Hello aspirant,

I am describing you in brief.

For becoming astronomers(as it is compulsory till under graduate) Read whole answer carefully.

You must have Math, Physics, Chemistry at 10+2. Biology or Computer Science should be preferred 4th subject.

At the undergraduate level, you could study:

• B.Sc. Astronomy & Astrophysics
• B.Sc. Physics
• B.Sc. Mathematics (or Math & Physics double major)
• Earth Sciences

At the postgraduate level, you could do M.Sc. Astronomy or Astrophysics. Finally, a Doctorate (PhD) is required, especially if you want to enter the academia and institutes like ISRO or NASA.

Those who are from the B.Tech. ( Electrical, Electronics & Telecommunication Engineering ) background, can also opt for MSc Astronomy.

For becoming astrophysist:-

You should follow the same path as described under how to become an astronomer until the undergraduate stage. Astronomy and astrophysics often blend elements of biology, chemistry and other sciences to better understand phenomena in the universe. So, Math and Science are essential till 10+2. Additionally, start becoming involved in a small way even in elementary and high school, by joining astronomy clubs, attending local astronomy events, taking free online courses in astronomy and astrophysics, and keeping up with the latest news on websites like NASA, Science Daily, Spacecom etc.

You could pursue the following at the Undergraduate level:

• Astronomy and Astrophysics
• Earth Sciences
• Physics & Math
• Computer Science
• Liberal Arts

Additionally, keep an eye out for any summer jobs or internships in math or science. At the postgraduate level (Masters and PhD), you must specialize in Astrophysics. Make sure to include courses in astronomy, computer science, mathematics, physics and statistics to have a wide base of knowledge.

hope this helps you

all the best for your future
