00:00Can you imagine that for the residents of this tiny town, night lasts 111 days during winter?
00:06This phenomenon is called the polar night, and people living near the Earth's poles can spend
00:10several months without sunlight. But why is that? As you know, the Earth spins on its axis,
00:17making day and night take turns. The side facing the sun has day, while the other side experiences
00:22night. But the thing is, the Earth's axis is tilted at an angle of about 23.5 degrees. And look,
00:30now some areas don't get any sunlight at all. These are polar nights, and they happen in a region
00:35called the Arctic Circle. But because the Earth also orbits the sun, it means that during the
00:40opposite time of year, when the Earth is on the other side of the sun, these areas have several
00:45months without night. This is called the polar day. It's interesting that no country lies entirely above
00:51the Arctic Circle, but many cities with permanent populations are located in this area. The closer
00:56a city is to the pole, the longer its polar nights and days will be.
