An astronomer is a physicist who studies astronomy. These scientists study extraterrestrial bodies like planets, stars, and galaxies. Astronomers can be either professional or amateurs. Most professional astronomers have a doctorate in their discipline of study.
Astronomers like to use professional grade telescopes and instruments that help them in their research work and in making new discoveries. They also use planetariums, space observatory data and modern radio telescopes. Astronomers love stargazing and reading the latest developments in astronomical research. To appreciate the cosmos, amateur astronomers often take their telescopes to unrestricted sites and even invite others to explore the skies and get an up-close look of the galaxy.
