Question

Quizplus · Accepted Answer

Molecular clouds, massive stars, and atomic gas are all preferentially found inside the spiral arms of the Milky Way. The spiral arms are regions of enhanced density, acting as sites for star formation where molecular clouds are more common. Massive stars often form in these regions and are found there. Atomic gas is also a significant component of the interstellar medium in spiral arms, contributing to the formation of new stars.
