Extended excerpt from the documentary The City Dark.
When filmmaker and amateur astronomer Ian Cheney moves into his apartment in New York, he climbs atop his Brooklyn rooftop to survey the night sky. But bathed in its glow of orange streetlights, the City that Never Sleeps only has five stars to see. What begins as a disappointing autumn evening becomes a journey to answer a simple question: do we need the stars? In showing how artificial light affects our health and planet, The City Dark will blend cutting edge-science with real human stories, all rendered in beautiful HD cinematography. While broadening our understanding of the environmental implications of artificial light, The City Dark will feature an unprecedented portrait of the sky above our heads.
