About this episode
New research from ETH Zurich suggests that Earth formed almost entirely from inner solar system material. Isotopic evidence shows that less than 2% came from beyond Jupiter, challenging long-held theories about external contributions.
This implies that Jupiter acted as a barrier early on—meaning key ingredients like water may have originated locally, reshaping our understanding of planetary formation.
