They certainly do.  Just what do you think the temperature in space 
is?  Heat is energy.  By Einstein's E=MC^2, energy is equivalent to 
mass.  Space is totally massless, hence it is without energy, hence 
there can be no heat.  The fact that photons carry radiated energy 
(or are pure energy, we'd have to get into the quantum world to 
really discuss that), this partially accounts for the minuscule rise 
above absolute zero - that and the background radiation - now in the 
microwave range.  Also, at space station orbit, there are remnants of 
atmosphere which can absorb and re-emit energy, but again, at a 
minuscule level - likely just above the quantum level.  An 
over-simplification, but quite pertinent, is the homogeneity of space 
(granted, on a cosmic level, but still applicable) the temperature is 
pretty darned constant.  The actual glitches in that homogeneity are 
at the galactic level.
