The northern lights recently lit up UK skies this week, and some lucky stargazers also saw Steve, the natural rare phenomenon, that has only been seen in a select number of countries: the United Kingdom, Canada, Alaska, northern U.S. states, Australia, and New Zealand.
As the night gets darker quicker - and for longer - there are several natural phenomena to keep an eye out for that occur all over the world - in both the Northern Hemisphere and the South.
Many of these phenomena are bright and colourful, providing lucky viewers a once-in-a-lifetime opportunity to view what the Earth can offer in technicolour. Here is a list of some of the most spectacular natural phenomena in the sky.
5. Green Flash
Over the horizon, you can spot a green flash, Great Gatsby style. These occur just after sunset or right before sunrise when the sun’s rays are bent by the Earth’s atmosphere and last for a few seconds. Green flashes occur because the Earth's atmosphere can cause the light from the Sun to separate, or refract, into different colours. This is an incredibly rare sight and the best chance of seeing a green flash will come with a clear view of the horizon. | Bernard Friel/Education Images/Universal Images Group via Getty Images
6. Fogbow
Usually, we see a rainbow, but have you ever seen a fogbow? Fogbows, also known as white rainbows, form when sunlight interacts with water droplets contained in fog, mist or cloud. These tend to appear on foggy days and are seen in the same direction as a rainbow - the sun would be behind your head. | Met Office
