Auroras: el espectáculo cósmico desde el Sol a la Tierra

The video explains the natural phenomenon of auroras, known as Aurora Borealis in the Northern Hemisphere and Aurora Australis in the Southern Hemisphere. These light displays are caused by solar wind particles interacting with Earth's magnetic field, leading to collisions with atmospheric atoms. This process excites the atoms, which release energy as light when returning to their ground state. The colors of the aurora depend on the type of atoms involved, with oxygen producing red and green light, and nitrogen producing blue and violet light.

What is the Aurora called in the Southern Hemisphere?

• Aurora Australis

• Northern Lights
