The word aurora comes from the Latin “aurōra” which refers to brightness, radiance, dawn or dawn; and this from the Indo-European root "aus" which means "brightness of the rising sun", from which words like "austral", "Austria" and "Australia" also originated. The word aurora has several possible meanings, one of which is the most used to describe that pink light that appears in the sky just before sunrise. On its side is the Aurora that emerges at the poles; It is a glow that manifests itself in the night sky of the northern hemisphere. This phenomenon is called the Aurora Borealis; and in the southern hemisphere this phenomenon also appears, which is called Aurora Austral.

These occur when the charged particles of electrons and protons that emerge from the sun, which are directed by the magnetic field of the Earth and impinge on the atmosphere near the poles. When these particles collide with the oxygen and nitrogen atoms and molecules in the air, part of the energy of the collision, thus generating a light that is shown in the earth's iosphere.

It should be noted that this phenomenon is characterized by different structures, shapes and colors that change over time; and at night they can start as a long isolated arc that expands on the horizon, usually in an east-west direction.

Another possible meaning of the word aurora is used to describe the beginning or beginning of something in particular.

On the other hand, aurora is called a drink whose components are almond milk and cinnamon water.

And finally, a religious-type song that is recited at dawn, shortly before the rosary, with which the celebration of a festival in the church begins, is also called aurora.
