[漢羅] 土星光下 ê 土衛一 Mimas

有半爿面一直面對土星 ê 土衛一 Mimas，to̍h ùi 烏影彼爿 kā 咱睨。 伊 to̍h tī 差不多全烏 ê 世界內底，產生這个 戲劇性、反射太陽光 ê 月眉形影。 這个拼鬥影像是 tī 2017 年 1 月 30，Cassini 太空船上尾一改 倚近伊 ê 時陣翕 ê。 Cassini ê kha-mé-lah 囥 tī 面對太陽 ê 方向，離 Mimas 干焦 45000 公里近 ê 所在。 這是其中一个上懸解析度 ê 影像，是一个冷冰冰、隕石坑滿滿是、直徑 400 公里闊 ê 衛星。 有半爿一直面對土星，是因為伊 kah 土星同步自轉 ê 結果。 有一个強化影像會當看著這半爿，是土星反射太陽 ê 光去照著 Mimas ê 影像。 為著欲看著這个影像，你會當 tī 這張影像面頂徙動你 ê 滑鼠（抑是 點這个連結）。 其他 Mimas ê Cassini 影像，閣有 tī 這粒細粒衛星面頂較大 ê、不祥 ê Herschel 隕石坑。

[English] Mimas in Saturnlight

Peering from the shadows, the Saturn-facing hemisphere of Mimas lies in near darkness alongside a dramatic sunlit crescent. The mosaic was captured near the Cassini spacecraft's final close approach on January 30, 2017. Cassini's camera was pointed in a nearly sunward direction only 45,000 kilometers from Mimas. The result is one of the highest resolution views of the icy, crater-pocked, 400 kilometer diameter moon. An enhanced version better reveals the Saturn-facing hemisphere of the synchronously rotating moon lit by sunlight reflected from Saturn itself. To see it, slide your cursor over the image (or follow this link). Other Cassini images of Mimas include the small moon's large and ominous Herschel Crater.
