For additional meanings of "Galaxy", please see Galaxy.

A galaxy is a dense grouping of stars, held together by powerful gravitational attraction. Because of the extreme distance between galaxies, most of the lifeforms known to science are in our home galaxy, the Milky Way. There has been limited contact with objects, forces and life from outside this galaxy, however.

The mission insignia for Apollo 17 in the 20th century depicted a galaxy in the design. (ENT: "First Flight")
