A SPECIAL STAR

Discover the remarkable structure and dynamic activities of the Sun. This guide provides insight into the various layers of the Sun, including the core, photosphere, chromosphere, and corona. Learn about significant solar phenomena like sunspots, prominences, and solar flares, along with the impact of solar wind and coronal mass ejections (CMEs) on Earth's magnetosphere. Understand how these solar activities shape our planet's environment and create stunning auroras. Join us on an enlightening journey to uncover the secrets of our star, the Sun.
