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. ▀▀▀▀▀▀ 1:30 Discovery 2:19 The Ice World 4:19 Ithaca Chasma: The Great Crack 5:14 Bursting Open 8:12 Odysseus Crater 9:15 Healing Ancient Scars 12:09 The Pac-Man Phenomenon 13:15 Why Does Tethys Look Like Pac-Man? 15:58 The Survivor ▀▀▀▀▀▀ Astrum's newsletter has launched!
