Coloured glows called auroras are common around the Earth's polar regions. They are caused by streams of particles from the sun that are attached to the magnetic poles as the particles hit the earth's upper atmosphere they cause atoms of gas to glow. Auroras can look like huge curtains hanging in the sky, slowly changing shape. Sometimes they are seen over a much wider area, particularly when the sunspot activity is high.
