How does the interstellar medium affect our view of most of the galaxy? It prevents us from seeing most of the galactic disk with visible and ultraviolet light. It produces so much visible light that it blocks our view of anything beyond it. It has no effect on visible-light observations, but prevents us from studying the galactic center with radio waves or x -rays. It absorbs all wavelengths of light.
