Join SETI Live host Moiya McTier with Néstor Espinoza (STScI) and Ana Glidden (MIT) for a deep dive into the latest JWST observations of TRAPPIST‑1 e, one of the most tantalizing Earth-sized planets in the habitable zone of a nearby star.

In this episode, we explore:

  • How JWST is peering into TRAPPIST-1 e’s atmosphere (or lack thereof).
  • Why the planet almost certainly doesn’t have a thick hydrogen envelope, ruling out a mini-Neptune-like world.
  • The emerging hints of a secondary, heavier atmosphere — or the possibility that it’s a bare rock.
  • The challenges posed by stellar activity and their implications for habitability.

Get ready for a conversation about exoplanet atmospheres, habitability, and the next steps in characterizing worlds beyond our Solar System.

Scientists are getting closer in their search for life beyond earth. But with limited federal funding for the search for extraterrestrial intelligence, supporters are the reason cutting-edge scientists can keep their eyes on the sky.
