This article excerpts low temperature from Sina's minus 10 degrees, it has already experienced a difficult cold, but such a cold is not worth mentioning throughout the universe. Can you think of what extent to the minimum temperature in the entire universe? Scientists tell you five cold poles in the universe.
Cold Mainland - Antarctic Snow Ice Strip: Cold Mainland - Antarctica
Winter Antarctic Swostk (Vostok) Ice Lake is the coldest place in the natural world, minimum temperature can reach minus 54 degrees Celsius. It is a reason why it is the most cold place on the earth.
One is the altitude of it. Averaged 2500 meters above Antarctica is the largest continent above the earth, and the thin air is lowered.
Another reason is that polar eddy currents. In the dark winter of the Antarctic, the polar vortex is rotated around the Antarctic continent, so that it is separated from the outside. This also makes the Wostok Bing Lake cannot be swapped with the outside world.
Although the Arctic also has a polar vortex, Eurasian continent and North America's high mountain gas stream on the Arctic makes the polar vortex the power is weaker, and the duration is more short than the South Pole.
Huge red ice plant - Mars
Trigella 4: Huge Red Ice Factory - Mars
More cold than Antarcticia is Mars Antarctic, minimum temperature reaches minus 110 degrees Celsius. Winter in the Mars Antarctic, extremely cold, causing carbon dioxide in the air to dry ice, causing Mars atmospheric pressure to reduce one quarter.
There are also four seasons on Mars, but Mars's winter is a cold, and even hard stones will be frozen. Mars Similar to the earth, there is also a tilted axis, making the northern hemisphere and the Southern Hemisphere more directly in the whole year. But Mars is more distinct than the earth, because Mars has an eccentric orbit.
Mars's near location is 43.5 million kilometers from the far place, and more coincidentally, when Mars Antarctic is in a winter solstice, Mars is also in its far place. Therefore, this red planet has a great contrast with the winter in winter, which is very cold in winter.
Severe cold hell - Pluto
Three of the ice belt: cold hell - Pluto
On the summer, Pluto is now in the summer, the temperature of Pluto is high in the year, and is about 200 degrees Celsius. Pluto's summer is equivalent to 20 years on the earth, except for other seasons outside the summer, it is equivalent to the Earth's 228, the air on this planet is also all frozen, covered on the surface.
The season of Pluto is as far as it is far from the sun. In the near location, it is 4.4 billion kilometers away from the sun. After 124 years of leaving the location, Pluto arrived at its far place and 7.4 billion kilometers away from the sun.
Although Pluto listened to it very cold, if it is compared with the "universe ice box" outside the 5000 optical year, it is already warm as spring.
Two Two Two: Super Ice - Boomerang Nebula
Bush makes the temperature of the nebula 272 degrees Celsius, which is the coldest place in the universe, and is become a "cosmic ice box".
In fact, the temperature of the nebula is only more than 1 degree of absolute zero (0.73.15 degrees Celsius). Absolute zero is the critical state of the temperature in the nature. Once the absolute zero degree, the atom will stop movement.
Causes the reason for the low temperature of the nebula can explain: We know that when the liquid in a sealed jar is forced to discharge, the temperature will be urgent.
Bush makes the nebula are running rapidly, and there is no heat source around, so the internal temperature is continuously declining, and finally reaches the state of the absolute zero.
The most cold place in the universe - US Sang Di National Laboratory, stopping the movement under absolute zero
The first cold zone: the most cold place in the universe - Sang Di National Laboratory
In the cold place in the universe, we have to return to the earth. A year ago, Sandia National Lab and the University of Columbia published a papers in the Science magazine, describing how they stop moving their molecules in the laboratory and colliding with each other ago. . According to physics principles, we know that if you want to stop exercise, you need very low temperatures. Physicists try to reach the temperature of 272.59 degrees Celsius in the experiment, which is the lowest temperature in the universe. (序)
