The night we share

Make room for darkness.

Small choices about where and when we use light help preserve a view of the night.

A dark sky is something to care for. This lesson adapts the baseline Night Sky classroom's stewardship theme, with new symbolic drawings. It is a reading activity, not a sky chart or a forecast.

Unshielded lightSymbolic lighting illustration. Decorative stars have no measured positions or brightness; not a prediction of visibility.Light spills beyond the task

01 / Where it goes

Notice light that spills upward.

Light sent into the sky does not illuminate the task on the ground. Consider what needs lighting and where the light actually goes.

Downward-directed lightSymbolic lighting illustration. Decorative stars have no measured positions or brightness; not a prediction of visibility.Light directed to the task

02 / Aim it

Direct useful light downward.

The National Park Service describes downward-directed fixtures as one way to reduce light pollution. The cone here is symbolic, not a measurement of a lamp.

A light switched offSymbolic lighting illustration. Decorative stars have no measured positions or brightness; not a prediction of visibility.Light off when unneeded

03 / When it is needed

Use light when the task needs it.

Controls that switch lights on when needed can reduce unnecessary illumination. Keep enough light for the actual task; this is not advice to walk in darkness.

Original symbolic BCC lighting diagrams. Stars are decorative marks, not catalogue positions, measured brightness or predicted visibility. No HYG data, source photography or astronomy calculation is bundled.

A saved lesson is not tonight's sky

Clouds, Moon light and other conditions affect what you can see. This file contains no observing forecast, current park programs or access report. Use the clearly marked online NPS source for further reading.

Try a light audit

From a safe place, sketch one light you already know. Mark what it is intended to illuminate, where it spills, and when it is useful. Describe a question or possible improvement without claiming a measured benefit.

Try it yourself

Choose the useful change.

For a light left on after its task is finished, which change most directly addresses when it is needed?

Read the choices and explanations in the answer notes below.

Answer notes · also included in print
  1. Make the lamp brighter all night.
    That changes brightness, but does not address whether the task still needs light.
  2. Add more stars to the drawing.
    A drawing can change while the real lighting stays the same. It is not evidence of darker skies.
  3. Use a suitable control to turn it off when unneeded.
    Yes. This addresses timing. Suitable controls depend on the task and its safety requirements.
