Welcome to this special crossover episode from our other show, Going Off World.

In this episode, the hunt for alien life isn’t a sci-fi dream. It’s a patient, high-stakes investigation unfolding across labs, observatories, and space missions—and Sarah Seager is charting the course. We sit down with the MIT exoplanet pioneer to unpack how a field once defined by four puzzling worlds grew into a catalog of thousands, each challenging our assumptions about what planets can be and where life might take hold.

We trace Dr Sarah Seager’s path from early skepticism about hot Jupiters to leading-edge missions seeking signs of life in exoplanet atmospheres and even the acid clouds of Venus. The conversation blends technology, theory, and personal resilience to map the long road to finding another Earth.

If you care about exoplanets, biosignatures, Venus, and the future of discovery, this conversation is a guided tour of what it will take to spot another Earth and how that finding could reshape our place in the cosmos. If you enjoyed this episode, follow the show, share it with a friend who loves space, and leave a review to help more curious minds find us.
