Auroras: Northern and Southern Lights

This lecture explores the phenomenon of auroras, focusing on the differences between the northern and southern lights, how they are formed, and where they can be observed on Earth. The instructor explains the role of Earth's magnetic field in protecting against solar winds and how the composition of the atmosphere influences the colors of auroras. Viewers are guided on the best locations to witness auroras, such as near the Arctic Circle for the northern lights and in Antarctica or southern regions for the southern lights, with the optimal viewing period between November and March.
