Antarctica--in particular, the Russian station Vostok, at which a record- setting low temperature of one hundred and twenty-eight point six below zero Fahrenheit was recorded in nineteen eighty-three.
In nineteen-o-eight the university of Leiden made history by producing the first super-cooled helium. Guess how cold liquid helium is?
Four hundred fifty-two degrees below zero Fahrenheit.

Antarctica, a land of extremes, is the coldest part of the world. It is the coldest, windiest, and highest continent on earth. Near the center of Antarctica, summer temperatures don’t normally get above zero. Winter temperatures typically hover around 70 below. The lowest temperature ever recorded on earth, 126.9 degrees below zero, was in Antarctica.
Why is the continent so cold? There are a number or reasons.
Its latitude takes much of the blame. The sun’s rays strike the polar areas low in the sky, delivering less energy than they do in areas closer to the equator.
Altitude also comes into play. Antarctica is three miles above sea level. For every 1,000 feet above sea level, the temperature drops 3.5 degrees.
The East Antarctic Ice Sheet is the thickest, largest piece of ice anywhere on earth. Scientists have compared its thickness to the height of the Alps Mountains, which also are 3 miles high.
Dr. Keith Mountain, climatologist at the University of Louisville, says the continent stays frozen because 90 percent of the sunlight hitting the continent is reflected off of the snow and ice, and “melting snow takes an incredible amount of energy.”
Although it hardly ever snows there — about 6 inches per year — Antarctica is covered with miles of ice and snow, enough to account for 90 percent of the world’s ice.
Water temperature in the surrounding seas averages 29 to 33 degrees.

One would intuitively think the two poles two should be the lower temperatures places, that the closer one gets to them the lower it gets, but this is not so. In the north polar regions, the coldest place is not at the North Pole but near Verkhoyansk in Siberia where the lowest recorded temperature is -94°F. Extreme cold is experienced here because Verkhoyansk lies in the middle of a large land mass which can cool in winter much more than the Arctic Ocean where the North Pole is located. It can also heat up much more in summer than the ocean can. As a consequence, temperatures can fluctuate from +98°F to -94°F, the greatest yearly range experienced anywhere on earth. In meteorological terms the climate of Verkhoyansk is referred to as continental, while the North Pole climate is considered to be maritime despite the sea ice that covers the Arctic Ocean. Similarly, Fairbanks' climate is classified as continental while that of Anchorage and Juneau is maritime.

Antarctica is the coldest place on earth. The lowest temperature ever recorded on earth was −89.4 °C recorded in 1983 at the Russian Vostok Station in Antarctica. This is still higher than the lowest temperatures achieved in cryogenic labs. Moving away from the earth, the coldest temperature found in nature is the Boomerang Nebula, at about one kelvin, which is cooler than the cosmic microwave background radiation.
