Question

Quizplus · Accepted Answer

Giant molecular clouds of H₂ and CO gas are primarily found along the spiral arms of the Milky Way Galaxy. This is because the density of gas and dust is higher in these regions, providing the necessary conditions for the formation of molecular clouds. Additionally, the spiral arms contain young and massive stars that release large amounts of UV radiation and other energetic particles, which can trigger the collapse of molecular clouds and the formation of new stars.
