Great question! It turns out that there is actually a coldest possible temperature of -273C. Nowhere natural in the universe is this cold – deep space has a temperature of -270C, for example.
The only places we can get that cold – to within a millionth of a degree of ‘absolute zero’, as we call it – is in our labs at universities using a technique called laser cooling. So the labs in universities like St Andrews, Strathclyde, Oxford and Cambridge (to name just a few!) are some of the coldest places in the entire universe!
