Radio images reveal fast-moving electrons interacting with the galaxy’s magnetic field. They help us map atomic and molecular hydrogen and hot ionized regions. Infrared images show where starlight heats the interstellar gas and dust and reveal red giants, planetary nebulae, and young, massive stars deeply embedded in their parental molecular gas clouds. Visible light shows…
