If you love space and astronomy, it would be worth it, but you will absolutely need to study math, math, and more math. According to the US Department of Labor, Occupational Outlook Handbook section on Astronomers and Physicists, (read the whole article hear, the sections below are just highlights - http://www.bls.gov/ooh/Life-Physical-and-Social-Science/Physicists-and-astronomers.htm#tab-1
Physicists and astronomers study the fundamental nature of the universe, ranging from the vastness of space to the smallest of subatomic particles. They develop new technologies, methods, and theories based on the results of their research that deepen our understanding of how things work and contribute to innovative, real-world applications.
he National Aeronautics and Space Administration (NASA) and the U.S. Department of Defense are two of the largest employers of physicists and astronomers in the federal government. The scientific research-and-development industry includes both private and federally funded national laboratories, such as the Fermi National Accelerator Laboratory in Illinois.
Physics research is usually done in small- or medium-sized laboratories. However, experiments in some areas of physics, such as nuclear and high-energy physics, require extremely large and expensive equipment, such as particle accelerators and nuclear reactors. Although physics research may require extensive experimentation in laboratories, physicists still spend much of their time in offices, planning, analyzing, and reporting on research.
How to Become a Physicist or Astronomer
Advanced mathematical skills. Physicists and astronomers perform complex calculations involving calculus, geometry, algebra, and other areas of mathematics. They must be able to express their research in mathematical terms.
Physicists and astronomers need a Ph.D. for most research jobs. Many physics and astronomy Ph.D. holders begin their careers in a temporary postdoctoral research position, which typically lasts 2 to 3 years.
A Ph.D. in physics, astronomy, or a related field is needed for most jobs, especially those in basic research or in independent research in industry.
A typical Ph.D. program takes about 5 to 7 years to complete.
Graduate students usually concentrate in a subfield of physics or astronomy, such as condensed matter physics or optics. In addition to taking courses in physics or astronomy, Ph.D. students need to take courses in mathematics, such as calculus, linear algebra, and statistics. Computer science classes are also essential, because physicists and astronomers often develop specialized computer programs that are used to gather, analyze, and model data.
The median annual wage for physicists was $106,370 in May 2010. The median annual wage for astronomers was $87,260.
Employment of physicists and astronomers is expected to grow by 14 percent from 2010 to 2020, as fast as the average for all occupations.
