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 were in Earth's home galaxy, the Milky Way. There was limited contact with objects, forces, and life from outside the Milky Way, however.

The mission insignia for Apollo 17 in the 20th century depicted a galaxy in the design.
