This photo was taken at the Observatory in Dunedin while investigating Light Pollution. It shows light in different forms-the lights behind in the background of Dunedin City and the rainbow of lights in the foreground. The rainbow light is a robotic ball with an led light that was programmed to change colour. The camera's shutter was open for an extended time which captured the trail the ball made while changing colour, thus creating a rainbow star.

Incandescent light bulbs only work if oxygen is prevented from getting to the tungsten filament. This is achieved by enclosing it in a bulb of inert gas. If oxygen does get to the filament it burns up in less than a second.
