The Sun is our closest star and its study provides a window into the life and behaviour of many stars through the universe. We use it to understand the dynamics of magnetised plasmas, which are common throughout the universe not just in stars. However, to study the behaviour of stars, we only have the radiation that is emitted - which is typically in the form of photons. Hence, the basics of studying stars is related to counting photons. In this talk I will discuss some of the details of how we measure photons coming from the Sun and the statistical methods we use to extract information from the photons to infer the physical properties of the plasma within the Sun.
