Is Tau Ceti Our Project Hail Mary?

Eleven point nine light-years away, in the constellation of a mythological sea monster, sits a star that astronomers, SETI researchers, and science fiction writers have been collectively obsessed with since 1960. 🎧 Love the show?

Almost certainly. We explore the full and rather remarkable story of this ancient star, from Johann Bayer's 1603 star atlas and Frank Drake's original SETI search, through decades of planet hunting, a debris disk of genuinely alarming proportions, and the latest findings from the ESPRESSO spectrograph, which has made everything considerably more complicated. We also ask whether Tau Ceti represents a genuine opportunity for life beyond our Solar System — and why, despite everything, it refuses to stop being interesting. Plus: Ryan Gosling, the Kobayashi Maru, and the nine-billion-year question the universe is still sitting on.
