The north pole of Saturn’s moon Enceladus is unexpectedly fascinating and complex. Previous to the latest flyby of the robotic Cassini spacecraft, the northern region was known mostly for its unusually high abundance of craters. Last week’s flyby, however, returned images of unprecedented detail, including the featured image showing the expected craters coupled with an unexpected and circuitous pattern of picturesque cracks and fractures. Broken terrain has been recorded at lower latitudes, with deep canyons dubbed Tiger Stripes near Enceladus’ South Pole. The fractures may further indicate global interplay between the surface and potential seas underneath, seas that future missions might target for signs of life. Retrospective: Today in APOD History

🌌 最新的研究顯示，土星的衛星恩克拉多斯（Enceladus）北極地區出乎意料地迷人而複雜！在機械人探測器卡西尼（Cassini）的最新飛掠之前，這個北部地區主要以其異常高的隕石坑數量而聞名。然而，最近的飛掠回傳了前所未有的細節影像，展示了除了預期的隕石坑之外，還有一條條意外而迂迴的裂縫與破碎地形。
之前在低緯度的地區已經記錄有破碎地形，尤其是南極附近的「老虎條紋」（Tiger Stripes）深谷。這些裂縫可能進一步顯示了地表與潛在的地下海洋之間的全球性相互作用，這些海洋將是未來探測任務尋找生命跡象的目標。
