The most obvious answer to me is using them to look at the Sun. You know how a magnifying glass can be used to burn paper. Well a telescope is worse.
Another one is when your leg crashes into the tripod that is holding your telescope. I have a big telescope and I did this and it hurt!
What else can I help you with?
Are telescopes dangerous?
Telescopes are not dangerous in normal operation. A large telescope might hurt you if it fell on you.
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
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).
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.
What have telescopes found out?
telescopes have found out that im AWESOME
How are refraction telescopes and reflecting telescopes similar?
they the same
How are reflecting and refracting telescopes different?
Reflecting telescopes use mirrors to collect and focus light, while refracting telescopes use lenses. Reflecting telescopes typically have a closed tube design which protects the mirrors from dust and other contaminants, while refracting telescopes are more prone to chromatic aberration. Reflecting telescopes are generally easier to manufacture at larger sizes compared to refracting telescopes.
Do digital telescopes exist?
No, digital telescopes don't exist. The telescope which we know are optical telescopes and what NASA uses are radiation based telescopes, or something related to radioactivity. As far I know, I've never heard about digital telescopes.
