The Coldest Place in the Universe is Here

Where is the coldest place in the universe ? The answer is the Boomerang Nebula (Boomerang Nebula), which is known so far the coldest objects, its temperature as low as minus 272 degrees Celsius, cold people can not imagine.

According to a report on the Live Science website, astronomers have measured the temperature of the Jarabo Nebula through the Atacama Large Millimeter-submillimeter Array in Chile to be minus 272 degrees Celsius ( Or minus 458 degrees Fahrenheit) considered as the coldest place in the universe.

The Jai Li Bang Nebula is a young planetary nebula , about 5,000 light-years away from the earth, with a dying star in its center. This is the creator of the nebula.


Over time, a star called a red giant will exhaust the hydrogen in its core and eventually collapse into a white dwarf, which is the very dense core remnant of the star.

When the collapse occurs, the outer layer of the star will be thrown down. This is because the red giant is very large and has weak control over the outer layer. When the light from the white dwarf illuminates the outer gas, it presents a brilliant planetary nebula to humans .

These gases are expanding outwards very quickly, and their outward movement speed exceeds 585,000 kilometers per hour. As the gas expands, they become colder. This is because the expansion will cause the pressure to decrease, which in turn slows down the movement of gas molecules, and thus the temperature drops. (The higher the temperature, the stronger the kinetic energy of the gas molecules and the faster the movement rate, and vice versa.)

That’s why Boomerang Nebula is so cold, it is even more than the universe big bang cosmic background radiation left over from the (cosmic background radiation) still cold.

As for the earth, the coldest place known so far is in the laboratory of the Massachusetts Institute of Technology in the United States.

In 2015, a group of physicists at the school used lasers to cool individual sodium and potassium atoms to a temperature of minus 273.15 degrees Celsius, which is colder than the Pelagic Rod Nebula. However, this is only limited to some atoms, and it does not occur naturally.

The earth’s environment is suitable for human survival and the existence of liquid water is allowed. The main reason is that the earth can receive the sun’s radiation, there is frequent movement inside the earth, and the surface is protected by the atmosphere. Without these necessary conditions in space, the temperature is naturally extremely low. According to the laws of physics, absolute zero is minus 273.15 degrees Celsius (or can also be recorded as 0 Kelvin), which is a state that cannot be achieved in theory. Even in seemingly empty space, the temperature is higher than absolute zero. The Cosmic Microwave Background (Cosmic Microwave Background) that permeates the universe makes the average temperature in space reach 2.725 Kelvin. So where is the coldest place in the universe? To reach extremely low temperatures close to absolute zero, careful design is required. Humans have created the lowest known temperature in the universe in a laboratory on the surface of the earth, and even lower temperatures may soon appear on the International Space Station in the Earth’s orbit. (International Space Station), this also marks another advancement in human exploration of the nature of matter.

The common material forms are solid, liquid and gaseous. In fact, under some extreme conditions, matter will show more peculiar states. For example, under extremely low temperature conditions, certain specific atoms will assume a state closer to a “wave” in the description of quantum mechanics. In the 1920s, Indian physicists Satyendra Nath Bose (Satyendra Nath Bose) and Einstein made a prediction that the boson atom (according to Bose statistics, there can be multiple atoms in Atoms of the same energy state) at a temperature close to absolute zero will present a gaseous, superfluid state of matter. This ideal state of matter is called Bose-Einstein condensate (Bose –Einstein condensate).
