Why is the Hubble telescope located in space?

• So it can be closer to the stars it magnifies

• They have very large optical lenses

• So its images arent distorted by Earth's atmosphere 

• So it can be operated by astronauts 

What are some of the characteristics of a good location for building a telescope?

• Calm air

• Clear skies (few clouds for most of the year)

• Dark skies (far from cities)

• Dry

What does Reflecting Telescope have?

• Lens

• Mirrors

• Bat ears

What type of telescope is shown in this image?

• Newtonian Reflector

• Cassegrain Reflector

• Keplernian Refractor

• Galilean Refractor

What does Refracting Telescope have?

• Sand

• Mirrors

• Lens

• Batmobile 

Why are many large optical telescopes located on mountains?

• to be closer to the stars

• to be above part of the atmosphere

• because it is easier to build telescopes on mountains

• to be closer to city lights

Radio telescopes biggest advantage is that they:

• Can be used during the day

• Can be used in any type of weather

• Almost all radio waves make it to the surface

• All of these

Why must Ultra-Violet observing be done in space?

• The ozone blocks most of the UV rays in the surface.

• It’s hard to know exactly where the ozone hole will be to find UV images

• It’s hard to use UV telescopes and radio telescopes together on the surface.

• It’s hard to use UV X-Ray telescopes and radio telescopes together on the surface
