National Park Foundation:

Depending on where you live in the world, viewing the night sky in its natural, unhindered state can be a rarity. Due to light pollution, fewer than 500 stars are viewable in urban settings, compared to the 15,000 stars apparent in some of the darkest skies.

National parks provide some of the darkest and clearest night skies across the country. And thatโ€™s why the National Park Foundation supports programs that help connect visitors with night sky viewing opportunities in some of these special places.

A grant from the National Park Foundation funded the startup of Mammoth Cave After Dark, a program aimed at showing visitors the night sky at Mammoth Cave National Park. Visitors who participated in Mammoth Cave After Dark enjoyed a guided hike, guided cave tour, dinner, and stargazing.
