Who Are You Calling Exo?

exosciences (also xenosciences) (n.): Including exogeology, exogeography, exoclimatology, exobiology, exoecology, exosophontology, exomemetics, etc.

An archaic series of terms referring to the various sciences when applied to off-planet phenomena, usually used with reference to the speaker’s homeworld.

This terminology fell into rapid disrepute after the first full conference of the Fellowship of Natural Philosophy after the reunification of the Thirteen Colonies, in which, upon entering the nomenclaturical dispute over the proper terminology to describe each individual colony’s branch of the exosciences – then in its third hour – Academician Excellence Corvis Ejava, Dean Pro Tem, declared “it’s a big [redacted] galaxy and none of your homeworlds are that [redacted] special”, adding that the prospect of having to use 300 billion different terms to describe the same studies depending on where you were was “the single most bloody stupid thing I’ve heard in the last 900 years, and I have students”.

The term geography, while possessed of some local bias, persisted for several hundred years after this conference, before being universally replaced with galactography, following representations from the scientific community of the hydrogen-breathing sssc!haaaouú that while their homeworlds could be described as many things, “geo-“ was not one of them.
