The reason why astronomers send things in space and not set them on a mountain, is because distortion becomes minimum. anything that goes in space will capture a better signal and picture of everything.
Satellites
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.
All space telescopes are unmanned - unless you want to count the small telescopes on the Shuttle or IIS as space telescopes.
Telescopes are placed in space to view distant galaxies primarily to avoid atmospheric distortion and light pollution, which can obscure and affect the quality of observations taken from Earth. Space telescopes also provide a clearer and more stable view of the universe, allowing for more accurate and detailed observations of distant galaxies.
Mainly visual and radio. But there are Xray, UV and IR.
no
hubble space station
Some frequencies of light are attenuated by water vapor.
It is a space based XRAY telescope
they use space probes,satellites,and of coarse,telescopes.
Radio signals are sent from Earth, to operate the telescopes.
light telescopes and radio telescopes whether installed on earth or on space vehicles
