The gas Phosphine (PH_3 )has recently been discovered in the Atmosphere of the planet Venus, as Phosphine is associated with life, then this as excited scientists as to the prospect of finding some sort of life.

I am using Nitrogen here, but have been assured by STEMnet that this is acceptable to use in place of Phosphorus, as I don't have that atom available.
