冥王星之夜
Pluto at Night
發表日期:2024-11-16
冥王星的夜面就在這朦朧的景象中。在這個令人驚歎的太空視角中,太陽在這個昏暗而遙遠的世界後面 49 億公里(近 4 . 5 光時)處。這是遙遠的 "新視野 "號於 2015 年 7 月拍攝到的,當時飛船距離冥王星約 2 . 1 萬公里,距離冥王星最近時約 19 分鐘。冥王星是柯伊伯帶的一個居民,它的輪廓引人注目,這幅影像還揭示了冥王星脆弱而又令人驚訝的複雜的朦朧大氣層。在畫面頂部附近,新月般的黃昏景觀包括現在正式被稱為斯普特尼克星的氮冰平原南部地區,以及諾爾蓋山崎嶇的水冰山脈。
原文:The night side of Pluto spans this shadowy scene. In the stunning spacebased perspective the Sun is 4.9 billion kilometers (almost 4.5 light-hours) behind the dim and distant world. It was captured by far flung New Horizons in July of 2015 when the spacecraft was at a range of some 21,000 kilometers from Pluto, about 19 minutes after its closest approach. A denizen of the Kuiper Belt in dramatic silhouette, the image also reveals Pluto's tenuous, surprisingly complex layers of hazy atmosphere. Near the top of the frame the crescent twilight landscape includes southern areas of nitrogen ice plains now formally known as Sputnik Planitia and rugged mountains of water-ice in the Norgay Montes.
