Coldest temperature physically possible is about -460F or -273C. That is absolute zero (0 K) which is the absence of thermal energy. Basically no atoms move at all. I don't think it is physically possible to remove all thermal energy, but they have gotten extremely close. Like to 0.0001 of a degree within absolute zero. That's called the Bose–Einstein condensate which was just on NOVA about 2 weeks ago.

Space is about 2.7K which is -454F, or -270C.

On earth coldest temp recorded was -89C, which is -128F or 183K in Antarctica. So -40 or -50 on the Canadian prairies isn't that unheard of.
