西西里灯塔上空的天体大近合

Explanation: Don’t miss the coming great conjunction. In just under two weeks, the two largest planets in our Solar System will angularly pass so close together in Earth’s sky that the Moon would easily be able to cover them both simultaneously. This pending planetary passage — on December 21 — will be the closest since 1623. Jupiter and Saturn will remain noticeably bright and can already be seen together toward the southwest just after sunset. Soon after dusk is the best time to see them — because they set below the horizon soon after. In mid-November, the Jovian giants were imaged together here about three degrees apart — and slowly closing. The featured image, including a crescent moon, captured the dynamic duo beyond the Cape Murro di Porco Lighthouse in Syracuse, Sicily, Italy.

说明: 别错过一场即将来临的天体大近合。再过不到2星期，我们太阳系最大的2颗行星，在地球天空的张角间距，将小到一轮明月就能同时盖住两者。这个将出现在12月21日的行星近合，是自1623年以来最接近的一次。在这段日子刚日落之后，木星与土星会是西南方很明亮且相去不远的结伴天体。不过要看得快，因为日落后不久它们就会隐没西沉。在摄于11中旬的这幅主题影像里，这二颗类木行星相距约3度，而且逐渐往对方靠近。影像中，除了蛾眉月之外，还可见到位在意大利西西里岛西勒鸠斯Cape Murro di Porco灯塔 后方的这对巨行星。
