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.
Mammatus Clouds
Mammatus Clouds are some of the rarest and most distinct clouds that take the form of a series of bulges or pouches emerging from the base of a cloud. They are formed in association with large cumulonimbus clouds, where turbulence such as thunderstorms in the cloud will cause Mammatus to form. These clouds can be seen in the UK, but are a rare sight and are most visible when the sun is low in the sky.
