Hii

Becoming an astrophysicist requires training and skill in a combination of astronomy and physics. Students should identify prospective schools and maintain a high GPA in high school and concentrate on excelling in math, science, and computer.

Later take any degree in the above mentioned subject

Later you need to do research and apply for respective organisation

While

 Earning a bachelor's degree in physics, astronomy, astrophysics, mathematics, or engineering with a focus in a relevant area such as aerospace engineering is typically the minimum requirement to get an entry-level job in cosmology, such as Research Assistant.

Hope this helps
