😆 Who ever told you that was either terribly misinformed or an outright liar. Space has no atmosphere (because it's space) as such it is by definition lacking in temperature.

If we put a thermometer in darkest space, with absolutely nothing around, it would first have to cool off. This might take a very very long time. Once it cooled off, it would read 2.7 Kelvin. This is because of the "3 degree microwave background radiation." No matter where you go, you cannot escape it -- it is always there.

The short answer is that the temperature in space is approximately 2.725 Kelvin. That means the universe is generally just shy of three degrees above absolute zero – the temperature at which molecules themselves stop moving. That’s almost -270 degrees Celsius, or -455 Fahrenheit.

The coldest place in nature is the depths of outer space. There it is 3 degrees above Absolute Zero.
NOW. what don't you understand??????
