We are all aware that our Galaxy, the Milky Way is a spiral galaxy. Where are we (Earth and our Sun) amongst the hundreds of billions of stars in our galaxy? I will touch upon the aspects that have led us to our current understanding of the Milky Way. Measurements of stars and nebulae along with an understanding of galaxy dynamics have proved to be immensely useful in building this picture. Even today, we do not know all the structural features of our home galaxy. It remains a challenge as we try to fully understand our Galaxy whilst being constrained to a specific location within it. I will also discuss the currently working GAIA mission whose ambition is to build the 3D structure of our Galaxy by measuring distances to a large number of stars very precisely.
