Glossary term: 雙魚座

Description: 雙魚座是黃道帶上的一個星座,也就是說,組成這個星座的恆星位於與黃道(由地球繞太陽運行的軌跡所確定的平面)相交的那部分天空。因此,從我們在地球上的視角來看,我們會發現太陽和行星經常落在雙魚座中。就太陽而言,這發生在每年3月中旬到4月中旬,春分節氣就包含在其中。(當然,要是太陽位於雙魚座,我們就看不到雙魚座中的恆星了。)雙魚座是國際天文學聯合會定義的88個現代星座之一,但其歷史可以追溯到更久遠的年代——它是公元2世紀的天文學家克羅狄斯·托勒密(Claudius Ptolemy)命名的48個星座之一。

在銀河的前方,我們可以看到沙漏狀的獵戶座和明亮的昴宿星團。

斯皮什地區的暖冬之夜

Caption: 2022 年國際天文學聯合會 OAE 天體攝影比賽靜態天體圖案類獲獎作品。 這張照片於 2022 年 1 月在斯洛伐克拍攝,展現了銀河的廣袤區域與繁複的星座群像。北半球夏季星座低垂於畫面右下方,天鵝座與天琴座的亮星穿透地平線的人造光源。冬季與秋季星座群集北天,諸多明亮恆星承載著多元文化敘事。 北美拉科塔人將獵戶座腰帶視為野牛脊柱("Tayamnicankh, 塔亞姆尼坎克")。在希臘神話中,獵戶座常被描述為獵人,追逐著昴星團七姐妹,而阿拉伯傳統將追逐者簡化為單星——金牛座右眼恆星畢宿五(Aldebaran),其名源自阿拉伯語"al-dabaran"(追隨者)。 畫面右下方地平線處,黃道光從雙魚座經白羊座延伸至昴星團附近,勾勒出行星與月球的運行軌跡。昴星團與畢宿星團在此路徑上形成"天界之門",天體偶爾會穿過此門進入銀河。古巴比倫人將行星視為綿羊,獵戶座則被稱作"天界真牧者",其牧杖延伸至黃道。羅馬傳統中,昴星團與銀河上方的亮白恆星五車二(Capella)被視作山羊,可追溯至該區域的埃及古星座。 畫面中右部樹冠上方可見秋季四邊形、仙女座星系與W形仙後座。其左側銀河中央區域是英仙座,仙後座上方的仙王座則補全天界家族圖譜。仙女座傳說源自今以色列地區的希臘故事,根植於敘利亞傳統——古巴比倫人視其區域為愛欲女神之地,敘利亞人則視為豐饒女神之所。傳說中仙女座被鎖於雅法(今特拉維夫)海岸的礁石上,英雄珀爾修斯(其名可能意為"波斯人",今伊朗)將其救贖。 山谷中可見城鎮燈火,地平線上方的黃色光暈來自於光汙染嚴重的大城市。

寶瓶座看起來像一系列蜿蜒相連的線條,其輪廓綿延展開。黃道從西南偏西(WSW)方向延伸至東北偏東(ENE)方向,貫穿了寶瓶座的中心。

寶瓶座星圖

Caption: 寶瓶座及其明亮恆星與周邊星座示意圖。從頂部開始沿順時針方向,寶瓶座周邊的星座依次為:飛馬座、小馬座、天鷹座、摩羯座、南魚座、玉夫座、鯨魚座和雙魚座。寶瓶座位於黃道上。從地球看來,太陽以一年為週期在天球上移動,所經過的路徑稱為黃道,在圖中以藍色實線標注。太陽在每年二月中旬到三月中旬位於寶瓶座。太陽系中的其他行星也經常出現在寶瓶座。 寶瓶座橫跨天赤道,因此在地球上的任何地方,一年中的某些時候都能看到它。在地球南北兩極,寶瓶座的某些部分可能不可見。寶瓶座在北半球的秋季和南半球的春季夜晚最適宜觀測。 球狀星團M2和M72在圖中以疊加了十字符號的黃色圓圈標注。行星狀星雲NGC 7293(螺旋星雲)和NGC 7002(土星狀星雲)在圖中以疊加了十字符號的綠色圓圈標注。M73在圖中以叉號標注,它是一個偶然形成的恆星群,之前被錯誤歸類為疏散星團。 該圖的縱軸為赤緯,橫軸為赤經,方向為上北下南左東右西。圖中標注的恆星大小對應其視星等——衡量天體視亮度的標準,較大的圓點代表著較亮的恆星。圖中的希臘字母標注著星座中最亮的恆星。這些恆星按亮度排序,最亮的一般被標記為α星,第二亮的一般為β星,等等,不過這種字母排序並不總是和實際亮度排序完全一致。圖中虛線標注的是國際天文學聯合會劃定的星座邊界,綠色實線則是一種常見的星座形象連線。需要注意的是,在實際觀測時,這些邊界與連線都不會出現在天空中。

