For centuries, humans have wondered about the existence of planets around stars, other than our own Sun. However, for the first time in human history we have the capability not just to find, but also to characterize these far away worlds, termed as “Exoplanets". In this talk I will show the astonishing variety of exoplanets that have been discovered and techniques used to find them. I will discuss how we study exoplanet atmospheres using the combination of remote sensing observations, 1D and 3D atmospheric models, retrieval techniques and thereby characterize them. I will also briefly discuss how modeling the atmospheres of exoplanets from first principles, aid in-depth understanding of different processes, in the past as well as present Earth. Finally, I will show our approach to answer one of the most fundamental questions of humanity, Are we alone in this Universe?
