Traveling Pop-Up Display: IDA has created six traveling pop-up displays for free. They’re easy to assemble and come in six different themes: “Heritage of Our Night Sky,” “Light Pollution and Wildlife,” “Artificial Light at Night and Human Health,” “Lighting and Energy Waste,” “Lighting and Safety,” and “Solutions.” We ship our ever-popular pop-up displays to you for free and only ask that you pay the return postage when shipping them back. To request our traveling pop-up displays please contact Susan Ciarniello at or 520-293-3198.

IDA also provides high-resolution PDFs of the displays to download for free, so you can have them printed as displays or posters.

Astronomy Handouts: These handouts present information on dominant constellations at various times in the year. They detail how to find these constellations, astrological features and deep space objects in each, and associated myths.


IDA’s “Losing the Dark” is a free informative six-minute introduction to light pollution that can either be streamed online or downloaded onto your computer.
