Earth’s rotation makes it day in some places and night in others. But what happens at the poles, where sunlight hits very differently from the rest of the world? The answer is experienced by several thousand people living in towns within the Arctic Circle each year. A very long night is about to begin: in some cases no less than six months.
During this half year, in areas close to the North Pole, thermometers will show really cold temperatures, and many cities and towns will have to surrender themselves to an environment that will be truly hostile to the rest of the planet.
polar night It is formed due to the combination of the Earth’s translational and rotational motions, as well as the planet’s elliptical orbit around the Sun.
Because of all these motions, once a year the Earth’s tilt causes the Sun to stay below the horizon at the North Pole, initiating the polar night. The sun doesn’t literally rise during the polar night; It should be noted that the degree of darkness varies depending on the area where this phenomenon occurs; that is, the penumbra is not total in all regions.
The closer you are to the North Pole, the darker it will be, in parts further away from this; there will be more moments of clarity.
At the autumn equinox, on September 23, the polar night will begin at the North Pole. It will be six months without seeing the sun, especially until the arrival of the spring equinox, when an endless polar day with 24 hours of light will begin.
The reverse situation at the South Pole
While this happens in the north, the opposite happens in the southern hemisphere. It is there from the moment when the ‘polar days’ of uninterrupted light will begin. As the Meteored.com portal recalls, these situations always occur during the winter months, lasting from September to March in the northern hemisphere and from March to September in the southern hemisphere.
If we want to experience this interesting phenomenon for ourselves, there are several cities in Alaska, Sweden, Greenland, Russia or Norway that we must travel to observe. In the second country, especially The remote archipelago of Svalbard in the middle of the Arctic OceanFrom the 23rd, especially from November to January, the sky will be in ‘night mode’. More and more tourists visit Svalbard not only for this phenomenon, but also to enjoy the magnificent Northern Lights.
Inside Alaska is a town of 4400 inhabitants named Barrow.Neighbors gather around November 20 each year to observe the last sunset of the year. This town bids farewell to the sun for more than 60 days, until the next January 23, the king star will appear on the horizon again. The activity of this region almost completely ceases during this time, and a large part of its population moves to other places during these two months.
Nurmansk is a populated place in Russia.It is the largest located within the Arctic Circle (295,000 inhabitants) and is a strategic enclave for coal extraction that has been out of sunlight for about 40 days. It is a slightly shorter ‘polar night’ as it is slightly further from the North Pole than the others.
