Tyler Nordgren

    Tyler Nordgren, a professor of physics and astronomy, confronts the issue of light pollution and its impact on our perception of the universe. His work explores how the spread of artificial light diminishes the observable night sky, depriving many of a connection to the cosmos. Through his award-winning photography and educational efforts within national parks, Nordgren advocates for the preservation of dark skies. He bridges astronomy with art, history, and conservation, emphasizing that the wonders of the night sky are an integral part of our natural heritage.

    • 2010

      In Stars Above, Earth Below, Tyler Nordgren examines a range of astronomical topics and makes the connection between them and the landscapes, processes, and cultures which can be seen and experienced within specific U.S. National Parks. For each park and topic the story unfolds in three steps: what does the reader see for him - or herself? What is the scientific cause or explanation of what is seen? And finally, what is the big picture about ourselves, our world, and our Universe? The author takes us the length and breadth of the U.S., from the coast of Maine to the Yellowstone volcano, from the depths of the Grand Canyon to the heights of the Rocky Mountains, exploring the natural links between the features of the parks and those of our Universe.
