Embark on a celestial journey as we delve into the captivating realm of auroras. These ethereal light shows, painted across the night sky, offer a mesmerizing spectacle that has left mankind in awe for centuries. From their scientific origins to their captivating beauty, we'll explore everything you need to know about these celestial wonders.
Auroras occur when charged particles from the sun interact with Earth's magnetic field. These particles, primarily electrons and protons, are steered by the magnetic field towards the polar regions, where they collide with atoms and molecules in the atmosphere. This collision process excites these atoms, causing them to emit light, giving rise to the breathtaking auroras that we witness.
