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):

Guided by host Dave Schlom, discussions commonly bridge Earth and space, connecting big-picture questions about humanity’s place in the universe with grounded, place-based science.
A major thread is space science and exploration. Listeners can expect accessible explanations of the physics behind spaceflight, the scientific goals of modern lunar missions, and historical context for key milestones in human space travel. Astronomy topics also appear, including explorations of small bodies in the solar system and how researchers study them.
Another strong focus is environmental and ecological science, often centered on the U.S. West Coast and the Pacific Northwest. The podcast returns frequently to rivers, deltas, coastal waters, and marine ecosystems, examining watershed history, biodiversity, and conservation work. Field research and wildlife topics are also prominent, including studies of seabirds and Antarctic ecosystems, along with perspectives from conservation biologists and nature photographers.
The show also explores risk, hazards, and resilience through scientific lenses—such as tectonics, earthquakes and tsunamis, wildfire ecology and the use of “good fire,” and analyses of high-profile engineering disasters. Interdisciplinary themes appear as well, including how philosophy can inform physics and how teaching approaches shape learning in challenging scientific subjects. Occasionally, conversations extend into science-adjacent cultural and historical territory, such as the history of valuable materials.
