On top of mountains.
Telescopes are placed in space to view distant galaxies primarily to?
aviod the absorption of the light or other radiations in the atmosphere of earth
Why are some telescopes placed in orbit around the earth?
because looking through the Earth's atmosphere can distort the incoming light.
What is absorbed by water in Earth's atmosphere and requires that telescopes forobserving at these wavelengths be placed on mountain tops or in space?
Some frequencies of light are attenuated by water vapor.

Why are big telescopes found on top of mountains?
The Earth's atmosphere provides interference to optical telescopes because the molecules in the air scatter and disrupt light. Many telescopes are placed at high elevation because the atmosphere is thinner and will cause less interference.
Why do optical astronomers place telescopes at the top of mountains while radio astronomers put their telescopes in valleys?
Optical telescopes are placed high to avoid having to look through the thickest part of the atmosphere. Radio telescopes are place in valleys to avoid the effects of man-made electrical noise in the telescope.
Large telescopes are often housed where?
On top of mountains.
Why are x-ray telescopes and gamma - ray telescopes in space?
The earth's atmosphere doesn't let these rays reach the ground, so the telescopes are placed in orbit where they can receive the rays.
Where do x ray telescopes have to be placed in order to view object in space?
Satellites
Why have astronomers built the largest visible light telescopes on the tops of mountains?

Why are radio telescopes not located on top of mountains like the visible light telescopes?
It is not necessary to do so, as atmosphere doesn't distort radio signals as much as visible light.
Why do astronomers currently prefer orbiting telescopes over earth based telescopes?
Orbiting telescopes are located in the sky, where it is not affected by the turbulence of the atmosphere, while ground-based telescopes are located on the ground, where the atmospheric turbulence (the moving of air) is greater. This is also the reason that some telescopes are built on mountains where the atmosphere is thinner and turbulence is smaller.
Where are griffins placed?
Griffins can't really be placed anywhere; in mythology they could be located in India, in the Hyperborean Mountains or the Riphean Mountains.
Astronomers often locate telescopes on mountains to?
To - minimise the distortion of the received image due to light pollution.
