[漢羅] 銀河極光花

咱的銀河就親像是天頂這蕊花的花柄，佇天頂開出這蕊極光花。 無閣，就算 伊佇天頂看起來是按呢，實際上毋是按呢生！ 倒爿是咱銀河 的 中央盤，ùi 地平線 湠 tùi 夜空的中央。 正爿是 長株圓形的極光，嘛湠 tùi 夜空的中央。伊主要發出的 青光是 ùi 酸素來的。 這兩項實際上並無相連，因為 極光 是離咱足近的。 就算是 較懸的紅色極光，嘛才佇 地球大氣層 1000 公里 懸的所在爾爾。 佮極光比起來，銀河 內底的恆星佮星雲，平均距離嘛愛 1000 光年遠，是極光的 10 萬億 倍遐爾遠。 這幅圖 是 10 月初佇 瑞典 北方 Abisko 一个無蓋大的湖翕的。 咱的 太陽磁場 11 年一个週期，最近伊變甲愈來愈強，地球南北極的極光 嘛 變甲 愈來愈濟。

[English] Milky Way Auroral Flower

Could the stem of our Milky Way bloom into an auroral flower? No, not really, even though it may appear that way in today’s featured all-sky image. On the left, the central plane of our home galaxy extends from the horizon past the middle of the sky. On the right, an auroral oval also extends from the sky's center -- but is dominated by bright green-glowing oxygen. The two are not physically connected, because the aurora is relatively nearby, with the higher red parts occurring in Earth's atmosphere only about 1000 kilometers high. In contrast, an average distance to the stars and nebulas we see in the Milky Way more like 1000 light-years away - 10 trillion times further. The featured image composite was taken in early October across a small lake in Abisko, northern Sweden. As our Sun's magnetic field evolves into the active part of its 11-year cycle, auroras near both of Earth's poles are sure to become more frequent.
