Very cold: We usually use the Kelvin temperature scale, where Zero Kelvin is this "absolute zero" temperature -- or -273 degrees C. Water freezes at +273 Kelvin and water boils at +373 Kelvin.
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.

It would be really cold. Temperature measures the energy per "degree of freedom" (i.e. way something can move) of whatever molecules happen to be around. So, it it becomes so cold that the molecules stop all together, then this is the "absolute zero" temperature. On the Celsius Temperature Scale (i.e. water freezes at 0, and boils at 100) this takes place at -273 degrees C.

While there is no limit to how hot things can be------"How hot is hot?"-------the depth of "cold" does have a limit. At a temperature of - 273.15 degrees Celsius, all molecular motion would cease (that's at a little more than 459 degrees below zero Fahrenheit.)This temperature is referred to as "Absolute Zero".
While attaining this temperature is an impossibility, you can theorize coming as close to it as you like. This would be the lowest possible temperature in the center of one of the Supergalactic "bubbles" which make up the grossest detected structures of the cosmos.

The temperature of the universe immediately after big bang was about a billion degrees and after 13 odd billion years it has slowly cooled to somewhere around 2.75 Kelvin.
gues this s good enuf??

Brood question there. Unless where ever out in space has a system like do (clouds, water sun etc) I would think it would be just dead space.
Never been there myself lol!

cold enough to freeze your nads off. Unless you get too close to a star, in which case you will singe the hairs off your nads

It gets hot too

a touch above absolute zero
