土星現在在午夜前升起在地球的天空中。 7 月 24 日,這顆肉眼可見的行星在天空中與一輪殘月近距離相合。但在地球上的一些地方,這顆環狀氣體巨行星卻被掩蔽了,在亞洲和非洲部分地區的天空中,它在月球背後消失了大約一個小時。由於月球和明亮的行星在黃道面附近的天空中游蕩,這種掩星事件並不少見,但也可能非常引人注目。在這幅從中國江蘇南京拍攝的望遠鏡檢視中,土星在消失在月盤後面的前一刻被捕捉到。這張快照給人一種錯覺,土星就懸掛在格盧什科隕石坑上方,這是一個直徑 43 公里、年輕的射線隕石坑,靠近月球西部邊緣。當然,月球距離土星有 40 萬公里,而土星距離月球有 14 億公里。
原文:Saturn now rises before midnight in planet Earth's sky. On July 24, the naked-eye planet was in close conjunction, close on the sky, to a waning gibbous Moon. But from some locations on planet Earth the ringed gas giant was occulted, disappearing behind the Moon for about an hour from skies over parts of Asia and Africa. Because the Moon and bright planets wander through the sky near the ecliptic plane, such occultation events are not uncommon, but they can be dramatic. In this telescopic view from Nanjing, Jiangsu, China, Saturn is caught moments before its disappearance behind the lunar disk. The snapshot gives the illusion that Saturn hangs just above Glushko crater, a 43 kilometer diameter, young, ray crater near the Moon's western edge. Of course, the Moon is 400 thousand kilometers away, compared to Saturn's distance of 1.4 billion kilometers.
