If we didn't have them we could not see as far and we would be quite far behind on our discoveries in astronomy.

∙ 10y agobecause when you look through a telescope a planet or star suddenly appears much bigger and brighter, and also you can see a whole lot more stars that you didn't know were there.

How astronomy is related to technology?
All of the observational tools needed by astronomers: astrolabes, quadrant, clocks, sextants, octant, spectrographs, polarimeters, telescopes, optical mount, radio telescopes, space telescopes, etc. are products of various technologies.
Is the design of radio telescopes very similar to the design of refracting telescopes?
no, reflecting telescopes.
Is refracting telescopes bigger then reflecting telescopes?
No
How are reflecting and refracting telescopes different?
reflecting telescopes have concave lenses and refraccting telescopes have convex lenses.
What are reflecting and refracting telescopes designed for?
Light is found by reflecting telescopes and refracting telescopes are used to dected sound

What other kinds of radiation are detected by telescopes?
Researchers use all of these: -- optical telescopes -- radio telescopes -- x-ray telescopes -- infra-red telescopes -- ultraviolet telescopes
Most telescopes are telescopes?
refracting
Is the design of radio telescopes very similar to the design of refracting telescopes?
no, reflecting telescopes.
Are optical telescopes much bigger then radio telescopes?
No they are not bigger then radio telescopes at all.
How radio telescopes differ from optical telescopes.?
Radio telescopes collect radio waves. Optical telescopes capture visible light waves.
What are the major types of optical telescopes?
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).
Is refracting telescopes bigger then reflecting telescopes?
No
Where are telescopes generally found?
At a store for telescopes!
Are space telescopes manned or unmanned satellites?
All space telescopes are unmanned - unless you want to count the small telescopes on the Shuttle or IIS as space telescopes.
How are reflecting and refracting telescopes different?
reflecting telescopes have concave lenses and refraccting telescopes have convex lenses.
What are the instruments used to study the solar system?
Telescopes in general. Optical telescopes Radio telescopes Gravity wave telescopes
