Featuring Dan Tell, Morrison Planetarium

Do alien worlds hold the answers to humanity’s future? Can we use the discoveries from astronomy and modern space science to address the climate crisis here on Earth? Synthesizing the last 15 years of research lectures and science visualization at the California Academy of Sciences, this immersive talk was originally presented at last fall’s Ars Electronica Festival in Linz, Austria. We will explore what we know about potentially habitable worlds, but also how modern space-based observations of our home planet can guide us toward a regenerative future.
