Question

What is the coldest place in the universe?

Answer 1

The Boomerang Nebula is the coldest place we have found.

Explanation:

Apart from experiments in which we have artificially generated temperatures a tiny fraction above `0K`, (which would make the coldest place in the universe somewhere in Helsinki), the answer is probably the Boomerang Nebula, located about `5000` light years away in the constellation of Centaurus.

The rapidly expanding gas around the star system has caused the temperature to drop from the more normal background temperature of `2.7K` or so to about the `1K` mark.
