Since it doesn't have anything in it, why does it absorb heat?

Heat is transferred in space by radiation. Since there's not much out there, any typical part of the sky 'looks' to be at about a couple tenths of a Kelvin. That's why things get 'cold' when you're in deep space.
In close to the Sun it's a different story. You absorb more heat (from the Suns radiation) than you lose, so it gets hotter.

Heat is the movement of molecules. The faster they move, the hotter the substance is. Since there are no molecules in space, it cannot conduct heat at all. The only way heat can be transferred though a vacuum is through radiation, which is how we get heat from the sun.
