Hi Anvay,
Good to see that you have an interest in Ethical Hacking and Security profession in early days.
However, to become a white hat hacker to work with a company to safeguard their infrastructure and intellectual property from internal or external threat you need to go through professional course like Ethical Hacking. Later on you may get a certification from EC council.
It's not necessary to get certified by CISEH and CPTE but important is CEH for EC council and if possible CISSP. These two courses cover all kind of hacking related technologies, skills and processes. It's up to you if you would like to get certifications of CISEH and CPTE.
Another Important aspect is you need to understand first about Infrastructure and different areas like Computing, Storage and Networking and how they have put together to run an IT. In early stages you might be curious about EH but in reality you need to earn expertise, experience towards when and where you are going to apply what EH knowledge.

Those who opt for the astronomy field, should pass their plus two examination under the science stream, specially in physics and math's. For pursuing a career in theoretical or observational astronomy one may go through the science stream after plus two. Since universities offering undergraduate programme in Astronomy are rarely found, one can join for a major/ honours in Physics with Mathematics as a subsidiary subject. Thereafter, take a master's degree in Physics or Astronomy. After the successful completion of M.Sc, one can do specialization in astronomy leading to Ph. D. which enables one to become an astronomer/ astronaut/ astrophysicist or a scientist/ research officer etc. in the field of space research.
