Everybody has heard about the Aurora Borealis, also known as the Northern Lights, but surely most of us don’t know how to explain exactly this amazing natural phenomenon. Auroras are the result of the emission of photons in the Earth’s upper atmosphere, from ionized nitrogen atoms regaining an electron, and oxygen and nitrogen atoms returning from an excited state to a ground state. This collision causes lights that can be green, yellow, blue, violet or red, and they can reach heights of up to 150 km.
the Northern lights are unpredictable. You can’t know for sure when they will appear, but it is known that the best time to gaze at this fantastic show is in Winter, especially in February and March. In order to observe them, we have to travel to polar regions, such as Alaska, Lapland or Greenland, and to wait until midnight, when the lights’ shine increases. Sometimes, the show only lasts a few minutes, but if you are lucky, you can enjoy this magical vision for several hours.
You must be patient
If you have scheduled to watch this profusion of lights, you have to know that patience is required. Don’t forget you are at the mercy of nature. Aurora Borealis likes to play hide-and-seek. The best you can do is to stay in a place where you are able to watch the lights for at least a week. In the end this wait will be rewarded with a show you’ll never forget, viewing these wonderful lights in the sky.
