Exploring the questions surrounding UAPs and the search for extraterrestrial life
22/05/2026
Unexplained sightings have appeared in our skies for years, and now the U.S. government has started releasing declassified files about what we used to call UFOs. What explains these phenomena, and what do we know about life beyond Earth? Horizons moderator William Brangham explores what we do know, and what we don't, with Leslie Kean and Garrett Graff, two authors who've studied this topic deeply.

Stephanie Sy reports on an effort to boost the integrity of carbon markets and open them up to small landowners. It's part of our series, Tipping Point.
