could there be ammonia based lifeforms other than water based lifeforms in outer space?

Answer 1

It has a lot of potential. It shares the important hydrogen bonds and bent molecular structure (dipole moment too) with water. In much colder places in the universe, it would possibly handle metabolic solvent properties that water does here, as water could not under such conditions. Ammonia is also universally abundant.

The crystalline structure of solid ammonia is of great interest. If an amorphous ammonia ice, one lacking a crystal structure but more like a glass, exists, it might make for an ideal base for the development of basic and then higher order replicating molecules that would be ammonia-based DNA. It is a prime candidate after water.

Answer 2

Does biochemistry evolve in liquid ammonia? The relevant experiment transported from water is the way to find out,

Ammonia's critical constants are 132.4 C and 1660 psi. One could envision a large warm planet under high atmospheric pressure having reasonable "ambient" conditions for life. As long as it didn't freeze it might be workable.

Freezing is the bad thing. Frozen water floats on liquid water and so melts first thing on warming. Both frozen ammonia (-78 C) and ammonia-water eutectic (-97 C) are denser than their respective liquids. Oceans would freeze from the bottom up to create a permfrost planet if temps dropped that low.

Do the Miller experiment in steel apparatus under pressure to see if analogs of amino acids, fatty acids, nucleotides, and sugars appear - or what does appear in their place. Go on from there.

Answer 3

i would say yes ,if life could thrive in the salty oceans life prob could evolve anywhere

Answer 4

Use your imagination. No one knows.
