Caption: 这张由美国宇航局火星勘测轨道飞行器于 1999 年拍摄的火星图像显示了火星干燥的表面。这张照片展示了火星上最壮观的地质区域。除了深邃的马林里斯谷之外，我们还看到了四座火山。其中三座形成了塔西斯山脊，而奥林帕斯火山则是我们迄今为止在太阳系中发现的最大的火山。冰云覆盖了火星表面的部分区域。

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: 这幅照片捕捉到了火星的天体华尔兹，它在固定恒星的背景下展示了引人入胜的逆行运动。火星在其轨道上出现逆行现象，是由于地球和火星绕太阳运行的速度不同。地球的运动速度较快，偶尔会领先于火星，从我们的角度看去，就会产生这颗红色星球发生了逆行运动的错觉。当火星和太阳分别位于地球的两侧，即所谓的“火星冲日”时，这种逆行运动就会发生。从2022年8月14日到2023年4月5日，智能手机拍摄的这幅火星图像见证了摄影师在菲律宾巴丹的宁静环境中的坚持不懈和精益求精。摄影师经历着变幻莫测的天气和不断变化的天体排列，每隔五到八天就精心拍摄一次。在整个过程中，摄影师没有使用任何外部镜头或望远镜拍摄到了35幅不同的火星图像，并需要将它们与一幅展现了广袤星空的背景图像进行对齐。这幅背景图像由54帧叠加而成，每帧曝光15秒。融合这些图像需要对它们进行精确对齐，并对火星进行裁剪，以便使其位置居中，从而在星空背景下显示火星的逆行。这一复杂的过程通过遮罩将图像完美无缝地融入背景，突出了火星独特的运动轨迹。在图像的右下角，可以看到昴星团。