雙魚座呈現為指向西南的V字形,每條線的末端都帶有一個環。黃道從西南偏西(WSW)方向延伸至東北偏東(ENE)方向,貫穿了雙魚座。

雙魚座星圖

Caption: 雙魚座及其明亮恆星與周邊星座示意圖。從頂部開始沿順時針方向,雙魚座周邊的星座依次為:仙女座、飛馬座、寶瓶座、鯨魚座、白羊座和三角座。雙魚座位於黃道上。從地球看來,太陽以一年為週期在天球上移動,所經過的路徑稱為黃道,在圖中以藍色實線標注。太陽在每年三月中旬到四月中旬位於雙魚座。因此,春分時太陽位於雙魚座——黃道在這裡與天赤道相交,而太陽在春分時的位置即為赤道坐標系中赤經坐標的原點。太陽系中的其他行星也經常出現在雙魚座。 雙魚座橫跨天赤道,因此在地球上的任何地方,一年中的某些時候都能看到它。在地球南北兩極,雙魚座的某些部分可能不可見。雙魚座在北半球的秋季和南半球的春季夜晚最適宜觀測。 宏偉的螺旋星系M74在圖中以紅色小圓圈標注。 該圖的縱軸為赤緯,橫軸為赤經,方向為上北下南左東右西。圖中標注的恆星大小對應其視星等——衡量天體視亮度的標準,較大的圓點代表著較亮的恆星。圖中的希臘字母標注著星座中最亮的恆星。這些恆星按亮度排序,最亮的一般被標記為α星,第二亮的一般為β星,等等,不過這種字母排序並不總是和實際亮度排序完全一致。圖中虛線標注的是國際天文學聯合會劃定的星座邊界,綠色實線則是一種常見的星座形象連線。需要注意的是,在實際觀測時,這些邊界與連線都不會出現在天空中。

白羊座內的亮星很少,僅有的幾顆亮星位於其北部,在圖中以曲線相連。黃道從西南偏西(WSW)方向延伸至東北偏東(ENE)方向。

白羊座星圖

Caption: 白羊座及其明亮恆星與周邊星座示意圖。從頂部開始沿順時針方向,白羊座周邊的星座依次為:三角座、雙魚座、鯨魚座、金牛座和英仙座。白羊座位於黃道上。從地球看來,太陽以一年為週期在天球上移動,所經過的路徑稱為黃道,在圖中以藍色實線標注。太陽在每年四月中旬到五月中旬位於白羊座。因太陽系中的其他行星也經常出現在白羊座。 白羊座位於天赤道的正北方,因此在地球上,除了南極地區以外,一年中的某些時候都能看到它。白羊座在北半球的冬季和南半球的夏季夜晚最適宜觀測。 該圖的縱軸為赤緯,橫軸為赤經,方向為上北下南左東右西。圖中標注的恆星大小對應其視星等——衡量天體視亮度的標準,較大的圓點代表著較亮的恆星。圖中的希臘字母標注著星座中最亮的恆星。這些恆星按亮度排序,最亮的一般被標記為α星,第二亮的一般為β星,等等,不過這種字母排序並不總是和實際亮度排序完全一致。圖中虛線標注的是國際天文學聯合會劃定的星座邊界,綠色實線則是一種常見的星座形象連線。需要注意的是,在實際觀測時,這些邊界與連線都不會出現在天空中。

Pegasus appears as a square with lines extending west from its western two vertices

Pegasus Constellation Map

Caption: The constellation Pegasus with its bright stars and surrounding constellations. Pegasus is surrounded by (going clockwise from the top): Lacerta, Cygnus, Vulpecula, Delphinus, Equuleus, Aquarius, Pisces and Andromeda. Pegasus is known for the prominent asterism the “Square of Pegasus” which consists of its three brightest stars plus the brightest star in Andromeda. Pegasus 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 to southern hemisphere equatorial and temperate zones with parts of the constellation visible from all but the most antarctic regions. Pegasus is best viewed in the evening in the northern hemisphere autumn and southern hemisphere spring. The globular cluster M15 lies in Pegasus and is marked here with a yellow circle with a plus sign superimposed on it. The spiral galaxy NGC 7331 also lies in Pegasus and 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 of the diagram marks the ecliptic. Neither the constellation boundaries, nor the lines joining the stars, nor the ecliptic, appear on the sky.

The bright stars in Triangulum form an isosceles triangle pointing south west

Triangulum Constellation Map

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.
