Abstract : Understanding the large scale spiral structure of the Milky Way remains a challenge owing to the location of the Solar system that lies within one of the Galactic arms. Galaxy models suggest the presence of a central bar, four major gaseous spiral arms, minor arms and few arm segments. In addition, Milky Way is also believed to contain sub-structures that are termed as spurs/feathers, often found in external spiral galaxies, that give the arms their clumpy or patchy appearance. With the latest sensitive and high resolution Galactic plane surveys, there has been tremendous advancement in unveiling the large scale morphological features extending from hundreds of parsecs to kilo-parsec scales. In this context, I will present some of the recent discoveries that redefine the current view of the large scale structure of our Galaxy.
