Caption: This breathtaking photograph was captured on 17 June 2023, near Keetmanshoop, Namibia, with a smartphone. Dominating the night sky, the majestic arc of the Milky Way creates a celestial bridge across the heavens. The image captures a range of notable astronomical objects: the Large and Small Magellanic Clouds, seen towards the bottom of the image and appearing as fuzzy clouds; Antares, seen towards the top left of the image; and the coalsack nebula (referred to by various names by Indigenous cultures around the world), seen vertically above the Large Magellanic Cloud. Silhouetted against this astral backdrop, the trees — which are actually succulent aloe plants native to southern Africa — add a touch of Earth's unique beauty. Historically, these plants were known as ‘quiver trees’ because groups of local Indigenous people would use their hollowed branches to hold darts. The serene Namibian landscape, combined with the brilliance of the southern hemisphere's stars, offers a glimpse into the majesty of our Universe.

Caption: 2023 年 6 月，在纳米比亚，H.E.S.S 天文台的天空一片漆黑，组成银河系的恒星似乎数不胜数，让人难以在这张用智能手机拍摄的照片上分辨星座。在照片左下方的塔附近，可见半人马座阿尔法星和贝塔星。在照片左侧的 H.E.S.S 望远镜右上方，可见一颗橙色恒星——心宿二，位于天蝎座心脏的一颗红巨星。

Caption: 这段延时摄影记录了2020年7月拍摄的三帧画面中标志性的北斗七星的轨迹。影像在意大利的三个地点拍摄：拉瓦雷多三峰（Tre Cime di Lavaredo）奥隆佐迪卡多雷、里特山（Monte Rite）奇比亚纳迪卡多雷，以及拉佐牧场（Casera Razzo）维戈迪卡多雷。这场视觉奥德赛展示了北斗七星的迷人轨迹，并在夜空中绘制出天体画卷。它不仅描绘了这个著名星群的轨迹，还捕捉到2020年7月照亮天空的罕见新智彗星 C/2020 F3 这一非凡的天文事件，为我们的夜空增添了光彩。

Caption: This video shows the Milky Way’s sprawling brilliance across the celestial expanse. Among the stars’ grand theatre, the Southern Cross constellation claims its place in the scene, distinguished by its distinctive cross shape as seen in the top of this video and slightly to the right just over the Milky Way, slowly disappearing as the video progresses. This celestial marker, a prominent feature in the southern hemisphere, holds cultural and navigational significance, having served as a navigational guidepost for centuries. Accompanying the Milky Way’s grandeur are the two Magellanic clouds, celestial companions seen dancing in the distant sky. The Carina Nebula adds its ethereal glow to the cosmic panorama, painting a radiant hue against the darkness. In the midst of this celestial ballet, a gentle green hue envelops the atmosphere, a phenomenon known as airglow, adding a touch of subtle luminescence to the night sky. The terrestrial also makes an appearance, with planes flying overhead and vehicles driving between observatory buildings. This time-lapse, taken from the La Silla Observatory in Chile, is a window to the captivating dance of stars, offering a glimpse into the awe-inspiring beauty of our galaxy and the celestial landmarks that grace the southern sky.
