Astronomer Duties and Responsibilities

An Astronomer uses telescopes and space-based instruments to observe the planets, galaxies, stars and other celestial bodies. They study the origins of the universe, time, the life cycle of suns, black holes and others. Astronomers perform scientific experiments to prove theories, find properties of matter and different forms of energy. 

Here are examples of an Astronomer’s duties:

  • Plan, design and conduct observational experiments, as well as analyze telescope, radio and satellite data.
  • Develop computer models to test and prove theories of spaces processes.
  • Create and deploy software and instrumentation to observe and analyze space bodies and processes.
  • Collaborate with other Astronomers, Scientists, Technicians and Computer Engineers to design, develop, implement and maintain hardware and software products for astronomy.
  • Develop, deploy and update operational standards and guidelines for lab activities.
  • Test new equipment and operational guidelines of data gathering systems.
  • Supervise non-scientists with a detailed explanation of engineering and astronomical requirements during project execution.
  • Prepare reports on activities of teams, test performance and recommend strategies to improve results.

What Does an Astronomer Do?

Astronomers can specialize in a range of subjects related to space and the universe including theoretical astronomy, solar astronomy, planetary astronomy, stellar astronomy and galactic cosmology. Astronomers can work in a laboratory or classroom environment where they analyze data, or do fieldwork at an observatory where they can observe planets and stars using powerful telescopes and cameras. They collaborate with mathematicians and physicists to develop technology and contribute to current knowledge about the natural behavior of the universe and different heavenly bodies. They explain complex theories to their colleagues, write reports on their findings and give presentations on their research.

Astronomer Skills and Qualifications

A successful Astronomer will have various prerequisite skills and qualifications needed for their job duties. The right candidate will have a high-level of problem-solving skills and an in-depth knowledge of research and data analysis. They must be grounded in mathematics, physics and the sciences, proficient in science-related software programs and be able to work within a team. 

Here are common Astronomer skills and qualifications:

  • Ph.D. in astronomy, physics, mathematics or related field
  • 5-10 years’ in a postdoctoral research position
  • Excellent research skills and an ability to solve complex problems
  • Proficiency in using astronomy, mathematical and physics software packages
  • Data analysis and computer modeling
  • Strong communication and collaborative skills

Astronomer Salary Expectations

The data is not available for the average annual Astronomer salary. However, Astronomers are specialized professionals and receive excellent salaries. They often work in research institutions, universities, observatories, labs and other science-related fields. They can be Researchers, Professors, Civil Servants or Field Scientists. Pay varies based on seniority, the area of specialization, geographical location and employer, among other factors. 

Astronomer Education and Training Requirements

Depending on the position, Astronomers require a bachelor’s, master’s or doctorate degree in astronomy. Candidates can specialize in a specific area of astronomy including stellar and planetary physics, astrophysics, cosmology, optics and interstellar medium. They need a solid background in mathematics including calculus, statistics and algebra, and excellent computer skills such as data analysis and modeling. 

Top candidates will have postdoctoral research experience, especially when applying for industrial and government positions. They require an extensive knowledge of industry specific software tools to analyze and model data from ground and space-based equipment. Astronomers have to be proficient researchers and writers because they must consistently read, write, publish and present scientific papers at conferences. 

Astronomer Experience Requirements

A successful Astronomer will be an adept researcher and excel at solving complex problems. The job requires an excellent understanding of the fundamental principles of physics and mathematics and how they relate to the universe. 

Experienced Astronomers will have a good working knowledge of the industry’s computer programs to aid in the analysis, modeling and troubleshooting of data from multiple sources. They are also excellent communicators because their work requires seamless collaboration with several teams of scientists and engineers across different time zones. 

A great Astronomer will understand the different aspects of astronomy and how they can answer big questions about the universe and its elements.

Frequently asked questions about Astronomers


What are the daily duties of an Astronomer?

Astronomers can have different responsibilities depending on their field of study, but a typical day for an astronomer generally involves a few key duties. Astronomers may dedicate a few hours every week working with a telescope or teaching astronomy concepts in the classroom, but they spend most of their time at a computer using advanced software to analyze data on planetary movement and different phenomena. When working in the field, they make meticulous notes and take photographs so that they can share their findings with others.

Additionally, Astronomers read scientific research and new theories related to space so that they can stay informed on developments in their field and apply them to their research projects. They attend conferences to learn the latest updates and discuss theories, best practices and new technologies with their peers.


Who does an astronomer report to ?

Depending on where they work, Astronomers can report to senior colleagues in their field, a university director or their organization’s Chief Science Officer. As academics, Astonomers are highly collaborative with other scientists and may not always report to a superior in the workplace.


Where do astronomers work?

Astronomers work in three main environments: education, government and the private sector. Astronomers who enjoy teaching others about the universe can work at colleges, high schools and science museums, either full-time or in addition to a research-based position. Government-sponsored labs and observatories hire Astronomers to develop national intelligence, refine equipment designs and develop new research methods. Astronomers can also build a career working at aerospace firms and private consulting companies, providing scientific advice for projects related to space travel and satellite development.


Is astronomy a good career?

Astronomy is a good career for people who are interested in how the universe works, enjoy working out complex theoretical problems and like to spend time in academic settings. Long-term, being an Astronomer can be both financially lucrative and intellectually stimulating. Astronomers who work at a university have the option to apply for tenure, which gives them reliable job stability and academic freedom to study and teach the topics that they find most interesting and benefit their research career. People who are good at math, creative, inquisitive and analytical can make excellent Astronomers.
