Given some poetic license, there is now scientific evidence that hell has frozen over. To start, Greek mythology holds that Charon is the ferryman of the underworld. Next, recent analysis of data taken by the robotic New Horizons spacecraft that shot past Charon — the namesake that is the largest moon of Pluto — in July now indicates that the cause of the huge chasm that runs across the 1200-km moon was that a huge internal sea froze. And since water expands when it freezes, the already hardened outer crust could not contain it and cracked. To better picture the crack, a fanciful journey over some of Charon’s has been digitally created from collected images. The featured video starts by showing the Dark Polar Deposit (dubbed Mordor) near Charon’s north pole and then flies over the dwarf-planet-wide canyon. Last, the video shows a much-debated protuberance called Moated Mountain. Understanding the history of Pluto and Charon is helping humanity to better understand both the friendliest and more forbidding places in the early Solar System from which Earth formed and life somehow emerged.

🌌❄️ 近期嘅科研證據表明，地獄真的凍結咗！根據希臘神話，查朗（Charon）係冥界嘅渡船員。而最近新視野號（New Horizons）探測器於七月掠過查朗時，分析到嘅數據顯示，查朗這個冥王星最大嘅衛星上，貫穿佢嘅巨大裂谷系由於一個龐大嘅內部海洋凍結所造成嘅。水在凍結時會膨脹，已經硬化嘅外殼無法承受，最终裂開了。
如果想更好咁想像呢個裂口，我哋數碼化咗一次奇妙嘅旅程，從收集到嘅影像創建咗一個影片，首先展示咗查朗北極附近嘅黑暗極地沉積物（稱為莫多（Mordor）），然後飛越全衛星所覆蓋嘅峽谷，最後展示咗一個受到爭議嘅突出物——環山（Moated Mountain）。了解冥王星同查朗嘅歷史有助於人類更好咁理解早期太陽系中既友善地方同可怕地方，從而理解地球形成同生命出現嘅過程。
