Telescopes How They work

Telescopes help us see things that are far away.

But how do they work?

A basic telescope uses two lenses, just like magnifying glasses, to help us see objects that are far away.

Why do we need to learn about telescopes if we are talking about space?

Telescopes help us take beautiful pictures of space like this one.

Light

Telescopes use light to make something small appear big. The two lenses use the light around you to make the object you are looking at look bigger.

Some telescopes can be huge!

This is NASA's telescope. It is called the Hubble Telescope.

Some telescopes can be small

No matter their size, all telescopes have two lenses and use the light around them to make a small or far away object appear larger.
