Hello SAURABH KALITA,

• A Bachelor's in Aestrphysics aims on making a student capable of studying the celestial bodies and their physical and chemical properties. Along with it, the course also explains about the natural phenomena occuring in the universe. 
• Specializations in an aestrophysics course are electromagnetism, thermodynamics, newtonian dynamics, optics, waves, modern physics, nuclear physics, atomic physics, quantum physics, solid state physics, fluid mechanics, relativity etc.
• The course is a three year full time undergraduate programme. Most of the colleges follow the semester system. 
• Basic eligibility is completion of 12th with physics, chemistry and mathematics. Along with this the institute level examinations and personal interview results determin a canditates eligibility.

Universities for B.Sc. in aestrophysics are:

• Osmania University, Hyderabad
• Andhra University, Vishakhapatnam
• Punjabi University, Punjab
• IIT Bombay, Mumbai
• Indian Institute of Science (IISc), Bangalore
• IIT Madras, Chennai
• IIT Delhi, New Delhi
• IIT Kanpur
• Tata Institute of Fundamental Research (TIFR), Mumbai
• Delhi University
• IIT Kharagpur
• Indian Institute of Space Science and Technology (IIST), Trivandum
• Indian Centre for Space Physics, Kolkata
• Savtribai Phule Pune University - Department of Atmospheric and Space Science, Pune
• Cochin Institute of Science and Technology - Department of Atmospheric Sciences, Cochin
• IISER, Bhopal
• IISER, Kolkata
• IISER, Pune

Some of the universities need you to appear for GATE and JEST examinations.

Career Prospects after completing graduation in aestrophysics:

• As a beginner you can work as a researcher on one of the existing research project. It will be hard to start you own research as being a beginner you will not get a lot of sponsors.
• You have an option of studying further. You can do your M.Sc. and Ph.D. The more you study the better will be your chances at research and securing better jobs.
• Most of the astronomers are under the employment of the federal government or under federally supported laboratories.
• National Aeronautics and Space Administration (NASA), Naval Research Lobaratory (NRL), Niels Bohr Institute, Naval Observatory, Space Telescope Science Institute, Nicolaus Copernicus are global organisations which recruit research scientists.
• The positions which you get hired for are observational astronomers, researcher, theoretical astrophysicists, solar astronomer, stellar astronomers, research assistants, technicians etc.

All the best!

I hope this helps!

Do revert back in case of any doubts.
