| | Physicists and astronomers |
 | | Astronomers who make observations with ground-based telescopes may spend long periods in observatories; this work usually involves travel to remote locations and may require long hours, including night work. |
 | | Although physicists and astronomers are employed in all parts of the country, most work in areas in which universities, large research and development laboratories, or observatories are located. |
 | | The work of physicists and astronomers relates closely to that of engineers, chemists and materials scientists, atmospheric scientists, environmental scientists, geoscientists, computer systems analysts, computer scientists and database administrators, computer programmers, and mathematicians. |
