Moreover, the Aurora can collide with gases into oxygen and nitrogen. That is why the colours of the Northern Lights would be different.

Why are the Northern Lights sometimes coloured differently?

We can see photos of the Northern Lights come in different colours. The colour of the Aurora depends on what gases the particles from the sun collide with and on how much energy is being exchanged. Science says different gases in Earth?s atmosphere give off different colours when they are very excited. Oxygen emits the colour of green and red which is the most common colour of the Aurora.
