Astrophysics is the study of the planets, the Sun and other stars, the Milky Way Galaxy and the other galaxies, the interstellar medium and intergalactic medium, and the Universe itself.
This study is aided by our knowledge of the laws of Physics discovered by experiments carried out in laboratories.
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.
Astrophysics is an interesting degree but, at the same time, it can be challenging.
One of the hard aspects is reading and analysing research and data from the NASA website, with all the complex calculus and advanced research.
