Astronomers say the Boomerang Nebula is the coldest place in the universe at one degree Kelvin (minus 458 degrees Fahrenheit). This object is located close to 5,000 light-years away.
At one point it was a star much like our sun,but now it’s near the end of its life, and it has started to lose several of its outer layers.
The outflow of gas from the nebula is cooling itself while it expands rapidly from the center. This is similar in principle to the way refrigerators use expanding gas to produce cold temperatures.
