Hal Levison explains how Jupiter’s Trojan asteroids could help distinguish competing accounts of Solar System evolution. The discussion compares scenarios in which giant planets formed near their present orbits with models involving substantial migration from a more compact configuration. It considers why the Lucy spacecraft’s observations can test these ideas and how discoveries of other planetary systems sharpen the questions.

Eirik Newth discusses the history of space exploration, from human missions to robotic exploration of the Solar System. Conversation in Norwegian.
