Not really. Pigments tend not to do so well in vacuum.
SquareDisc City wrote:but to grow an organism needs to take in matter, and space is known for its lack of such.
Very much so.
SquareDisc City wrote:Now an atmosphere-less planet is another mater. Provided there's a suitable solvent life could exist.
Underground, perhaps. But not on the airless surface itself.

The liquids would flash-boil too quickly for anything more complicated than the most basic hydrocarbons to form.
SquareDisc City wrote:The organism's skin and general physiology might well be designed to minimise fluid losses; perhaps it could be waxy like certain plants.
Wouldn't work - the pressure of the water would be too strong in anything of macrological size and the organism would rupture.

And of course it can't breathe, it would have to take in everything it needs from either solid or liquid substances.
The fact that it's metabolism is restricted to chemolithoautotrophy means that the most sophisticated lifeform that could possibly evolve is pond scum.

Well, ran off them.
The aliens in Blindsight were based on organic chemistry. A hardier version than ours, but still following the same principles.
