Astronomers study celestial objects such as stars, planets, galaxies, and the universe as a whole. They use telescopes, satellites, and other instruments to observe and analyze these objects, seeking to understand their origins, evolution, and properties.

Space scientists study the universe beyond Earth's atmosphere, including phenomena such as black holes, dark matter, cosmic rays, and the origins of the universe. They use a variety of observational and theoretical techniques to explore the cosmos and advance our understanding of fundamental physics and astronomy.

Astrophysicists study the physical properties and behavior of celestial objects such as stars, galaxies, and black holes, using principles of physics and mathematics to understand the universe's fundamental processes.

Observatory technicians play a crucial role in the operation and maintenance of astronomical observatories and their equipment. They are responsible for ensuring that telescopes, cameras, and other instruments are functioning correctly, troubleshooting technical issues, and assisting astronomers with observations and data collection.

Planetary scientists study planets, moons, asteroids, comets, and other celestial bodies to understand their composition, formation, and evolution. They use a variety of techniques, including remote sensing, laboratory analysis, and computer modeling, to investigate the geology, atmospheres, and potential for life on other worlds.
