One very special feature of the planetarium is the high abundance of areas which glow in the dark. This is because of special materials which absorb sunlight during the day and emit that energy back again as light once they're thrown into darkness. In most of these areas, those materials take the form of stones scattered across the ground, creating an effect which mirrors the stars scattered in the sky above. In some places where lines are needed, paint is used as well.



The parking lot has glow stones set throughout the pavement, as well as glow in the dark lines marking parking slots. The gravel pathways to and around the planetarium and the gravel of the courtyard sundial also have stone stones scattered throughout, easily marking the paths at night.




The lobby floor in an exposed aggregate concrete made with a mixture of regular and glow stones. All doorways and walls are also clearly marked with glow in the dark paint, in case of an emergency.




The outdoor observatory stairs are also set with glow stones, raised slightly higher than the concrete for traction. These stones are scattered throughout to form a starry look, but are also set in a dense line at the edges of the steps, to illuminate the stairwell and clearly define each step. The handrail is also painted to glow in the dark.
