telescope

Definition

A telescope is an instrument that helps us to see objects that are far away. It does this by collecting light from the object and magnifying it.

Telescopes can be used to see objects in space, such as stars, planets, and galaxies. They can also be used to see objects on Earth, such as mountains and forests.

There are many different types of telescopes, each with its own purpose. Some common types of telescopes include:

Refracting telescopes: These telescopes use lenses to collect and magnify light.
Reflecting telescopes: These telescopes use mirrors to collect and magnify light.
Radio telescopes: These telescopes use radio waves to collect and magnify light.

Telescopes are an important tool for scientists. They are used to study the universe and to learn more about the objects that we see in the sky.
