Undoubtedly the Arctic is a mysterious place full of natural wonders that are not present anywhere in the world. To simply look at the sky in the Arctic night is a unique experience, for it’s a totally clean and clear atmosphere with a view of millions of stars, which would be impossible to admire in a hectic city with hundreds of skyscrapers, pollution and lit spaces.
Surely you have heard about the beautiful Northern lights. They’re certainly spectacular, but there are other works of nature which are equally striking.
It is also known as the midnight sun and it’s possible to observe it on the dates near the summer solstice that occurs between June 20 and June 22. This also occurs in the Antarctic continent but has some different characteristics.
In a northern polar day, the bright star is visible for 24 hours or more and although considered a polar phenomenon, the reality is that it also can be seen 90 km out of the Arctic Circle, so some human communities settled in these regions may have the experience of going to sleep to daylight.
The phenomenon contrary to polar day is known as polar night, where the sun is not visible for 24 hours or more. Not in all regions where this phenomenon occurs the sky gets completely dark; in some parts there is some twilight clarity that doesn’t fully illuminate or obscure the sky; this is known as polar twilight. There are some other types of polar nights that vary according to the positioning of the sun.
Aurora Borealis or Polar
Maybe we have heard more about the polar phenomena. These come in both southern and northern hemispheres, the southern are called aurora australis and the northern are known as the northern auroras, which we’ll explain next.
- Why does this happen?
It all starts at a million miles from the earth, that is, from the sun. The natural reactions of this massive star eject gas clouds that can reach our planet. If one of these gaseous masses does arrive, it collides with Earth’s magnetic field and results in a huge flash of light stretching a million miles away from the Sun. A cloud of solar gas can take two to three days to reach earth.
The northern lights can be greenish, reddish and yellow or blue; it all depends of the level of concentrate oxygen and nitrogen molecules they gather.
Note that this natural phenomenon can occur in any part of the year and any time of the day, but due to sunlight it’s almost impossible to notice its appearance.
- Does it generate any hazard for the eyes?
No. Seeing the aurora borealis poses no risk.
This is a common phenomenon in the sky and firm surfaces acquire a uniform color, making the contrast between the two to get lost. The white floor and strong winds that disperse the snow through the sky is very common in such regions. This has misled researchers and airplanes, because the ability to measure heights or distances is lost, which is very dangerous.
These are some of the most amazing and unique arctic phenomena, where everything can be seen more clearly thanks to the purity of the air. Far from being just a place covered with snow, the Arctic is a wonderful place full of unusual entertainment for our eyes.
