The solar atmosphere consists of several layers surrounding the Sun. The main layers are the photosphere, chromosphere, and corona. The photosphere is the visible surface of the Sun, where sunlight is emitted. Above it, the chromosphere is a thin layer that can be seen during a solar eclipse, displaying a reddish glow. The outermost layer, the corona, extends millions of kilometers into space and is much hotter than the layers below it. The solar atmosphere plays a crucial role in solar phenomena, such as solar flares and coronal mass ejections, which can impact space weather and Earth's magnetic field.
