Is it really -273 degrees?

Space is not a vacuum, it has hydrogen gas and it's at a low temperature. I believe the average temperature of space is between 2 and 3 kelvin. So that woul be about -271 degrees Celsius. That means that there are probably areas that get close to -273. The actual absolute zero is -273.15, so I suppose there could be parts of space that are -273.

It depends on how close you are to a star. For example, anywhere in or around Earth's orbit it would be about 250 degrees (F) in the sun, but hundreds of degrees cooler in the shade.
In deep space you are starting to get close, but not quite to absolute zero. There will always be some heat from stars or some particle zinging by at a high rate of speed. Still, I'd pack an extra sweater or two :-)

Space has no temperature. Temperature is defined as a property of matter. Space is a vacuum, devoid of matter, therefore by definition can have no temperature.
Objects in space will have a temperature, and what that temperature is will depend on where the object is and what it is made from.

Well, they tell me that nothing ever actually gets to absolute zero, but I suspect deep space is as close as you can get.
