Tyler Nordgren captured this lunar eclipse sequence from his campsite in Grand Teton National Park on the night of August 29, 2007. He took an exposure of the moon every 10 minutes until it disappeared and the sun lit up the mountains with alpenglow. Credit: Tyler Nordgren

Astronomer and physics professor Tyler Nordgren took a journey across the American landscape, exploring the connections between the parks and the wonders of the night sky.  He visited twelve parks in twelve months, from the icy grandeur of Denali National Park in Alaska to the red rocks and steep-walled canyons of Bryce Canyon National Park in Utah.  As he met with park experts and visitors, he examined the themes that link the parks to other landscapes in the solar system, and wrote about what he discovered here on The Planetary Society's website.  Through it all, he enjoyed the uniquely dark skies that grace most national parks, a resource that is quickly vanishing from the rest of the country.
