[漢羅] Akatsuki 號太空船 翕--ê 金星 ê 紫外光影像

是按怎金星 kah 地球遮爾無仝？ 為著欲揣出這个答案，日本 進前發射 ê 機器人太空船 Akatsuki 號 tī 2015 年底 飛入去金星軌道。 伊進前有 5 年 ê 時間是無照計畫 tī 內太陽系 內底賴賴趖。 就算 Akatsuki ê 性命長度已經超過本底 ê 計畫，毋過因為太空船 kah 儀器攏運作甲好勢好勢，所以大部份 ê 任務總算是 有繼續完成。 Akatsuki ê 儀器嘛叫做 金星 氣候軌道衛星，是 leh 調查咱 ê 姊妹仔行星 金星 頂懸 一寡咱猶無了解 ê 代誌，包括火山是毋是猶活跳跳、實密 ê 大氣內底是毋是會產生爍爁、風速是按怎會超過火星自轉 ê 速度 遐爾濟。 這張影像 是 Akatsuki ê UVI kha-mé-lah 翕--ê。 咱看會著日時彼爿 ê 金星 有 行星尺度 ê V-形雲。 影像內底有三款無仝色 ê 紫外光，閣有淺藍色 ê 二酸化硫，伊 ê 量是有變較少。 分析 Akatsuki ê 影像 kah 資料了後，除了 一寡發現以外，閣知影講金星有親像 地球高速氣流 仝款 ê 赤道噴流。

[English] Venus in Ultraviolet from Akatsuki

Why is Venus so different from Earth? To help find out, Japan launched the robotic Akatsuki spacecraft which entered orbit around Venus late in 2015 after an unplanned five-year adventure around the inner Solar System. Even though Akatsuki was past its original planned lifetime, the spacecraft and instruments were operating so well that much of its original mission was reinstated. Also known as the Venus Climate Orbiter, Akatsuki's instruments investigated unknowns about Earth's sister planet, including whether volcanoes are still active, whether lightning occurs in the dense atmosphere, and why wind speeds greatly exceed the planet's rotation speed. In the featured image taken by Akatsuki's UVI camera, the day-side of Venus is seen shown with planet-scale V-shaped cloud pattern. The image displays three ultraviolet colors and indicates a dip in the relative abundance of sulfur dioxide shown in faint blue. Analyses of Akatsuki images and data has shown, among other discoveries, that Venus has equatorial jet similar to Earth's jet stream.
