Instead of saying “minus” temperatures, I think meteorologists and other scientists (and people in reporting) should say “negative” to express negative temperatures. “Minus” is better to use for subtraction. Saying “degrees below zero” would be (is) better than saying “minus”.
-274ºC is when the neighbours up here say, “Getting a bit cold, eh?” At -300ºC Heck freezes over and the Toronto Maple Loafs win the Stanley Cup. Go Knights!!!!
A vacuum has no temperature. Without the movement of mass there is nothing to measure. Things loose heat in space, where there is no out side heat source, by infrared radiation, and they cool towards zero Kelvin.
In physics, nothing can ever get down to 0 Kelvin, because thermodynamics tells us there is no way to remove heat from a super-cold object that is getting close to zero. Any interaction with anything else will always impart a bit more heat to the super-cold object, so there is always a tendency to warm up, not to cool down all the way to zero.
Think of how hot that had to be to “pre-heat” an entire Universe to 2.74 degrees Kelvin.
Note: Kelvin degrees are the same as Celsius, only shifted so zero is absolute zero. (Kelvins and degrees Kelvin are used interchangeably for this reason.)

The good old cosmic microwave background. When TV sets were analog, you used to be able to pick it up as static.

It doesn’t help that all those stars are heating up the whole place.

Boy, this “absolute zero tolerance policy” concerning open doors of parents all over the universe “alienates” me…

And I’m complaining that it’s close to -40 here.

Aha. The real for global warming is universal warming eh.

You just can’t win with those young ‘uns. They’re either leaving the door open or slamming it shut.

She angrily slammed the door shut, resulting in a big bang.

Space is 2.74° Kelvin? I guess I can wear a lighter coat. (Er? how large is a Kelvin unit?")

As a kid, I would accidently leave the door open and my mother would scream “DO LIVE IN A BARN?”
I would just say “MOOOOOOOO”.

I also assumed that the heat released from all of those stars might contribute.

Well so much for an open door policy.

Yikes! And that’s without the solar wind chill.

To paraphrase: "Space is cold. You just won’t believe how vastly, hugely, mind-bogglingly cold it is. " ;)
