"nation" is part of "country". "physics" belongs to "science", and "mechanics" belongs to "physics". "galaxy" refers to an operating system composed of countless star systems and dust. "constellation" refers to a group of stars projected on the celestial sphere in similar positions. "galaxies" and "constellations" no obvious logical relationship.
