Caption: 這張NASA“好奇號”火星車的自拍照展示了它在夏普山下的“鹿皮”岩石目標區域進行鑽探的場景。該照片由“好奇號”上的火星手持透鏡成像儀（MAHLI）於2015年8月5日拍攝，由多張組件圖像合成，拍攝時間為“好奇號”在火星任務中的第1065個火星日。

Caption: 這張由美國宇航局火星勘測軌道飛行器於 1999 年拍攝的火星圖像顯示了火星乾燥的表面。這張照片展示了火星上最壯觀的地質區域。除了深邃的馬林里斯谷之外，我們還看到了四座火山。其中三座形成了塔西斯山脊，而奧林帕斯火山則是我們迄今為止在太陽系中發現的最大的火山。冰雲覆蓋了火星表面的部分區域。

Caption: Honourable mention in the 2022 IAU OAE Astrophotography Contest, category Still images of celestial patterns: Equatorial Milky Way   Taken in Bromo-Tengger-Semeru National Park, Java Island, Indonesia, in March 2016, this image captures regions of the southern Milky Way and, at its left edge, the two planets Mars and Saturn. Mars appears orange and is similar in colour to the star Antares, whose Greek name — anti Ares — references this. Saturn is a little bit fainter than Mars, but clearly visible among the stars of Ophiuchus, above the Pipe Nebula and forming an isosceles triangle with Mars and Antares. Mars is on the top and Saturn is vertically below. Visible to the naked eye, both planets have significance in many cultures around the world. In Roman mythology Mars is the god of war and fertility, and Saturn the god of sowing and agriculture. Its Greek equivalent, the god Kronos, is also considered the regent of completion. Indigenous Australians, including the Kamilaroi and Wailan people, associate Saturn with “wunygal”, a small bird. Mars is called Iherm-penh (something burnt in flames) by the Anmatyerre people of the Central Desert, while the Kokatha people of the Western Desert associate Mars and the star Anatres with the red-tailed black cockatoo (Kogolongo). In the middle of this photograph, the most famous southern constellations are clearly recognisable: the Southern Cross (Crux), the pointer stars, Alpha and Beta Centauri, the dark Coalsack Nebula and the red Eta Carina Nebula, which is not visible to the unaided eye but is prominent in modern photographs. In the 19th century, the star eta Carinae had been the second-brightest star in the sky for some time, but since it varies irregularly, it has hardly been recognisable in recent decades, and its future visibility is unpredictable. Triangulum Australe is visible between the pointer stars and the Scorpion, and in the constellation of Centaurus, the bright globular star cluster Omega Centauri is clearly displayed. It was considered a “nebulous star” since antiquity and, thus, was listed in star catalogues for at least 2000 years. Only within the last century did astronomers discover that globular star clusters are in the halo of our galaxy and that this one consists of roughly 10 million stars. The dark regions in the Milky Way, which are cool, dense clouds of dust and gas, form the head and body of the Celestial Emu Tchingal. Together with the Southern Cross and the pointer stars, they appear in the Dreamtime stories of many Indigenous Australians. One story associated with the Djab Wurrung and the Jardwadjali people is part of a Dreamtime Story involving Tchingal, the Bram-bram-bult brothers (the pointer stars), their mother Druk (Delta Crux), and Bunya the hunter, who gets transformed into a possum (Gacrux, the red star at the top of the Southern Cross).

Caption: 這幅照片捕捉到了火星的天體華爾茲，它在固定恆星的背景下展示了引人入勝的逆行運動。火星在其軌道上出現逆行現象，是由於地球和火星繞太陽運行的速度不同。地球的運動速度較快，偶爾會領先於火星，從我們的角度看去，就會產生這顆紅色星球發生了逆行運動的錯覺。當火星和太陽分別位於地球的兩側，即所謂的“火星沖日”時，這種逆行運動就會發生。從2022年8月14日到2023年4月5日，智能手機拍攝的這幅火星圖像見證了攝影師在菲律賓巴丹的寧靜環境中的堅持不懈和精益求精。攝影師經歷著變幻莫測的天氣和不斷變化的天體排列，每隔五到八天就精心拍攝一次。在整個過程中，攝影師沒有使用任何外部鏡頭或望遠鏡拍攝到了35幅不同的火星圖像，並需要將它們與一幅展現了廣袤星空的背景圖像進行對齊。這幅背景圖像由54幀疊加而成，每幀曝光15秒。融合這些圖像需要對它們進行精確對齊，並對火星進行裁剪，以便使其位置居中，從而在星空背景下顯示火星的逆行。這一復雜的過程通過遮罩將圖像完美無縫地融入背景，突出了火星獨特的運動軌跡。在圖像的右下角，可以看到昴星團。
