Caption: 2021年国际天文学联合会天文摄影大赛第二名，类别：广域星空。 这张全景黎明图像展示了壮丽的银河带——我们的家园星系，由数千亿颗恒星及其他结构组成，其中大部分结构无法用肉眼观测到，甚至在某些情况下也无法直接用望远镜观测到。银河带的外观是因为银河系是一个盘状星系，而我们（地球/太阳系）位于这个盘状结构之中。 世界各地的不同文化和传统对银河都有各自的名称和文化故事。银河中可见的暗区是巨大、密集且寒冷的星云（尘埃和气体云），它们遮蔽了银河中恒星的光。澳大利亚原住民将银河中的暗区与故事联系起来，其中最著名的一个是“天空中的鸸鹋”（在Wotjobaluk地区称为Tchingal）。在银河带及其周围，有各种各样的星团，其中两个熟悉的星团是M6（蝴蝶星团）和M7（托勒密星团）。 地平线上方的亮点是金星（澳大利亚原住民布龙族称之为Chargee Gnowee，太阳的姐姐）。在银河带中，图像中最亮的点是木星（布龙族称之为Ginabongbearp，即硫冠白凤头鹦鹉）。土星是金星和木星之间的亮点（更靠近金星）。 图像中可以轻易辨认出两个星座和一个星群：天鹰座、天蝎座（毛利人和波利尼西亚文化中的Maui’s Hook）和茶壶星群（位于人马座）。在这张图像中，距离地球约26,000光年的银河系中心大致位于茶壶壶嘴的右上方。 木星右侧的亮红橙色点是红超巨星心宿二，是天蝎座的一部分（在毛利人和波利尼西亚文化中称为Maui’s Hook）。恒星颜色的这种变化是恒星温度的结果（温度较低的恒星偏红，温度较高的恒星偏蓝）。

Caption: 2022 年国际天文学联合会 OAE 天体摄影比赛第三名，类别：天体的时间流逝。 本视频以自然为舞台主角，采用戏剧化结构，呈现冰岛与中国两地夜空的万千气象。 序幕由暮色蓝调渐暗展开，陆地云层为幕，壮美地貌为景，揭晓星空舞台。南天银河最摄人心魄的段落——天蝎座（Scorpius）与南十字座（Crux）之间，伴以半人马座α、β星（Alpha/Beta Centauri）这对"指极星"，如王者巡游般庄严划过天际。地面流云轻抚星光，反令恒星的色彩在朦胧中愈发澄明。 第一幕演绎人类文化中的星空意象。当昴星团（Pleiades）自山巅升起时，下方人影持电筒匆匆掠过。恰在昴宿跃出山脊的瞬间，电筒光束直射镜头——这精妙设计以幽默笔触，暗合文明史上人类与"昴宿初升"的深刻羁绊。 随后镜头转向北天经典星座——大熊座（Ursa Major）及其北斗七星，下方极光如拱门舞动。虽形态流转不息，本质却亘古如初。尽管北极文化常将极光视为先祖魂灵，本剧却未着墨人类信仰，径自将视野南移。新场景始于日出前的星辰初升，双子座/金牛座（Gemini/Taurus）区域黄道光锥显现，地平线渐染晨曦。约1分13秒处，猎户座（Orion）西沉于水面，天光云影共徘徊。流云过境印证着地球实景拍摄，而猎户肩足近乎同步沉没的奇观，暗示拍摄地近赤道——在此纬度，猎户亮星恰似巨蝶展翅：三星腰带为躯，四星四边形化翼。 首先，我们看到一些星星在日出前不久升起。黄道十二宫的光锥出现在双子座/金牛座，地平线变得更加明亮。在下一个场景中，大约 1 分 13 秒时，我们看到猎户座落在水面上，因此水面与天体景象相映成趣。一些云层穿过画面，证明这些视频确实是在我们美丽的星球上拍摄的，而且由于猎户座的肩部和脚部几乎同时落下，这组视频一定是在赤道附近拍摄的。在这一区域，猎户座的亮星看起来就像一只巨大的蝴蝶，猎户座腰带构成了蝴蝶的身体，而四颗亮星组成的四边形则被解释为蝴蝶的翅膀。 如真实剧院般，极光幕帘为"天宇戏剧"开启新章。此幕聚焦独特文化星象：既有中国星官体系中的苍龙之尾、箕宿、南斗（对应现代天蝎座与人马座区域），亦展现在全球多文明中被尊为星群的北冕座（Corona Borealis）冠冕轮廓。行星、织女（Vega）、天津四（Deneb）及其周边区域、牛郎（Altair）、银河，以及被地球诸多文明视为星群的仙后座（Cassiopeia）W形标志相继登场。 终章以两幕宁谧星空作结，天地归于大寂。

