Theoretical astronomy is oriented towards the development of computer   or analytical models to describe astronomical objects and phenomena. Professional   and observe/ take pictures of the sky.

Other astronomers are employed by government agencies, like   the U.S. Naval observatory or the National Aeronautics and Space Administration (NASA). And   only a few work for companies in the aerospace industry. Astronomers must decide which   objects to observe and the methods and equipment they will use. They will have to schedule a   time at an observatory and record their observations, or they may have an assistant gather   data. After they have the data, astronomers then analyze these observations, out them into   hypotheses, or theories. When they do so, they use computers to help them complete the   many calculations required to develop complex hypotheses about space. They often specialize   in one area, such as the solar system, the sun or in the... [continues]
