[漢羅] Kah 月掩木星 排做一逝 ê 天文台

有當時仔咱會看著 月娘 ùi 咱 太陽系 內底其中一粒行星面頭前趨過，這就叫做掩星。 發生 tī 這個月初 ê 掩星現象，閘 ê 就是木星。 這張相片 就是 木星 去予月娘閘牢了後，重新 ùi 月娘 後壁 出現 ê 時陣翕--ê。 這陣月娘 ê 月相已經來到 下月眉，閣 2 工就欲 初一 矣。 咱 ê 月娘 總是有一半去予日頭照著，毋過等到下月眉 ê 時陣，咱 tī 地球 看，嘛干焦看會著彼半爿月娘 ê 一部份爾爾。 Tī 這張相片內底，月娘就排 tī 美國 加州 Hamilton 山頂 彼个有名 ê Lick 天文台 後壁。 是講誠拄好，Lick 天文台 是發現木星 ê 衛星 木衛五 Amalthea ê 所在，是 Galileo 觀測著 木星四大衛星了後，上尾一粒用目睭揣著 ê 衛星。

[English] Observatory Aligned with Moon Occulting Jupiter

Sometimes we witness the Moon moving directly in front of -- called occulting -- one of the planets in our Solar System. Earlier this month that planet was Jupiter. Captured here was the moment when Jupiter re-appeared from behind the surface of our Moon. The Moon was in its third quarter, two days before the dark New Moon. Now, our Moon is continuously half lit by the Sun, but when in its third quarter, relatively little of that half can be seen from the Earth. Pictured, the Moon itself was aligned behind the famous Lick Observatory in California, USA, on the summit of Mount Hamilton. Coincidentally, Lick enabled the discovery of a moon of Jupiter: Amalthea, the last visually detected moon of Jupiter after Galileo's observations.
