How can curiosity about the universe lead to deeper insights into Earth’s climate, humanity’s future, and the interconnectedness of all existence?

Today’s guest is Suchitra Narayanan, an NSF Graduate Research Fellow at the Harvard-Smithsonian Center for Astrophysics and the Institute for Astronomy at the University of Hawai’i at Manoa. Suchitra’s groundbreaking research focuses on Organosulfur Chemistry in the Birthplaces of Planets, tackling the “missing sulfur problem” in space using ultra-high vacuum experiments, telescope observations, and theoretical models. Beyond her research, Suchitra is a passionate advocate for climate science and education, spearheading initiatives like the Climate Change Committee and authoring The Pale Blue Dot Blues, a compelling essay on the intersection of astrophysics and environmental advocacy.

In this episode, Suchitra shares her inspiring journey from growing up in Fremont to studying the origins of planets and molecules in space. We reflect on the moments that sparked her curiosity—like peering through a childhood telescope—and the importance of fostering awe in science education. Suchitra describes how her work in astrochemistry bridges the cosmic with the practical, exploring how studying distant worlds can deepen our understanding of Earth’s uniqueness and fragility.

We also dive into the existential questions posed by astronomy: How do we balance feelings of insignificance with a sense of responsibility for our planet? Suchitra shares her perspective on how studying the universe gives us the tools to inspire collective action against climate change, emphasizing that there is no “Planet B.” Through candid reflections on her academic journey, such as battling imposter syndrome and finding purpose, Suchitra shows how curiosity, wonder, and advocacy can coexist to drive meaningful change.

This episode is an invitation to look up at the stars and reflect on the preciousness of our own world—reminding us that understanding the unknown is key to protecting what we already have.
