Ammonia World by Ittiz Ammonia World by Ittiz
I haven't posted anything in awhile so I did a rendition of a planet with ammonia as the solvent rather than water.

The ammonia oceans, if it were just ammonia, would probably appear blue just like water. However unlike water ammonia can dissolve alkaline earth metals as if they were salt. When this happens the color changes. Dilute amounts of metal give it a an intense blue color, slightly higher concentrations give it a gold bronze color as shown here.

The reddish orange color in the atmosphere is due to oxides of nitrogen (nitrogen analogs for oxygen). Like Earth the atmosphere is primarily diatomic nitrogen. Unlike earth it contains next to no free oxygen, but has nitrogen oxidizers. Most probably nitrous oxide, but it could be nitric oxide. It's hard for me to figure out which would be more likely.

The planet would be much colder than Earth so I depicted the vegetation as black to collect more light. Unlike water worlds like Earth, plants on ammonia worlds wouldn't need to deprotonate water molecules to get an electron for photosynthesis. This is because the dissolved alkaline earth metals release free electrons which can be used directly. This would free up photosynthetic plants to use a wider range of the spectrum. This would probably free up hundreds of millions, if not a billion, years of evolution for photosynthesizing cells. However overcoming the diatomic nitrogen build up would probably more than make up for time gained.

Finally ammonia clouds and ice are white just like water.

I could probably use this planet as a death chamber for Terran criminals so if they breathed on a planet like this, they would subsequently die.

Wouldn't there be also be some abundance of methane in gaseous form? (NH3 vs CH4) Wouldn't that affect the atmospheric coloring? I honestly don't have an idea here; it's just that both are simple organic molecules, and since your planet is obviously a rocky body (accounting for the carbon) and the obvious abundance of hydrogen, I just figured that methane would be the analog here to Earth's oxygen (percentage wise, I mean).

In the image I made the oxygen analog would either be nitrous or nitric oxide. Both of which methane would burn in. Methane may probable would have been abundant in the early atmosphere, as it was with earth, but after oxides started to be produced in large quantities the hydrocarbon compounds in the atmosphere pretty much all reacted.

So you could still breathe even on an ammonia world?

Only if you'd like a quick painful death. Breathing in Earth would probably kill Ammonia life forms as well, if they didn't fry to a crisp first.

You know that nitrogen oxide can refer to a binary compound of oxygen and nitrogen, don't you?

I know that an ammonia world would have very little oxygen, but I could probably use an ammonia world as a death chamber for human criminals so if they breathed on an ammonia world, they would either subsequently die or get eaten by ammonia lifeforms as their penalty.

I wouldn't.
