If you can get away from most light pollution and gaze along the Zodiac during a moonless night, you can see the faint glow of the Zodiacal light. It comes from sunlight reflected off dust particles in the orbital plane of the solar system. I took this photo from the peak of Mauna Kea in Hawaii. In the center of the photo are the Pleiades and the constellation Taurus. At left is Orion.
