Most of people think of <astronomers> as people who spend their time in clod <observatories> (peering) through telescopes every night. In fact, a typical astronomer spends most of his or her time analyzing data and may only be (at the) telescope a few weeks of the year. Some astronomers work on (purely theoretical) problems and never use a telescope at all.# p& X- P6 h* U2 l7 c1 X
3 }# P& C& m2 p8 YYou might not know how (rarely images are viewed) directly through telescopes. The most common way to observe the skies is to photograph them. The process is very simple. First, a photograph (plate is coated) with a light-sensitive material. The plate is (positioned) so that the image received by the telescope is recorded on it. Then the image can be developed, enlarged and published so that many people can study it.! y, S/ B" O/ B/ [- p' W+ z& \) w
6 v# Y3 I. l3 gBecause most astronomical objects are very remote, the light we receive from (them is rather feeble). But by using a telescope (as a) camera, long time exposures can be made. In this way, objects can be photographed that are a hundred times too (faint) to be seen by just looking through a telescope.7 t: f* r! u) U& D, @- F
