Light Telescopes

Why is the Hubble telescope located in space?

• So it can be closer to the stars it magnifies

• It has very large optical lenses

• So its images aren't distorted by Earth's atmosphere

• So it can be operated by astronauts

Why are many large optical telescopes located on mountains?

• to be closer to the stars

• to be above some of the atmosphere and further from city lights

• because it is easier to build telescopes on mountains

• to be closer to city lights
