Stars play an important role in the Universe. They are the luminous building blogs of galaxies and one of the major drivers of their evolution. Through feedback mechanisms like Stellar Winds or Nova events, they enrich their surroundings and provide the elements needed for the formation of life in planetary systems like our own Solar System. In this presentation we will look at the formation and evolution of the star in our own Solar System, the Sun. We will explore the Suns interior structure and the processes allowing the Sun to produce energy. We will talk about how solar processes effect life on Earth and give an outlook on the upcoming Total Solar Eclipse, which will be observable from parts of the USA in April 2024.
