This question needs no introduction. The delineation is also quite plain.
Whatever it is out there, far away in the space is a 9th house matter. So the intelligent lifeforms inquired about are represented by Mercury in Pisces. Pretty good symbolism: intelligent (Mercury) aliens/lifeforms somewhere in the galactic space (Pisces).
