Queen Mab and the Dust Engine: A Tiny Moon That Powers Uranus’ Rings

About this episode

A humbling deep dive into MAB (formerly S2003-U1), the faint Uranian moon that evades easy measurement and even Voyager 2’s flyby. We trace its Hubble discovery in 2003, the mystery of its size, and how a chaotic, Goldilocks-sized moon acts as a self-sustaining dust factory that feeds Uranus’ ring system. This episode explores how a small world can shape a giant structure, challenging our maps of the solar system.
