21100 – Physicists and astronomers
Physicists conduct theoretical and applied research to extend knowledge of natural phenomena and to develop new processes and devices in fields such as electronics, communications, power generation and distribution, aerodynamics, optics and lasers, remote sensing, biotechnology, medicine and health. They are employed by electronic, electrical and aerospace manufacturing companies, telecommunications companies, power utilities, university and government research laboratories, hospitals and by a wide range of other processing, manufacturing, and research and consulting firms. Astronomers conduct observational and theoretical research to extend knowledge of the universe. They are employed by government and universities.

Develop or participate in the development of instrumentation and software for astronomical observation and analysis.


Employment requirements
Physicists usually require a master's or doctoral degree in a field of physics, engineering physics, or in a related discipline.
Astronomers usually require a master's or doctoral degree in astronomy or in a related discipline.


Additional information
Astronomers may specialize in fields such as astrophysics, observational or optical astronomy and radio astronomy.
Mobility between specializations within physics and within astronomy is possible with experience.
Mobility is possible to the fields of meteorology, geophysics and other fields of science.
Physicists may specialize in fields such as aeronomy and space, acoustics, atomic and molecular physics, biophysics, condensed matter or solid state physics, electromagnetics, fluids and aerodynamics, health physics, medical physics, metrology, particle physics, optics and laser physics, nuclear physics and plasma physics.
Physicists may work closely with and perform some of the duties of engineers.
Progression to management positions is possible with experience.
