Pluto surface is strange. As the robotic New Horizons barrels toward its closest approach to Pluto and its moons tomorrow, images already coming back show Pluto’s surface to be curiouser and curiouser. The featured image, taken two days ago, shows the side of Pluto that always faces Pluto’s largest moon Charon. Particularly noteworthy is the dark belt near the bottom that circles Pluto’s equator. It is currently unclear whether regions in this dark belt are mountainous or flat, why boundaries are so sharply defined, and why the light regions seem to be nearly evenly spaced. As New Horizons will be flying past the other side of Pluto, this should be the best image of this distant landscape that humanity sees for a long time. Assuming the robotic spacecraft operates as hoped, images taken of the other side of Pluto, taken near closest approach, will be about 300 times more detailed. Latest: Best image yet of Charon.

🌌🚀【新晉天文探索】普洛的表面真是奇妙無比!隨著機械探測器新視野號(New Horizons)正快速接近普洛(Pluto)及其衛星,最新傳回的影像顯示出普洛表面愈發令人著迷。這幅圖片是兩天前拍攝的,展示了普洛永遠面向最大衛星卡戎(Charon)的那一面。
🌓 其中,最引人注目的是位於底部的黑帶,這條黑帶圍繞在普洛的赤道附近。現時仍不清楚這些黑帶中的區域是山地還是平坦,邊界何以如此分明,以及為何淺色區域看起來幾乎均勻分佈。作為新視野號將飛越普洛的另一側,這將是人類在相當長一段時間內看到的最清晰的景觀影像。
📷 如果新視野號運行如預期,在最近的接近過程中拍攝的普洛另一側影像將會有約300倍的細節。
