im not very smart, but this is how i understand it:

if you were about as far from the sun as we are now, and were hanging out naked in space, you would experience very fast moving particles eminating from the sun, slamming into you. they would heat you up very quickly, and if you were "mooning" the sun, you would very quickly have third degree burns on your back side.

due to the lack of pressure, you would most certainly embolize and i believe capilaries and things are supposed to burst. your body would actually retain heat since you dont have anything much to radiate it to, and you would keep getting hotter as the sun cooked you from the rear. but since there is no pressure in a vaccuum, you would freeze (i have seen videos of water in a vaccuum simultaniously boiling and freezing. bizzare.)

Things like the cells in your eyeballs (facing away from the sun) would explode as the water in them freezes and ruptures the cell walls. not that your eyeballs themselves would explode, but think of a serious case of freezer burn.
