Astronomy is a fascinating field that explores the vast expanse of the universe and beyond. Within the field of astronomy, there are many different specializations, each with its unique focus and set of primary duties. From planetary astronomers who research and analyze planets in our solar system to cosmologists who study the origins and evolution of the universe, each type of astronomer plays an important role in advancing our understanding of the cosmos.
In this article, we explore different types of astronomers and examine the primary duties of each specialization.
What is an astronomer?
An astronomer is a scientist who studies celestial objects such as stars, planets, galaxies and black holes. Astronomers work in a variety of settings, including universities, research institutions, observatories and government agencies. They may work individually or as part of a team on their projects. In addition to conducting research, astronomers also play an important role in educating the public about astronomy and the universe. They may give lectures, write articles, or participate in public outreach events to share their knowledge and passion for astronomy with others.
Types of astronomers
According to Glassdoor, the average salary for all types of astronomers is $59,785 per year. The list below includes 8 types of astronomers and a description of their primary duties.
1. Planetary astronomer
Planetary astronomers research and analyze planets, their atmospheres and other celestial objects within our solar system. They work to understand the formation, evolution and characteristics of these celestial bodies by using data gathered from telescopes and spacecraft. They also examine the potential for habitability and the possibility of life on other planets. Planetary astronomers may also work on the development and design of spacecraft and instruments used for exploration.
2. Galactic astronomer
Galactic astronomers study the structure, composition and dynamics of galaxies and their components, including stars, gas and dark matter. They also investigate the formation and evolution of galaxies over time. Galactic astronomers use telescopes and other observational tools to accumulate data and analyze it to answer fundamental questions about the universe. Additionally, they work on theoretical models and simulations to better understand the behavior of galaxies and the larger universe.
Cosmologists survey the origins, evolution and structure of the universe as a whole. They use observations of the cosmic microwave background radiation, the distribution of galaxies and other phenomena to create and critique theories about the nature of the universe. They also work to understand the fundamental forces and particles that govern the behavior of the universe, like dark matter and dark energy.
4. Solar astronomer
Solar astronomers look at the sun, its behavior and its effects on the Earth and other planets. They use telescopes and other instruments to observe the sun and analyze its features, such as sunspots, solar flares and coronal mass ejections. Solar astronomers also investigate the physics of the sun, such as its magnetic fields and how they affect the behavior of the sun’s plasma.
5. Optical astronomer
Optical astronomers survey celestial objects using visible light and other wavelengths of light that the human eye can detect. They use telescopes and other instruments to gather data points and analyze them to better understand the properties of stars, galaxies and other celestial objects. Optical astronomers work to understand the physical properties of the universe and attempt to understand the behavior of magnetic fields, the distribution of dark matter and the formation of stars and galaxies.
6. Exoplanet astronomer
Exoplanet astronomers research and analyze planets outside of our solar system. They use a variety of techniques to detect and watch exoplanets, such as the transit method and the radial velocity method. Exoplanet astronomers work to understand the properties of these planets, like their size, mass and composition. They also investigate the potential for habitability and the possibility of life on exoplanets. Exoplanet astronomers may also work on developing new techniques for detecting and characterizing exoplanets.
7. Radio astronomer
Radio astronomers examine celestial objects using radio waves. They use radio telescopes and other instruments to seek specific information from the sky and analyze it to better understand the properties of space. Radio astronomers investigate the physics of the universe, such as the behavior of magnetic fields, the distribution of dark matter and the formation of stars and galaxies. Some other focuses in this role may be on advancing techniques for learning about the universe using radio waves.
Astrophysicists observe the physical properties and behavior of celestial objects, including stars, galaxies and black holes. They use a variety of techniques to analyze the data they gather from telescopes and other instruments to improve models and theories about the universe. Astrophysicists work to understand the fundamental laws of physics that govern the behavior of these objects and the universe, as a whole.
Educational requirements for all types of astronomers
Here are some of the educational requirements that all astronomers typically complete before working in the field:
To become an astronomer, it is essential to have a strong foundation in mathematics, physics and computer science. Therefore, during high school, students can focus on taking courses in these subjects to prepare for higher education. Additionally, taking part in science clubs and competitions can help develop research skills and provide exposure to the field of astronomy.
To pursue a career in astronomy, you often obtain a Bachelor’s degree in astronomy, physics or a closely related field. During their undergraduate years, students take a variety of courses that cover topics such as astrophysics, planetary science and observational astronomy. Additionally, undergraduate students may participate in research projects with professors or work as an intern in a research institution to gain hands-on experience.
To become a working astronomer, students often pursue a Ph.D. in astronomy or another graduate degree within the same field. During graduate school, students often can conduct independent research, attend conferences and collaborate with other aspiring astronomers. They take advanced courses in areas such as cosmology, astrophysics and data analysis. After earning their Ph.D., aspiring astronomers typically complete a postdoctoral fellowship or research position to gain additional research experience before securing a permanent job.
