Blue Dot, named after Carl Sagan's famous speech about our place in the universe, features interviews with guests from all over the regional, national and worldwide scientific communities. Host Dave Schlom leads discussions about the issues science is helping us address with experts who shed light on climate change, space exploration, astronomy, technology and much more. Dave asks us to remember: from deep space, we all live on a pale, blue dot.Themes and summary (AI-generated based on podcaster-provided show and episode descriptions):
➤ Science interviews • Climate and ecosystems • California landscapes, Delta, Salish Sea • Wildfire “good fire” and regenerative agriculture • Earthquake/tsunami hazards • Space exploration, NASA history • Astronomy: comets, black holes, JWST • SETI, Fermi Paradox • Titan submersible disasterThis podcast presents interview-driven conversations with scientists, engineers, authors, and other experts about how science helps explain the universe and address real-world challenges on Earth. Guided by Carl Sagan’s “pale blue dot” perspective, the show ranges from space and astronomy to environmental science, geology, and technology, often connecting big-picture questions to specific places and current events.
Across these episodes, listeners can expect explorations of astronomy and space exploration, including discussions of comets, black holes and unusual stellar systems, the search for extraterrestrial intelligence, and the history and legacy of human spaceflight and major space missions. The podcast also examines Earth systems and hazards, with attention to tectonics, earthquakes, tsunamis, and the scientific understanding of disasters and high-risk engineering failures.
A strong theme is the ecology and stewardship of landscapes and waterways, particularly in the U.S. West. Topics include marine and coastal research in the Pacific Northwest, the complexity and vulnerability of major river-delta ecosystems, and the role of fire in ecosystem management and community resilience. The show also touches on regenerative agriculture and how land-use practices intersect with environmental health.
In addition to science reporting, the podcast sometimes brings in cultural and historical perspectives—such as prehistoric sites and how science advisers contribute to popular media—to show how scientific ideas circulate beyond the lab. Overall, the content blends accessible explanations with expert insight across astronomy, environmental change, natural history, and applied science.
