What is the coldest place in Universe?
The coldest place in the Universe is Boomerang Nebula, located in the constellation Centaurus, approximately 5,000 light-years from Earth. It has a temperature of around -458 degrees Fahrenheit (-272 degrees Celsius), which is only one degree above absolute zero. Its extremely cold temperature is due to the rapid expansion of gas expelled by a dying star in two opposite directions. As the gas expands, it cools rapidly through adiabatic cooling, reaching temperatures close to absolute zero.

The Boomerang Nebula was first discovered in 1980 by astronomers using the 15-meter Swedish-ESO Submillimeter Telescope in Chile. Its temperature was later measured in 1995 using the James Clerk Maxwell Telescope in Hawaii. The discovery of the Boomerang Nebula was significant in Astrophysics as it provided a unique opportunity to study the properties of matter at extremely low temperatures and shed light on the processes of stellar evolution.
The study of the Boomerang Nebula and other similarly cold regions of space has also led to advances in the field of cryogenics, which involves the study of the behavior of matter at low temperatures. Its discovery led to the creation of Bose-Einstein condensates, a state of matter in which atoms or molecules behave like a single entity. Such condensates have been used to study superfluids and other exotic materials and to create atomic clocks with unprecedented accuracy.