Caption: 2022 年国际天文学联合会 OAE 天体摄影竞赛 "延时天体图案 "类别荣誉奖。 这幅延时摄影作品是 2020 年 8 月在斯洛伐克拍摄的。通过在部分画面中固定天空与地球自转的相对运动，作为观众的我们可以体验到不同的视角。 银河系，我们的家园星系，在整段视频中清晰可见。银河附近明亮的天体是木星和土星，它们靠得很近，其中木星更亮。 这段视频还展示了业余天文学家用望远镜对准天空观测英仙座流星雨的互动过程。天文观测的一个遗憾是，有时云层会突然遮住整个天空。云雾出现的主要原因是雨后湿度较大。 天空中的大部分亮线都是由卫星造成的，但其中有些出现的时间很短，也不是很明显，它们是流星，因为这段视频是在英仙座流星雨高峰期前后拍摄的。

Caption: 2022年国际天文学联合会（IAU）OAE天文摄影比赛延时天体图案类别荣誉奖作品。 这幅延时摄影作品拍摄于2020年12月，展示了位于南半球智利的圣佩德罗-德阿塔卡马的夜空。 在第一幅画面中，可以看到我们所在的银河系，以及围绕银河系运行的两个卫星星系——大小麦哲伦云。在画面底部，可以看到明亮的恒星南门二和马腹一（也被称为半人马座α星和β星），它们都位于半人马座。在它们正上方，还可以看到北回归线以南可见的南十字座。它对导航非常重要，因为它的长轴指示着南天极的方向。画面顶端，位于银河右侧的亮白色恒星是位于船底座的老人星，它是夜空中最亮的恒星之一。老人星是全天第二亮的恒星，而南门二则是第三亮的恒星。 在接下来的一些画面中，猎户座带着它明亮的恒星和特有的星群——由三颗排列整齐的亮星组成的腰带，清晰地出现在画面中。因为这段视频是从南半球拍摄的，所以这位来自北半球的希腊英雄似乎正在倒立。 我们还能看到木星和土星紧密相合，甚至可在它们周围看到正在缓缓没入地平线的明显光带，那就是黄道光。一些画面中还闪烁着几颗流星，其中一颗流星的尾迹持续时间很长，并在不断延伸。一轮明月从安第斯山脉的火山后面升起，产生了壮观的阴影和曙暮辉光。在最后一幅画面中，我们看到月亮与相合的木星和土星为伴。

Caption: 2022 年国际天文学联合会教育办公室天体摄影比赛“天体延时摄影”类别第一名 这段视频汇集了 2019 年 6 月在智利复活节岛和阿塔卡马沙漠不同时间拍摄的多段录像。开篇呈现出震撼的一幕：云层仿佛从复活节岛著名的石像背后升起，并朝着观察者正面推进，给人一种庄严的神祇召唤云雾遮蔽夜空的神秘氛围。 接下来的几个场景中，我们可以看到壮丽的银河划过头顶，但这片宁静的景象不断被快速划过的卫星所打破——其中一个场景甚至出现了地面汽车灯光的干扰。这一画面既展现了天空的宏伟，也揭示了人类活动对自然的影响。 接下来是另一个云朵掠过的场景，但这次云从左向右移动。地球上的云朵在银河星云之下缓缓穿行。最后一个场景呈现出一片未受干扰的静谧星空，仿佛是在一张放大的天文照片上翱翔。这一幕让人意识到，我们早已习惯了喧嚣的世界，而对大自然的静谧与沉默感到陌生。

