Astronomy

Take maths and science classes all through high school. Make sure to take a wide variety of science classes. Astronomy and astrophysics often blend elements of biology, chemistry and other sciences to better understand phenomena in the universe. Also, keep an eye out for any summer jobs or internships in math or Science. Even volunteer work can help bolster your resume. Pursue a math- or Science-related Bachelor's degree. While a Bachelor in astrophysics is the ideal, there are many other paths to that field. You can do undergraduate study in computer Science, for example, which is important to help you analyze data. It's best to speak to your high school guidance counselor or local university to find out what degree programs will help you. Take on research opportunities. Many universities have labs in which students participate in discoveries and sometimes even get published.

Hello Amal Das, You have given list of all very interesting, the latest specialisations and asking for scope. Okay. Let me attempt. Astrophysics is comparatively old subject and it's scope is limited to research and hence if you are really fascinated & interested in research, you should not venture. Data Science has tremendous scope in the times to come. AI of course goes hand in hand with data Science and is being increasingly used. Biotechnology too had very good potential in India keeping in mind the requirement of increasing productivity of our farmers. Nanotechnology is another subject which promises great things but is yet to prove it's mettle. But don't go by what I am saying. Follow your heart, go for the subject that fascinates you the most. Best wishes to you.
