Jobs & Career
Astronomy is an amazing & a promising career for the students, those are interested in the mysteries of the universe.
A career in Astronomy is broadly divided as Theoretical or Observational though.
Theoretical Research career is typically involves doing Bachelors in Engineering or Technology or Masters in Physics with the basic knowledge in Mathematics & Physics. You can join Universities or Institutions for a Ph.D programme & obtain a permanent job.
Observation Research Career is wider because students have an engineering degree or have knowledge of computer systems & electronics are encouraged to apply for the graduation programme & allows doing an M.Sc by research prior to doing a Ph.D.
There are various job opportunities exists in public and private organizations like Bhabha Atomic Research Centre (BARC), Inter-University Centre for Astronomy and Astrophysics (IUCAA), NASA, Technology Information, Forecasting and Assessment Council (TIFAC) etc.
As a brilliant astronomer, you may be offered by space research centres like ISRO, NASA etc.
Interested people can also join teaching profession after the accomplishment of pre-requisite qualification.
As a beginner, you can work as a fellow researcher with the existing team who already working on an Astronomy project.
You can also get internships at the different centers in India that do astronomy such as IUCAA, ARIES, NCRA, etc.
An engineer with a BE or B.Tech degree can also enter in this field as a research scholar.
After completion of your degree in Astronomy, you can work as a research scientist with various research Institutions & big government organizations such as the Indian Space Research Organization (ISRO).
You can also work as a researcher in the leading observatories and Institutions in the USA.

B.Sc in Astrophysics is a 3 year Undergraduate course. And, to get admission in this course you need to pass in higher secondary school certificate exam from any recognized board and you must have physics and mathematics in your class 12th examination. You have to score minimum 50% marks in your class 12th examination. The eligibility criteria vary from colleges to colleges:
1 Tata Institute of Fundamental Research, Pune
2 Indian Institute of Astrophysics, Bangalore
3 Birla Institute of Technology & Sciences, Pilani
4 Punjab University
5 Indian Institute of Science, Bangalore
6 Raman Research Institute, Bangalore
7 Inter-University Centre for Astronomy and Astrophysics, Pune
8 National Centre for Radio Astronomy
9 Osmania University, Hyderabad
10 Andhra University
11 Institute of Fundamental Research, Tamil Nadu

Hello,
So, you are confused between if you can go to the ISRO or any space science after BCA, then let me clarify you that you cannot go just after BCA. The reasons are following:
(1) Indian Space Research Organization is the only organization in India which conducts all its space program. To enter in ISRO, you must have at least M.Tech in Computer Science or Information Technology. ISRO does not hire the candidates who are only graduates. And if they do then it's a very rare case. So, no chance to get admission there.
(2) ISRO wants the candidates who are specialized with the branches like Aerospace, Aeronautics, Astronautics, Electronics, computer science & IT, Remote sensing & Navigation, Communication, etc. In BCA, you will just get the basic knowledge of Computer Application, BCA is not the stream of core specialization in computer science. So, no chance to go there.
(3) Although, in Space Science Organization, there are huge vacancies for computer science and IT students. But don't ever think to go there with only your graduation degree and no work experience. They do have a ton of weightage on your work experience in a particular field. Through BC, if you can't handle their ultra complex software and programming features. You cannot encrypt the data as they want. So, there are a lot of things which you cannot do with just BCA.
So, I suggest you to do MCA after that from one of the premier institutions and have a lot of experience in any space science or related field. This might help you go get admission in ISRO.
Kindly upvote the answer if you feel satisfied.

Good luck.
