Galaxy
A galaxy is any of the systems of stars and interstellar matter that make up the universe. A galaxy is composed of stars, stellar remnants, interstellar gas, dust, and dark matter that are all held together by gravity.
Nature has provided an immensely varied array of galaxies, ranging from faint, diffuse dwarf objects to brilliant spiral-shaped giants.
