The Sun, which is the nearest star to us, offers us valuable insights into numerous astrophysical phenomena. One of its most fascinating characteristics is the layers of its atmosphere, each with unique features and dynamics. The dynamics of the solar atmosphere are a complex interplay of various physical processes, with magnetic fields playing a crucial role in shaping different space weather phenomena, such as solar flares and coronal mass ejections that affect our Earth as well as the broader heliosphere. This seminar delves into the multifaceted nature of the solar atmosphere, exploring its various layers – the photosphere, chromosphere, transition region, and corona – and shedding light on their intricate interplay. In addition, the discussion will also emphasize the broader implications of solar atmospheric dynamics for space weather forecasting, satellite communications, and terrestrial climate, emphasizing the importance of understanding our nearest star.
