Hey ru hi,

Astrobiology is an interdisciplinary field. In order to become an astrobiloger you may do your B.Sc in any of the following fields based on your interest.

• Microbiology
• Geology
• Biology
• Botany
• Biotechnology
• Physics
• Chemistry
• zoology
• Astrophysics
• Astronomy
• Oceanology

I would probably suggest you to do Bsc in botany. This is one of the best for doing it and you may easily get that in most prominent colleges of du like hansraj, hindu, lady shri ram, Miranda, etc.

Read astrobiology-related scientific journals, which will help you to make your career better.

Hope this helps!
