Caption: 2021年國際天文學聯合會天文攝影大賽第二名，類別：廣域星空。 這張全景黎明圖像展示了壯麗的銀河帶——我們的家園星系，由數千億顆恆星及其他結構組成，其中大部分結構無法用肉眼觀測到，甚至在某些情況下也無法直接用望遠鏡觀測到。銀河帶的外觀是因為銀河系是一個盤狀星系，而我們（地球/太陽系）位於這個盤狀結構之中。 世界各地的不同文化和傳統對銀河都有各自的名稱和文化故事。銀河中可見的暗區是巨大、密集且寒冷的星雲（塵埃和氣體雲），它們遮蔽了銀河中恆星的光。澳大利亞原住民將銀河中的暗區與故事聯繫起來，其中最著名的一個是“天空中的鸸鹋”（在Wotjobaluk地區稱為Tchingal）。在銀河帶及其周圍，有各種各樣的星團，其中兩個熟悉的星團是M6（蝴蝶星團）和M7（托勒密星團）。 地平線上方的亮點是金星（澳大利亞原住民布龍族稱之為Chargee Gnowee，太陽的姐姐）。在銀河帶中，圖像中最亮的點是木星（布龍族稱之為Ginabongbearp，即硫冠白鳳頭鸚鵡）。土星是金星和木星之間的亮點（更靠近金星）。 圖像中可以輕易辨認出兩個星座和一個星群：天鷹座、天蠍座（毛利人和波利尼西亞文化中的Maui’s Hook）和茶壺星群（位於人馬座）。在這張圖像中，距離地球約26,000光年的銀河系中心大致位於茶壺壺嘴的右上方。 木星右側的亮紅橙色點是紅超巨星心宿二，是天蠍座的一部分（在毛利人和波利尼西亞文化中稱為Maui’s Hook）。恆星顏色的這種變化是恆星溫度的結果（溫度較低的恆星偏紅，溫度較高的恆星偏藍）。

Caption: 2022 年國際天文學聯合會 OAE 天體攝影比賽第三名，類別：天體的時間流逝。 本視頻以自然為舞臺主角，採用戲劇化結構，呈現冰島與中國兩地夜空的萬千氣象。 序幕由暮色藍調漸暗展開，陸地雲層為幕，壯美地貌為景，揭曉星空舞臺。南天銀河最攝人心魄的段落——天蠍座（Scorpius）與南十字座（Crux）之間，伴以半人馬座α、β星（Alpha/Beta Centauri）這對"指極星"，如王者巡遊般莊嚴劃過天際。地面流雲輕撫星光，反令恆星的色彩在朦朧中愈發澄明。 第一幕演繹人類文化中的星空意象。當昴星團（Pleiades）自山巔升起時，下方人影持電筒匆匆掠過。恰在昴宿躍出山脊的瞬間，電筒光束直射鏡頭——這精妙設計以幽默筆觸，暗合文明史上人類與"昴宿初升"的深刻羈絆。 隨後鏡頭轉向北天經典星座——大熊座（Ursa Major）及其北斗七星，下方極光如拱門舞動。雖形態流轉不息，本質卻亙古如初。儘管北極文化常將極光視為先祖魂靈，本劇卻未著墨人類信仰，徑自將視野南移。新場景始於日出前的星辰初升，雙子座/金牛座（Gemini/Taurus）區域黃道光錐顯現，地平線漸染晨曦。約1分13秒處，獵戶座（Orion）西沉於水面，天光雲影共徘徊。流雲過境印證著地球實景拍攝，而獵戶肩足近乎同步沉沒的奇觀，暗示拍攝地近赤道——在此緯度，獵戶亮星恰似巨蝶展翅：三星腰帶為軀，四星四邊形化翼。 首先，我們看到一些星星在日出前不久升起。黃道十二宮的光錐出現在雙子座/金牛座，地平線變得更加明亮。在下一個場景中，大約 1 分 13 秒時，我們看到獵戶座落在水面上，因此水面與天體景象相映成趣。一些雲層穿過畫面，證明這些視頻確實是在我們美麗的星球上拍攝的，而且由於獵戶座的肩部和腳部幾乎同時落下，這組視頻一定是在赤道附近拍攝的。在這一區域，獵戶座的亮星看起來就像一隻巨大的蝴蝶，獵戶座腰帶構成了蝴蝶的身體，而四顆亮星組成的四邊形則被解釋為蝴蝶的翅膀。 如真實劇院般，極光幕簾為"天宇戲劇"開啟新章。此幕聚焦獨特文化星象：既有中國星官體系中的蒼龍之尾、箕宿、南斗（對應現代天蠍座與人馬座區域），亦展現在全球多文明中被尊為星群的北冕座（Corona Borealis）冠冕輪廓。行星、織女（Vega）、天津四（Deneb）及其周邊區域、牛郎（Altair）、銀河，以及被地球諸多文明視為星群的仙後座（Cassiopeia）W形標誌相繼登場。 終章以兩幕寧謐星空作結，天地歸於大寂。

