To become an astrophysicist, start with a bachelor's degree in physics, ideally from a school with astrophysics research opportunities. Engaging in research experiences, such as REU programs, during your undergraduate years can help confirm your interest in the field. While some universities offer specialized astrophysics degrees, a general physics degree provides more flexibility for potential career changes. For graduate studies, pursue a Ph.D. directly, as this is the standard path in the U.S. You can earn a master's degree along the way, but standalone master's programs typically do not lead to a Ph.D. Focus on institutions with strong astrophysics research and consider a degree in applied mathematics, as proficiency in math is crucial. Building relationships with professors can enhance your chances of entering competitive graduate programs, but be aware that job opportunities outside academia are limited.
