Individuals who use the principles of physics and mathematics to learn about the fundamental nature of the universe including the sun, moon, planets, stars and galaxies. They use research data to calculate the composition of galaxies, quasars, stars and planets and to measure radio, infrared, gamma, and x-ray emissions from extraterrestrial sources. Included are observational astronomers who study the stars and galaxies using equipment such as radio, optical, and x-ray telescopes, spectrographs and satellite-mounted television cameras with computer-controlled image intensifiers; and theoretical astronomers who work on developing theories from observations they make themselves or from those made by other astronomers. They develop mathematical equations derived from the laws of physics, and apply these equations to observations. Astronomers may also teach, program computers, build scientific instruments, and develop and write scientific reports to make their work available for use by other scientists. They may also apply their knowledge to solve problems in navigation, space flight and satellite communications; and to develop the instrumentation and techniques that are used to observe and collect astronomical data.
