The Search for Life in the Universe

Are we alone? It’s a question that has obsessed us for centuries, and now we have the technology to do more than wonder. Scientists on the hunt for distant planets and extraterrestrial intelligence explore faraway galaxies and barely visible realms. Nobel Laureate Sir Paul Nurse journeys to the brink of discovery with Jill Tarter, David Charbonneau, and Steven Squyres to contemplate what it would mean to have company in the cosmos.

The World Science Festival gathers great minds in science and the arts to produce live and digital content that allows a broad general audience to engage with scientific discoveries. Our mission is to cultivate a general public informed by science, inspired by its wonder, convinced of its value, and prepared to engage with its implications for the future.
