Showing, “- Losing the Dark with a Brief Star Talk”

Starry skies are a vanishing treasure because light pollution is washing away our view of the cosmos. It not only threatens astronomy, it disrupts wildlife, and affects human health. The yellow glows over cities and towns – seen so clearly from space – are testament to the billions spent in wasted energy from
lighting up the sky.
Losing the Dark is a “public service announcement” planetarium show, a collaboration of Loch Ness Productions and the international Dark-Sky Association. It introduces and illustrates some of the issues regarding light pollution, and suggests three simple actions people can take to help mitigate it.

The show gives planetarium professionals a tool to help educate the public about the problems of light pollution. Planetariums are uniquely positioned to teach audiences way we can all work together to implement responsible use of lighting.
