Question

Quizplus · Accepted Answer

Observations of the Milky Way and other galaxies indicate that most stars form within clusters in the spiral arms. This is because spiral arms contain a high density of gas and dust, which is needed for star formation to occur. Studies have shown that most stars in the Milky Way have formed in clusters in the Galaxy's spiral arms. These clusters are known as open clusters and contain hundreds of young stars that formed from the same cloud of gas and dust. Over time, these clusters can disperse as the stars move away from each other, but the majority of stars form in this manner.
