Reputed institutions like Indian Institute of Astrophysics, Sri Venkateswara University, etc. Offer this kind of master level courses. M.Sc programs on streams of astrophysics, astrometeorology, astrometry, astrobiology, astrogeology, etc. are also suitable to build up a career in astronomy.
Step 3: Search for a career in astronomy
After completing educational programs related to Astronomy, candidate can search for a lucrative career in the field. At entry level one can get in to the role of Junior Research Fellow, Research Trainee, etc. Job positions exist in firms like NASA, Association of Bangalore Amateur Astronomers (ABAA), Bhabha Atomic Research Centre (BARC), and Indian Space Research organisation (ISRO). Department of Science and Technology, Government of India also offer enough career openings. Inter-University Centre for Astronomy and Astrophysics (IUCAA), Technology Information, Forecasting and Assessment Council (TIFAC), etc. are some other firms offering rewarding jobs in this field.
