Introduction

A telescope is a device that allows you get a better 
look at far away objects by enlarging them. Your 
telescope is a type of telescope called a refracting 
telescope. Telescopes are the most important 
optical instruments in astronomy, the branch of 
science that deals with celestial objects, outer 
space, and the universe as a whole. Some 
telescopes are really famous, like the Hubble 
Space Telescope, which is out in space and sends 
back amazing pictures of very distant stars.

Telescopes have been around for 
about 400 years. We don’t know 
exactly who invented them. 
However, Galileo Galilei (who 
lived from 1564 to 1642) was the 
first person to explore the sky 
using the device. Among other 
things, he examined the surface 
of the moon and discovered that it had mountains and craters. This 
was an important step for astronomy.

Of course, your telescope isn’t just for looking at the night sky. You 
can also use it to look at objects on Earth in the distance that you 
would like to look at more closely. Scientists call this terrestrial 
observation (from the Latin 

terra = earth). But it can also be used 

whenever you are too far away from the action. So, for example, you 

can use your telescope if you are 
sitting high up in the stands at a 

soccer or baseball game and you 
want to have a closer look at the 
players on the field.

Have you ever wanted to be able to take a closer look 
at things that are far away? The Moon and stars, for 
example? Or a bird perched up in a tree? Or a boat 
sailing out on the open ocean? Now you can do all of 
this with the My Discovery Telescope!
