What could survive an impact so massive it should have shattered the entire world into pieces? Saturn's scarred survivor Tethys holds dark secrets - a massive crater that spans half its diameter, a colossal trench wrapping around its body, and a bizarre thermal anomaly that looks just like Pac-Man. In this video, we uncover the shocking secrets frozen in Tethys' icy shell and discover how this scarred world became one of the solar system's most remarkable survivors.
