Astrobiology is the study of evolution and history of universe- extraterrestrial life and life on Earth. This is a very tough field which has place only for the best professionals and researchers. It is good to see that you are preparing for this field right from class 11. For this field, you need to have knowledge about geology and be an expert in mathematics.BT you could take- Physics - Chemistry- Mathematics- Biology (As 5th subject)

Subject Choice for Astrobiologist




PCB (Physics, Chemistry, Biology)

- If you are looking to become an astrobiologist, choosing PCB in 11th grade would be suitable.
- This combination will provide you with a strong foundation in the key sciences needed for this field.
- Physics will help you understand concepts like planetary motion, gravity, and other important principles in space exploration.
- Chemistry will be essential for understanding the composition of celestial bodies and the chemical processes that occur in space.
- Biology will equip you with knowledge of life forms, evolution, and how life can exist in extreme environments, which is crucial for astrobiology.




PCMB (Physics, Chemistry, Mathematics, Biology)

- While PCMB also includes Biology, adding Mathematics to the mix might not be necessary for a career in astrobiology.
- Math is not a core requirement for astrobiology, and focusing solely on Physics, Chemistry, and Biology will be more beneficial.
- Eliminating Mathematics from your subjects will allow you to dedicate more time and effort to mastering the relevant sciences for this field.
- You can always opt for additional courses or certifications in specific mathematical concepts if needed in the future.




In conclusion, choosing PCB in 11th grade will be the ideal subject combination for pursuing a career as an astrobiologist. This will ensure that you focus on the essential sciences required for studying life in space and exploring the possibilities of extraterrestrial life forms.
