A canopy of stars in the night sky is more than breathtaking. Starlight is also an important tool that astronomers use to study our universe. But the growth of artificial light and light pollution are creating dramatic changes to the nighttime environment. Let your eyes adjust to the dark as we travel to a dark sky reserve to gaze upon an increasingly rare view of the Milky Way and explore what we lose when darkness disappears.

Guests:

Kim Arcand – Visualization scientist & emerging tech lead, NASA's Chandra X-ray Observatory and author of “Light: The Visible Spectrum and Beyond".

Don Jolley – Teacher of Math and Sciences at the Bolinas School in Marin, California who has been leading dark sky tours for three decades.

Christopher Kyba – Interdisciplinary Geographic Information Sciences Research Fellow at Ruhr University Bochum.
