Solar Atmosphere

The solar atmosphere refers to the layers of gases surrounding the Sun, primarily made up of hydrogen and helium. It consists of several regions: the photosphere (the visible surface), the chromosphere (just above it, where solar phenomena occur), and the corona (the outer atmosphere, extending millions of kilometers into space). The temperature and density vary significantly across these layers. The solar atmosphere plays a crucial role in solar activity, influencing solar flares and coronal mass ejections, which can affect Earth's space weather and impact satellites and electrical systems.
