What do the sharpest views ever of Pluto show? As the robotic New Horizons spacecraft moves into the outer Solar System, it is now sending back some of the highest resolution images from its historic encounter with Pluto in July. Featured here is one recently-received, high-resolution image. On the left is al-Idrisi Montes, mountainous highlands thought composed primarily of blocks of water ice. A sharp transitional shoreline leads to the ice plains, on the right, that compose part of the heart-shaped feature known as Sputnik Planum, which contains ices including solid nitrogen. Why the plains are textured with ice pits and segmented is currently unknown. The image was taken about 15 minutes before closest approach and shows an area about 30 kilometers across. The New Horizons spacecraft is next scheduled to fly past Kuiper Belt object 2014 MU 69 on New Year’s Day 2019. AAS Members: How does APOD help you?

🪐✨ 探索冥王星的尖端視野！新視野(New Horizons)太空船於七月的歷史性接觸後，送回了一些最高解析度的圖片。最近收到的一張高解析度圖像顯示了這個令人驚嘆的景觀！左側為阿爾-伊德里西山脈(al-Idrisi Montes)，這片高地主要由水冰塊組成。清晰的過渡海岸線通向右側的冰平原，這些平原是心形特徵稱為斯普特尼克平原(Sputnik Planum)的一部分，包含固體氮等冰物質。這些平原上有著冰坑和分段的紋理，目前尚不清楚其原因。這張圖片是在距離最近接觸約15分鐘的時候拍攝的，涵蓋了約30公里的區域。新視野太空船將於2019年元旦再度飛越柯伊伯帶物體2014 MU 69。
