What observations demonstrate the existence of an interstellar medium?

It is very cold, but otherwise comfortable. You breathe deeply. Although there is no oxygen, the air pressure is quite tolerable and seems almost Earth-like (because it is mostly nitrogen)
Your vista includes the breathtaking sights of an ocean of liquid methane and methane-snow-capped mountains (although the atmosphere is very smoggy, and the visibility is limited). Your solar day is about 16 Earth days long. A large, ringed object seems to hang in your sky, never rising or setting; however, it does go through phases from new to full and back to new again with the same 16-day period as the rising and setting of the Sun.
