make objects look closer than they really are. however, even with the biggest
telescope a star looks like only a point of light though this light carries very
useful 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 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
telescopes have mirrors six metres across. Astronomers use two main kind of
