No I don't think it is.....didn't you see that shuttle astronaut working in space take his suit off to work in his tee shirt because he was getting too hot.....he should of applied a 450 SPF sun blocker to.....I'll bet he had quite the sun burn after that......

That question is not as easy to answer as you think.
Firstly it depends where you are. The coldest it can be in space is 3K the hottest say just outside the Corona of a super massive star is going to be about 3 million degrees.
Now the to the tricky question of what hot and cold is.
Temperature is the measure of random kinetic energy in a mass. Where as heat is the rate of exchange of energy. Now the space around the earth has a high temperature (millions of K) but the matter is at such a low density that energy is radiated from say an space ship, faster then energy is conducted to the space ship from that matter surrounding it so space "appears" cold.
And to answer the question - depends on where you are and how you wish to define cold.

It depends on where.
The thing about space is, there's not much around - it's a vacuum. And as your thermos bottle demonstrates, vacuum is a very good insulator. Therefore, wherever you are in space, you aren't going to lose heat too quickly.
In fact, the only way you do lose heat is by light radiation. For the same reason that burning embers or light bulb filaments glow, you yourself glow, though not with any light you can see. (As a point of fact, you glow in the infrared - some night-vision goggles exploit this to see people in the dark.) Eventually, though, if you stay in space long enough, the energy from the light you emit will cool you down to a minimum temperature.
What is that minimum temperature? It depends on the other factor in the equation: how much heat you receive from radiation.
Light shining on you heats you up. This is obvious when you walk from the sunshine into the shade here on earth. Basically, therefore, the temperature of space is defined by this: the temperature at which the heat you get from the light shining on you exactly balances the heat you emit.
This temperature will vary, though, depending on where in space you are. Clearly in sunlight will be hotter than in the shade. However, far away from any stars or other hot matter, the temperature of the light shining on you can be reduced to one factor: the background radiation from the Big Bang. The temperature from this is 2.725 Kelvin, equal to -270.4 degrees Celsius or -454.8 degrees Fahrenheit.

The temperature varies depending on whether you are in view of the sun or not.
If you are in shadow and cannot see the sun, then the temperature that you will experience will be (Ignoring contributions from any planet you are orbiting, which can be very significant) slightly above absolute zero (0° kelvin, -273° Centigrade or -459° Fahrenheit)
If you are in view of the sun however, the temperature you experience will be due to the thermal infrared radiation emitted by the sun, which will actually depend on what color you are painted! Since there is no atmosphere, there is no conduction or convection, and the temperature is only a function or how good the material is at reflecting light.
The tempratures produced can vary widely between a few degrees to 100° C.

That's kind of a vague question since outer space is so vast. Parts of it are very cold with no reflected heat, other parts can get incredibly hot. It's really dependent on where in space you are.
According to an article I read many years ago, there will be parts of outer space where one half of an object will be cold while the other (facing a star for example) would be warm.

Empty space itself cannot have a temperature, unless you mean some
abstruse question about quantum vacuums.
However, if you put a physical object into space, it will reach a
temperature that depends on how efficiently it absorbs and emits
radiation and on what heating sources are nearby. For example, an
object that both absorbs and emits perfectly, put at the Earth's
distance from the Sun, will reach a temperature of about 280 K or 7 C.
If it is shielded from the Sun but exposed to interplanetary and
interstellar radiation, it reaches about 5 K. If it were far from all
stars and galaxies, it would come into equilibrium with the microwave
background at about 2.7 K.

Sure, there is no reflected heat. However, if you go near the sun you will find it is quite warm. You mention 'space' but, you see, space is quite large. It might be a good idea to specify which part of space you mean, at least to, say, the nearest 10 cubic miles.

Yes its cold in space.

The Gas Law [PV=nRT] states as volume of gas decreases so does temperatre. As space is a vacuum i.e. there is no volume of gas [V=0] then T is as low as possible i.e. as close to absolute zero [-273C] as possible. The suns rays will keep things in space warm, but general its pretty brass monkeys out there.

Yes VERY VERY cold-there's no sound in space either!
