The Aurora Australis impressed Tasmanians this week with a colour show we won't forget. Lucky stargazers saw the night sky awash with eerie coloured lights in vivid greens and pinks.
What causes the Aurora phenomenon? Here's a quick rundown:
- The sun emits charged particles called electrons.
- When this 'solar wind' makes contact with the Earth's magnetic field, the charged particles are funnelled towards the North and South Poles.
- The particles strike gases high in the atmosphere.
- When the gas molecules return to their normal state, they emit photons, bursts of energy in the form of light.
- Oxygen will give off a greenish-yellow and red light, while nitrogen emits a blue light.
Photographers, professionals and amateurs, took advantage of the stunning colours visible to the naked eye. Here's some of their work:
