Learn astrophysics with online courses and programs
What is astrophysics?
Astrophysics is an advanced field of astronomy that studies the physical properties and behavior of celestial bodies and the cosmos. It's a base for understanding how our universe works, from tiny subatomic particles to entire galaxies. Unlike traditional classroom-based learning, astrophysics requires researchers to observe cosmic phenomena on a massive scale using telescopes and satellites. By studying these observations and conducting experiments in space, astrophysicists gain insights into the fundamental laws of physics that govern our world.Footnote 1
Astrophysicists employ observational and theoretical techniques to explore various phenomena, including star formation and evolution, modern cosmology, dark matter, and plasma physics. As a multidisciplinary field, astrophysics often intersects with other areas of study like geophysics, which examines Earth's physical properties, and astrobiology, which explores the potential for life elsewhere in the universe.

Astrophysics course curriculum
Astrophysics courses typically cover a diverse range of topics, from the fundamental principles of physics and mathematics to specialized subjects. Some topics of study that a learner might encounter in an astrophysics course include:
Star formation and evolution: Learn about the birth, life, and death of stars, as well as the physical processes that govern their behavior.
Modern cosmology: Explore the origins and evolution of the universe, the nature of space and time, and the role of dark matter and dark energy in the cosmos.
Galactic structure and dynamics: Investigate the properties and behavior of galaxies, their interactions with one another, and their role in the large-scale structure of the universe.
Extrasolar planets and astrobiology: Study the formation and detection of planets outside our solar system, and the search for extraterrestrial life.
Plasma physics: Understand the properties and behavior of plasma, an ionized state of matter prevalent in the universe, and its role in astrophysical phenomena.
These courses can provide a solid foundation in the field, preparing students for advanced studies or careers in astrophysics. Some programs may also offer elective courses in related disciplines like engineering, allowing students to tailor their education to their specific interests and goals.
Explore astrophysicist jobs
Astrophysicists engage in various duties depending on their specialization and work setting. Common tasks include observing celestial bodies, developing and testing theories, and reporting findings in research articles or conference presentations. Besides working as researchers in universities or research institutions, astrophysicists can also pursue careers as:Footnote 2
Atomic, molecular, and optical physicists: These professionals specialize in the study of atoms, molecules, electrons, and light, as well as the interactions among them. They work on controlling the states of individual atoms to enable further miniaturization and contribute to the development of new materials or technologies.
Condensed matter and materials physicists: These physicists examine the physical properties of matter in molecules, nanostructures, or novel compounds. They explore a wide range of phenomena, such as superconductivity, liquid crystals, sensors, and nanomachines.
Plasma physicists: Plasma physicists study plasmas, a distinct state of matter that occurs naturally in stars and interplanetary space and artificially in products like neon signs and fluorescent lights. They may research ways to create fusion reactors as a potential energy source.
Cosmologists and extragalactic/galactic, planetary, and stellar astronomers: Cosmologists study the origins and evolution of the universe, while extragalactic/galactic, planetary, and stellar astronomers examine the properties and behavior of galaxies, planets, and stars. These professionals use observational and theoretical methods to better understand the cosmos.
Optical and radio astronomers: Optical astronomers focus on studying celestial objects and phenomena using visible light, while radio astronomers use radio waves to explore the universe. Both types of astronomers gather data from telescopes and other instruments to analyze and interpret the behavior of celestial bodies and their interactions.
Keep in mind that some of these positions may require additional knowledge or qualifications beyond an astrophysics degree. edX offers a variety of educational pathways for learners interested in advancing their knowledge in a variety of subjects, including bachelor's degree programs and, for more advanced learners, master’s degree programs. You can also learn specialized skills in individual courses and boot camps.
How to become an astrophysicist online
To become an astrophysicist, you typically need a strong foundation in physics, mathematics, and astronomy or a related field. Pursuing a bachelor's degree in one of these subjects is a good starting point. Some positions may require a master's or even a doctoral degree in astrophysics or a related field, depending on the complexity and level of research involved.Footnote 3
If you are interested in adding new skills to your resume, explore how online learning opportunities, such as a bachelor’s degree in computer science or a higher level master’s degree in data science can help you build the expertise and experience you need to pursue roles in this field. For accelerated options, a data analytics boot camp could also be of interest.
Keep in mind that each job is different, and individual employers may have specific hiring requirements. Online courses can provide a solid foundation in astrophysics, while more advanced degrees, such as doctoral degrees, may be necessary for certain research or academic positions. Be sure to explore bachelor's, master's, and boot camp programs to determine the best educational path for your career goals.
