[漢羅] 土星 ê 一季

有環 ê 土星 會 tī 2023 年 8 月 27 行到「土星衝」ê 位置，就是 tī 地球天頂看著太陽 kah 土星 差 180 度。 這粒離太陽第 6 遠 ê 行星 tī 這工 會上光，嘛是咱上好觀測 ê 角度。 毋過咱猶是無法度直接用目睭看著伊美麗 ê 環系統。 是講，這个系列相片是 ùi 內行星 地球 ê 角度來翕土星 kah 土星環。 1 年翕 1 張，攏總有 6 張望遠鏡影像。 這粒氣態巨行星 ê 環平面 tī 2018 年 ê 時陣 是正面向咱，到 2023 年 ê 時陣 已經是側面向咱矣（ùi 頂懸到下跤）。 土星 ê 北半球 嘛 ùi 熱天 行到 秋分。 Tī 這組清楚 ê 行星肖像內底，土星北半球 ê 六角雲 kah 大型 風暴 系統 嘛 tī 2018 年 ê 影像內底看甲足清楚--ê。 Tī 2023 年 ê 時陣，冰衛星 土衛三 Tethys 發生 凌土現象，就是 ùi 土星面頭前行過，伊 ê 烏影就投影 tī 土星南半球 ê 雲帶。 土星南極 是 冷閣藍，這馬才拄欲結束伊 10 年長 ê 寒天 kah 暗暝。

[English] A Season of Saturn

Ringed planet Saturn will be at its 2023 opposition, opposite the Sun in Earth's skies, on August 27. While that puts the sixth planet from the Sun at its brightest and well-placed for viewing, its beautiful ring system isn't visible to the unaided eye. Still, this sequence of six telescopic images taken a year apart follows both Saturn and rings as seen from inner planet Earth. The gas giant's ring plane tilts from most open in 2018 to approaching edge-on in 2023 (top to bottom). That's summer to nearly the autumn equinox for Saturn's northern hemisphere. In the sharp planetary portraits Saturn's northern hexagon and a large storm system are clearly visible in 2018. In 2023 ice moon Tethys is transiting, casting its shadow across southern hemisphere cloud bands while Saturn's cold blue south pole is emerging from almost a decade of winter darkness.
