The James Webb Space Telescope (JWST) provides a new window into exoplanet atmospheres with its unprecedented sensitivity and wavelength coverage. This has led to a wide range of exciting discoveries within the first three years of operation, including the discovery of photochemically produced chemical species in an exoplanet atmosphere. Discovery of photochemistry is particularly exciting as it provides the first observational evidence of stellar driven processes in an exoplanet atmosphere. This brings forward an important question,"How does stellar radiation shape the atmospheric properties of orbiting (exo)planets?” In this talk I will discuss some recent results and ongoing work of the exoplanet atmospheres group aimed at answering the above question, from gas giants to rocky exoplanet atmospheres.
