No
reflecting telescopes have concave lenses and refraccting telescopes have convex lenses.
Light is found by reflecting telescopes and refracting telescopes are used to dected sound
Obsession Telescopes was created in 1989.
Deserts usually have little cloud cover and humidity, both of which interfere with visibility. Most telescopes are located far from cities so there is little light pollution.
Researchers use all of these: -- optical telescopes -- radio telescopes -- x-ray telescopes -- infra-red telescopes -- ultraviolet telescopes

no, reflecting telescopes.
No they are not bigger then radio telescopes at all.
Radio telescopes collect radio waves. Optical telescopes capture visible light waves.
Ground-based telescopes, and space telescopes. Or: refracting telescopes (main collector is a lens), and reflecting telescopes (main collector is a mirror). Or: Home telescopes (small ones), and professional ones (larger and more expensive).

All space telescopes are unmanned - unless you want to count the small telescopes on the Shuttle or IIS as space telescopes.
