Question

Quizplus · Accepted Answer

Young O and B stars, dust, and gas are found in the spiral arms of the Milky Way Galaxy, outlining its structure. These components are significant in marking the spiral pattern because young stars, especially the hot and luminous O and B types, form in the dense regions of gas and dust within the arms. Globular clusters, solar-type stars, and white dwarfs are distributed differently within the galaxy and do not specifically outline the spiral arms.
