JWST detects water vapor in a planet-forming disk
A team of researchers using the James Webb Space Telescope (or JWST) has made the first detection of water vapor in the inner region of the protoplanetary disc that is already forming worlds. Giulia Perotti and Thomas Henning from the Max Planck Institute for Astronomy in Germany join Planetary Radio to discuss their team's research on PDS 70 and what it can tell us about the formation of planets like Earth. The Planetary Society's most recent intern, Ariel Barreiro, reflects on her summer working with The Planetary Society, and Bruce Betts, our chief scientist, pops in for What's Up and a conversation about terminator zones.
