On June 30 Venus and Jupiter were actually far apart, but both appeared close in western skies at dusk. Near the culmination of this year’s gorgeous conjunction, the two bright evening planets are captured in the same telescopic field of view in this sharp digital stack of images taken after sunset from Poznań in west-central Poland. In fact, banded gas giant Jupiter was about 910 million kilometers from Poland. That’s over 11 times farther than crescent Venus, only 78 million kilometers distant at the time. But since the diameter of giant planet Jupiter is over 11 times larger than Venus both planets show about the same angular size. Of course, 16th century Polish astronomer Nicolaus Copernicus would also have enjoyed the simultaneous telescopic view including Jupiter’s four Galilean moons and a crescent Venus. Observations of Jupiter’s moons and Venus’ crescent phase were evidence for the Copernican or heliocentric model of the solar system.

在6月30日，金星（Venus）和木星（Jupiter）實際上相距遙遠，但在黃昏時分，兩顆亮眼的行星卻在西方天空中顯得非常接近。在今年迷人的合相的高潮時刻，這兩顆明亮的黃昏行星在西中歐波茲南（Poznań）的晚霞下於同一望遠鏡視野內被清晰捕捉到。事實上，帶有帶狀雲的氣體巨行星木星當時距離波茲南大約910萬公里，比金星的78萬公里遠了超過11倍。不過，由於巨行星木星的直徑是金星的11倍以上，兩顆行星在視角上看起來幾乎一樣大。 當然，16世紀的波蘭天文學家尼古拉斯·哥白尼（Nicolaus Copernicus）也一定會欣賞這個同時的望遠鏡視圖，包含木星的四個伽利略衛星和一個彎曲的金星。觀察木星的衛星和金星的螺旋相位，為哥白尼的日心說模型提供了證據。
