Astronomers who are sometimes called astrophysicists study matter and energy throughout the universe including the sun moon planets stars and galaxies. To accomplish this they use space-based ground-based optical gamma-ray X-ray and radio telescopes.
Some astronomers develop instruments and techniques that will be used to collect astronomical data. Others are more concerned with conducting analyses on the information gathered with these new computer and telescope technologies and then applying mathematical models and theories of physics to interpret it. Yet others may focus on applying this information to the solution of practical problems related to navigation space flight and satellite communications. Get a degree in satellite communications.
Astronomers are found in many work settings and they are seldom unemployed. Many are on the faculty and staff of colleges and universities where they teach and conduct research. Some work in observatories planetariums or museums where they communicate with the public. Yet others are employed by government agencies such as the U.S Naval Observatory or the National Aeronautics and Space Administration (NASA).
Astronomers may also work for the aerospace industry and a few even become general science writers. Aspiring astronomers are usually expected to hold a doctoral or Ph.D. degree in physics or a related field.
According to Payscale.com salaries for astronomers range from approximately $60000 to $108000 per year.
