The ISS will create the coldest place in the Universe
NASA experts will create the ISS the coldest place in the Universe to explore the quantum properties of atoms.
The experiment with the help of special instruments which atoms cooled to a temperature close to absolute zero, the article says Popular Science.
For these purposes, created project Cold Atom Laboratory (Laboratory cold atom), which includes all the necessary tools. All of them have already been sent to the International space station.
It is expected that the module will cool the gas to very low temperatures and to maintain low temperature longer than can be achieved on Earth. The researchers hope that once the equipment is installed at the station, she will be able to cool gas cloud to a temperature only 0,0000000001 of a degree above absolute zero.
Absolute zero — temperature limit, which can have a physical body in the Universe. At absolute zero stops the chaotic motion of atoms and molecules. Thanks to the combination of lasers and magnets the atoms in a new experiment will be cooled to a state of almost complete immobility. It is assumed that due to microgravity on Board the ISS such as atoms will last for 5-10 seconds.
Scientists say that the study of ultracold atoms could change everyone’s understanding of matter and the fundamental nature of gravity.
The experiment was originally planned in 2016, then it was moved to August 2017. The launch of the capsule held only on Monday, may 21, 2018. It is expected that the capsule will begin work after may 24. The experiment will be operated remotely from the Ground, not by astronauts on Board the space station. The laboratory will run the station for at least three years, and its service life can be extended.
While the coldest in the Universe is the object located in the boomerang nebula. Astronomers examined it through the telescope ALMA in Chile. Object 272,15 chilled to minus degrees Celsius, just one degree warmer than absolute zero.
