2010-09-02 Carbon Monoxide: Hot Water Around Giant Carbon Star Creates Interstellar Mystery Wired ScienceThe star the water vapor was found around is much like our star will be in 6 billion years: nearing the end of its life, expanding outward, and with more carbon than oxygen in its atmosphere. Water vapor wasnt expected around such a star, because it was thought that all the oxygen would be bound up in carbon monoxide, a stable molecule, and not available for making water molecules.

Breaking these molecules apart would release oxygen that could react with the abundant hydrogen to form water.
