In 2007, scientists from the University of Florida started using one of the world’s largest telescopes to study outer space. What is one method that people do not use to make observations from a distance?

• using microscopes

• sending satellites into space

• studying electromagnetic radiation coming from outer space

• analyzing different types of radiation to produce images of very distant objects

Refracting telescopes use lenses. Reflecting telescopes use mirrors. However, both types of telescopes have something in common. How are both types of telescopes similar?

• They both magnify tiny nearby objects.

• They both reflect light that enters the telescope.

• They both concentrate electromagnetic radiation.

• They are both classified as nonoptical telescopes.
