What’s an aurora?
- The name ‘Aurora’ comes from the Latin word for sunrise or the Roman goddess of dawn.
- An aurora is a natural light display in the sky, usually of greenish color but sometimes red or blue.
- This natural phenomenon usually occurs in areas known as the ‘auroral zone’ near the poles of the Arctic in the north and Antarctic in the south.
- The effect is known as the aurora borealis (or the Northern Lights) in Northern hemisphere latitudes.
- In Southern hemisphere latitudes the effect is known as the aurora australis (or the Southern Lights).
- Aurora is caused by the collision of energetically charged particles with atoms in the high altitude thermosphere within our atmosphere.