Caption: 2022 年國際天文學聯合會 OAE 天體攝影競賽 "延時天體圖案 "類別榮譽獎。 這幅延時攝影作品是 2020 年 8 月在斯洛伐克拍攝的。通過在部分畫面中固定天空與地球自轉的相對運動，作為觀眾的我們可以體驗到不同的視角。 銀河系，我們的家園星系，在整段視頻中清晰可見。銀河附近明亮的天體是木星和土星，它們靠得很近，其中木星更亮。 這段視頻還展示了業餘天文學家用望遠鏡對準天空觀測英仙座流星雨的互動過程。天文觀測的一個遺憾是，有時雲層會突然遮住整個天空。雲霧出現的主要原因是雨後溼度較大。 天空中的大部分亮線都是由衛星造成的，但其中有些出現的時間很短，也不是很明顯，它們是流星，因為這段視頻是在英仙座流星雨高峰期前後拍攝的。

Caption: 2022年國際天文學聯合會（IAU）OAE天文攝影比賽延時天體圖案類別榮譽獎作品。 這幅延時攝影作品拍攝於2020年12月，展示了位於南半球智利的聖佩德羅-德阿塔卡馬的夜空。 在第一幅畫面中，可以看到我們所在的銀河系，以及圍繞銀河系運行的兩個衛星星系——大小麥哲倫雲。在畫面底部，可以看到明亮的恆星南門二和馬腹一（也被稱為半人馬座α星和β星），它們都位於半人馬座。在它們正上方，還可以看到北迴歸線以南可見的南十字座。它對導航非常重要，因為它的長軸指示著南天極的方向。畫面頂端，位於銀河右側的亮白色恆星是位於船底座的老人星，它是夜空中最亮的恆星之一。老人星是全天第二亮的恆星，而南門二則是第三亮的恆星。 在接下來的一些畫面中，獵戶座帶著它明亮的恆星和特有的星群——由三顆排列整齊的亮星組成的腰帶，清晰地出現在畫面中。因為這段視頻是從南半球拍攝的，所以這位來自北半球的希臘英雄似乎正在倒立。 我們還能看到木星和土星緊密相合，甚至可在它們周圍看到正在緩緩沒入地平線的明顯光帶，那就是黃道光。一些畫面中還閃爍著幾顆流星，其中一顆流星的尾跡持續時間很長，並在不斷延伸。一輪明月從安第斯山脈的火山後面升起，產生了壯觀的陰影和曙暮輝光。在最後一幅畫面中，我們看到月亮與相合的木星和土星為伴。

Caption: 2022 年國際天文學聯合會教育辦公室天體攝影比賽“天體延時攝影”類別第一名 這段視頻彙集了 2019 年 6 月在智利復活節島和阿塔卡馬沙漠不同時間拍攝的多段錄像。開篇呈現出震撼的一幕：雲層仿佛從復活節島著名的石像背後升起，並朝著觀察者正面推進，給人一種莊嚴的神秖召喚雲霧遮蔽夜空的神祕氛圍。 接下來的幾個場景中，我們可以看到壯麗的銀河劃過頭頂，但這片寧靜的景象不斷被快速劃過的衛星所打破——其中一個場景甚至出現了地面汽車燈光的乾擾。這一畫面既展現了天空的宏偉，也揭示了人類活動對自然的影響。 接下來是另一個雲朵掠過的場景，但這次雲從左向右移動。地球上的雲朵在銀河星雲之下緩緩穿行。最後一個場景呈現出一片未受乾擾的靜謐星空，仿佛是在一張放大的天文照片上翱翔。這一幕讓人意識到，我們早已習慣了喧囂的世界，而對大自然的靜謐與沉默感到陌生。

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.
