Three children of the Sun rise in the east in this peaceful dawn skyview recorded December 7th near Bolu, Turkey. Inner planet Mercury, fresh from its second transit of the 21st century, stands highest in the bright sky at the top right. Gas giant Jupiter lies below the cloud bank near picture center. A newsworthy Mars is also visible, right of Jupiter and just above the dark cloud bank. On Sunday, these planets will form a much tighter grouping before sunrise, while in the coming days the western sky after sunset will be ruled by brilliant planet Venus, also known as the evening star.

這幅12月7日在土耳其Bolu附近拍攝的靜謐黎明天空影像裡，三顆太陽的子女從東方昇起。水星這顆最內圍的行星，高懸在漸亮天空的右上角落，最近剛經歷它21世紀第二次的淩日事件。木星這顆氣態巨行星則在影像中央層積雲的下方。而常上新聞的火星，則在木星的右上方稍高於層積雲的位置。在星期天的日出之前，這三顆行星將聚得更緊密。而在接下來的這段日子裡，明亮的金星將在日落後的西方天空大放異彩，成為名副其實的"黃昏星"。
