Etymology
The word "aurora" has its origins in Latin. It is derived from the Roman goddess of the dawn, Aurora. In Roman mythology, Aurora was the goddess who brought light to the world each morning.
Meaning
The term "aurora" refers to a natural light display that occurs in the Earth's sky, primarily in high-latitude regions. It is characterized by bright, colorful bands or streaks of light that appear in the night sky.
Origin
Aurorae are caused by the interaction of charged particles from the solar wind with the Earth's magnetic field. When these particles enter the Earth's atmosphere, they collide with atoms and molecules, causing them to release light. The color of the aurora depends on the type of atom or molecule that is excited.
