In the latest episode of “Looking Up,” host Dean Regas converses with Stephen Hummel, the Dark Skies Initiative coordinator from the University of Texas at Austin and McDonald Observatory. They discuss the growing problem of light pollution, which has significantly reduced the visibility of stars for over 80% of Americans, especially children. Hummel emphasizes the cultural and health impacts of losing dark skies, including sleep disorders and ecological disruptions. Despite the challenges posed by urban expansion, the episode highlights potential solutions and encourages listeners to support dark sky preservation efforts. Listeners are invited to share their thoughts via email or social media, and to explore opportunities to experience truly dark skies through summer star parties at national parks.
