Hi there,

Hope you are doing well.

Choosing to study astronomy can be exciting and intellectually rewarding. However pursuing a career in astronomy generally  requires a strong foundation in physics, mathematics, and sometimes computer science.

Both the jee exam and the cet exam are for different purposes. Giving the jee exam will help you in getting admission in any engineering college and pursuing that degree further.

Also, you can give the cet exam and then pursue your career further.

Both the exams are generally not inclined to the astronomy but can later help you in gaining some important knowledge related to physics and astronomy. You can also study about this in further details by visiting the official websites of both the examination authority.

Hope this resolves your query.
