Scientists make record for coldest temperature ever achieved
The coldest place in the world is considered to be the Vostok station of Antarctica. It is freezing cold here. The temperature here goes down to minus 89 degrees Celsius. Scientists have made a record of achieving the temperature cooler than the temperature here. Scientists have reduced the temperature on Earth itself to minus 273.15 degrees Celsius.
Scientists have done this feat by installing a tower 393 feet below the ground. This tower has been installed so that the temperature of the scientists and objects present in the above-ground lab is not affected by the temperature there. This study has recently been published in Physics Review Letters.
Vostok is the coldest place on our earth. But the Boomerang nebula is considered to be the coldest place in the universe known to humans. It is in the constellation Centaurus, which is about 5000 light years away from Earth. The average temperature here is minus 272 degrees ie 1 Kelvin. But now scientists have made even lower temperature than Vostok on Earth.
This feat has been done by the scientists of Germany. They were doing research on the Bose-Einstein condensate (BEC) quantum property. BEC is also called the fifth state of matter. It is a gaseous substance at a very low temperature. In the BEC phase, any object starts behaving like a big atom. It is so cold that even bones get frozen in it.