Caption: The constellation Sagittarius along with its bright stars and surrounding constellations. Sagittarius is surrounded by (going clockwise from the top) Aquila, Scutum, Serpens Cauda, Ophiuchus, Scorpius, Corona Australis, Telescopium, Microscopium and Capricornus. The brighter stars in Sagittarius form a distinctive teapot shape. Sagittarius lies on the ecliptic (shown here as a blue line), this is the path the Sun appears to take across the sky over the course of a year. The Sun is in Sagittarius from mid December to mid January. The other planets of the Solar System can often be found in Sagittarius. Sagittarius lies south of the celestial equator. The famous teapot asterism is visible for all but the most arctic regions of the world but the most southerly parts of the constellation are not visible in northern parts of Asia, Europe and North America. Sagittarius is most visible in the evenings in the northern hemisphere summer and southern hemisphere winter. The supermassive black hole Sagittarius A* which lies at the center of our Milky Way Galaxy is sits on the western (here right-hand) edge of Sagittarius. Due to it covering an area at the center of our Galaxy, Sagittarius is home to many star clusters including open clusters (marked here with yellow circles) and globular clusters (marked here with yellow circles with + signs superimposed on them). Three nebulae are also marked here with green squares. The y-axis of this diagram is in degrees of declination with north as up and the x-axis is in hours of right ascension with east to the left. The sizes of the stars marked here relate to the star's apparent magnitude, a measure of its apparent brightness. The larger dots represent brighter stars. The Greek letters mark the brightest stars in the constellation. These are ranked by brightness with the brightest star being labeled alpha, the second brightest beta, etc., although this ordering is not always followed exactly. The dotted boundary lines mark the IAU's boundaries of the constellations and the solid green lines mark one of the common forms used to represent the figures of the constellations. Neither the constellation boundaries, nor the line marking the ecliptic, nor the lines joining the stars appear on the sky.

Caption: The constellation Cygnus with its bright stars and surrounding constellations. Cygnus is surrounded by (going clockwise from the top): Cepheus, Draco, Lyra, Vulpecula, Pegasus and Lacerta. Cygnus is notable for its brightest star Deneb. This forms one vertex of the prominent Summer Triangle asterism that is visible in northern hemisphere summer evenings. Cygnus is a northern constellation and thus the whole of the constellation is visible at some point in the year in the whole northern hemisphere. The whole constellation is also visible from equatorial regions of the southern hemisphere with parts of the constellation visible from temperate southern regions. The plane of the Milky Way runs through Cygnus and thus the constellation is rich in nebulae and star clusters. These include the North America Nebula (NGC 7000) and the Crescent Nebula (NGC 6888). The Veil Nebula is a huge supernova remnant, parts of which are marked here as NGC 6960 and NGC 6992/5. All of the previously-mentioned nebulae are marked with green squares. The planetary nebula NGC 6826 is marked here with a green circle superimposed on a plus sign. The open star clusters M29 and M39 are marked here with yellow circles. The y-axis of this diagram is in degrees of declination with north as up and the x-axis is in hours of right ascension with east to the left. The sizes of the stars marked here relate to the star's apparent magnitude, a measure of its apparent brightness. The larger dots represent brighter stars. The Greek letters mark the brightest stars in the constellation. These are ranked by brightness with the brightest star being labeled alpha, the second brightest beta, etc., although this ordering is not always followed exactly.

Caption: The constellation Triangulum with its bright stars and surrounding constellations. Triangulum is surrounded by (going clockwise from the top): Andromeda, Pisces, Aries and Perseus. Triangulum is a northern constellation and thus the whole constellation is visible at some point in the year throughout the northern hemisphere. The whole constellation is also visible from equatorial and most temperate regions of the southern hemisphere. Triangulum is best viewed in the evening in the northern hemisphere winter and southern hemisphere summer. The Triangulum Galaxy M33 lies in the constellation. This spiral galaxy is the third largest member of the local group of galaxies after the Andromeda Galaxy and Milky Way. It is marked here with a red ellipse. The y-axis of this diagram is in degrees of declination with north as up and the x-axis is in hours of right ascension with east to the left. The sizes of the stars marked here relate to the star's apparent magnitude, a measure of its apparent brightness. The larger dots represent brighter stars. The Greek letters mark the brightest stars in the constellation. These are ranked by brightness with the brightest star being labeled alpha, the second brightest beta, etc., although this ordering is not always followed exactly. The dotted boundary lines mark the IAU's boundaries of the constellations and the solid green lines mark one of the common forms used to represent the figures of the constellations. The blue line at the bottom left of the diagram marks the ecliptic. Neither the constellation boundaries, nor the lines joining the stars, nor the ecliptic, appear on the sky.
