information about the star. The light waves can reveal the make-up of the star and how hot the star is. A
telescope also receives the whole range of radiations like radio waves and X-rays given out by a star.
Astronomers do not see through the telescope. Instead they use them
as big cameras to take photographs of the night sky. Telescopes use curved mirrors to collect the light. The
largest telescope have mirrors six meters across. Astronomers use two main kinds of telescopes. They
differ in the way collect and focus the light from the stars. A reflector is a kind of telescope that uses mirrors and
the refractor is a kind of telescope that uses lenses.
