This is a composite of six images taken at around midnight in June. Each exposure was about 20 minutes long to gather enough light to be properly exposed. The star trails above the canyon attest to the long exposures and prove that the earth is moving relative to the stars. Polaris, the North Star, appears stationary because the axis of the earth is aligned with it. The light came from a partial moon. The colors are essentially the same as they would be in the daytime because moonlight is just reflected sunlight. The sky is blue and the grass is green but our eyes just aren't sensitive enough to see the color at night.
