The cosmos is icy. But where is the coldest?

Recently, an astronomical winter has begun in the northern hemisphere of our planet. However, even the coldest places on Earth appear innocent in comparison with the coolest planets and other objects in the universe.

Cold records

The lowest temperature recorded directly on the Earth's surface is -89.2 degrees C. The measurement was made at the Vostok station in Antarctica on July 21, 1983. In August 2010, satellite observations showed a temperature of -93.2 degrees C (East Antarctic ice sheet, ridge between Dome A and Dome Fuji station). However, this result was not universally recognized as a record because the measurement was made indirectly using satellite remote sensing methods. Satellite observations show, however, that in this region the temperature can drop to almost minus 100 degrees Celsius. Such a temperature drop takes place when it is summer in our country, while in Antarctica it is polar night.

In recent years, we have already got used (unfortunately) to media reports on heat records related to climate change. According to the Copernicus Earth observation program, each month of 2020 was in the four hottest months in history. The summer of 2021 was also exceptionally warm, breaking previous records by 0.1 degrees Celsius.

This does not mean, however, that it is getting warmer everywhere and always on Earth. The weather is much more complicated. In December 2021, winter also saw itself in all its glory in many places in the northern hemisphere. The lowest temperatures were recorded in the far north of the Russian Federation. In the city of Delyankir it was -61 degrees C, which sets a new cold record in December in this region of Russia. It was also freezing in the north of Canada - there the temperature dropped to -46 degrees Celsius, which gives the highest December temperature drop in the Canadian Arctic in 15 years. Another cold record (-43.8 degrees C) was broken last year and in Sweden. It is true that in its far north, in the town of Naimakka (where only one person lives permanently), but also in this case it was the lowest temperature recorded there since 1944.
