Physicists and Astronomers

---

Duties

When it comes to their work, physical scientists and astronomers are known to:

• Discover new ways to explain natural phenomena, including gravity or the production of subatomic particles, with the help of scientific theories and models.
• Establish a plan for scientific research in order to verify ideas and find new characteristics of matter and energy.
• Prepare research ideas and submit funding requests.
• Investigate novel material characteristics or the existence of planets in other solar systems using mathematical computations.
• Make telescopes and lasers of the highest quality.
• Create data analysis and modeling software.
• Produce peer-reviewed articles for scholarly journals.
• Attend conferences and give speeches to disseminate your discoveries.

Researchers in physics study the underlying features and principles that govern the universe. For example, they may research theories and conduct experiments, or they may apply their expertise to the development of materials or equipment.

It's the job of astronomers to figure out what's up there in the sky. They employ both ground-based and space-based equipment, including as optical telescopes and the Hubble Space Telescope, for their research. These include black holes and neutron stars, which are studied by certain astronomers. Satellite activities might be jeopardized by space debris that is being monitored by others.

Applied research is a popular career path for many physicists and astronomers. They employ their expertise in fields such as energy storage, electronics, communications, and navigation to develop new technologies or address issues. Other researchers focus on developing ideas that explain notions like gravity or the origin of the world, such as the Big Bang theory.

Researchers in the fields of physics and astronomy frequently collaborate with engineers and other sciences. Team members' progress can be monitored by senior astronomers and physicists. Research money may also be a consideration for them.

To conduct experiments, physicists use equipment or sensors to gather data, construct theories, and test them. Computational and theoretical physicists come up with theories to explain or predict the behavior of materials. Even though the fundamental principles of physics are the same, physicists tend to specialize in one or more of the numerous subfields. 

Physicist job titles can include any of the following:

Researchers in the fields of atomic, molecular and optical physics investigate atoms, molecules, electrons, and light and their interactions. Some are looking for ways to regulate the states of individual atoms in order to further miniaturize or build new materials or technologies.

They employ algorithms, numerical analysis, and datasets to analyze how theories of physics interact with those of the real world. Astrophysics and applied phenomena like as ocean dynamics and traffic flow are being studied by researchers at the University of Texas at Austin.

Material and condensed matter Scientists in the field of physics investigate the physical characteristics of matter at the molecular, nanoscale, and beyond. In their research, they investigate a wide spectrum of phenomena, from superconductivity to liquid crystals.

They research radiation and its consequences on individuals, communities, and the natural environment. They ensure that radiation is used to its full capacity while safeguarding employees and the general public from radiation-related risks.

Physicians who specialize in medical physics use their expertise in physics to develop innovative medical technology and radiation-based therapies. As an example, certain cancer patients may benefit from safer radiation treatments. MRI and ultrasonic imaging, for example, are being developed by others as better methods of capturing radiant energy for imaging.

Quantum mechanics is concerned with the study of elementary particles like quarks, electrons, and nuclei and the forces that interact with them.

A separate state of matter known as plasma is studied by plasma physicists, whose work may be found in things like neon signs and fluorescent lights as well as in the stars and interplanetary space. In the future, these researchers may look into the possibility of using fusion reactors to generate electricity.

Information processing, computing, and encryption can all benefit from the utilization of quantum objects, such as atoms and photons. For them, quantum physics and its inherent uncertainty are a primary concern.

Astronomers, unlike physicists, are unable to conduct experiments on their objects since they are too far away to interact with. Astronomers, on the other hand, are more likely to conduct experiments or develop theories. Observational astronomers use telescopes to study the night sky and gather data. A theoretical astronomer studies systems and how they interact, as well as how they change through time.

 Here are some examples of astronomer jobs:

Cosmologists, extragalactic and galactic astronomers, planetologists, and stellar astronomers look into the origins, evolution, and potential futures of the universe, as well as its galaxies, suns, and planets. In their work, these astronomers explore new ideas and hypotheses, such as the string theory, theories of dark matter and energy, and simulations of galactic and stellar development. They also research how planets originate and interact with one another.

Optical as well as radio frequency for example, astronomers use telescopes to investigate the movements of stars, galaxies (and the cosmos as a whole), and the larger scale structure of the galaxy.

Biophysicists, chemical physicists, and geophysicists are examples of physicists who operate across disciplines. See the profiles of biochemists and biophysicists and geoscientists for further information.

Also, someone with a background in physics and/or astronomy can be professors or teachers. Check out our profiles on high school and college educators for more details.

Education

Research and teaching positions in the sciences often need a doctorate in a relevant discipline, such as physics, astronomy, or a closely related field.

Condensed matter physics and cosmology are examples of subfields of physics that graduate students might specialize in. Ph.D. students are required to take math courses including calculus, linear algebra, and statistics, as well as physics or astronomy courses. It is also possible to employ computer science to create programs that collect, analyze, and model data.

This degree is typically necessary to attend a master's or doctoral program in physical science or an area of study linked to physical science, such as engineering. Typical undergraduate physics courses include quantum mechanics, thermodynamics, and electromagnetics, among others.

Internships are a great way for undergraduates to obtain real-world experience. The American Astronomical Society and the American Physical Society both provide internship directories for astronomy and physics students, respectively.

Engineers and computer scientists often hire physics graduates as technicians and research assistants because of their training in the discipline. A job as an observatory assistant may be available to those who have earned a bachelor's degree in astronomy. Courses in instrument construction and computer science may be of interest to students who do not wish to pursue PhD degrees.

Jobs in the federal government may be available to those with master's or bachelor's degrees. Others may choose to teach science at middle or high schools, respectively.

Training

For those with a Ph.D. in physics or astronomy who want to work in the field, a postdoctoral research position might be a good place to start. Scientists in more senior positions keep an eye on these junior researchers as they develop expertise and autonomy through more difficult assignments.

Qualities that may matter

Critical thinking abilities. Physicists and astronomers must constantly review their own work and the work of others in order to avoid mistakes that may invalidate their findings.

The ability to communicate. Present their findings at conferences, in front of the public, and in any other way possible. In addition, they provide technical reports for publishing and research funding bids.

The ability to use critical thinking. When doing scientific tests and investigations, it is important for physicists and astronomers to think rationally. There is a need to verify the accuracy of the findings and conclusions

The ability to interact with others. Working with others is essential to the success of physicists and astronomers; consequently, they must be able to communicate effectively with their coworkers.

ability to solve mathematical problems. Calculus, geometry, algebra, and other mathematical concepts are used in physics and astronomy. Mathematical words must be used to describe their findings.

The ability to solve problems. Researchers in the fields of physics and astronomy utilize a combination of analytical and creative thinking to address complex challenges. In the event that an experiment or hypothesis does not yield the anticipated results, they may have to rethink their method and come up with other options.

Self-discipline. Scientists and astronomers who work with enormous datasets for extended periods of time need a source of inspiration to keep them going.

Registration, Licenses, and Certifications

If you want to work for the federal government, you may need to be a U.S. citizen and have a security clearance.

Pay

In May 2020, the average yearly salary for astronomers was $119,730. If half of the people in a profession make more than the median wage, and half earn less, we say that the median wage is too high or too low. Between the bottom 10% and the top 10% of earners, there was a wide disparity in income.

Job Projections

Physics and astronomy jobs are expected to rise at a rate of 8% between 2020 and 2030, which is in line with the overall average for all occupations.
