有时我们会看到月球直接在我们太阳系的一颗行星前面移动，这被称为掩星。本月早些时候，这颗行星就是木星。这里捕捉到了木星从月球表面后面重新出现的那一刻。月亮在第三季度，在黑暗的新月出现的前两天。现在，我们的月球一直有一半被太阳照亮，但在其三分之一的时候，从地球上只能看到相对较少的一半。照片中，月球本身在美国加利福尼亚州著名的利克天文台后面，位于汉密尔顿山顶。巧合的是，里克发现了木星的一颗卫星：阿玛尔忒亚，这是伽利略观测后最后一颗被肉眼探测到的木星卫星。图集：2023年5月月球遮蔽木星：APOD值得注意的提交

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.
