SUMMARY
Cosmic rays, primarily composed of protons, play a crucial role in heating molecular clouds, while hard X-rays also contribute significantly to this process. Unlike soft X-rays, which lack the energy to penetrate dense regions of molecular clouds, hard X-rays can penetrate deeper, facilitating heating. The optical depth of molecular clouds is substantial in the visible spectrum, which further emphasizes the importance of these high-energy particles in the heating mechanisms of such environments.
