The interstellar medium, composed of gas and dust, absorbs and scatters visible and ultraviolet light, making it difficult to observe most of the galactic disk using these wavelengths. However, other wavelengths such as infrared and radio can penetrate the interstellar medium, allowing us to study the galaxy in different ways.
