Question

Quizplus · Accepted Answer

Most of the mass of the Milky Way Galaxy is found in the form of dark matter, which does not emit light and is therefore not part of the luminous components of the galaxy such as the spiral arms, bulge, or galactic center. This dark matter extends far beyond the visible parts of the galaxy, contributing significantly to the total mass of the Milky Way.
