Glossary term: 人马座

Description: 人马座是黄道带上的一个星座,也就是说,组成这个星座的恒星位于与黄道(由地球绕太阳运行的轨迹所确定的平面)相交的那部分天空。因此,从地球上看,我们会发现太阳和太阳系的其他行星经常落在人马座中。就太阳而言,这发生在每年12月下旬到1月上旬。(当然,那时我们看不到人马座中的恒星。)人马座是国际天文学联合会定义的88个现代星座之一,但其历史可以追溯到更久远的年代——它是公元2世纪的天文学家克罗狄斯·托勒密(Claudius Ptolemy)命名的48个星座之一。值得注意的是,我们银河系的中心就位于人马座,那里有着超大质量黑洞——人马座A*。

非洲草原上方的银河拱门。银河的弥散光被一串暗斑打断。

安波塞利国家公园上空的银河拱门

Caption: 2022年国际天文学联合会(IAU)OAE天文摄影比赛静态天体图案类别获奖作品。 这张照片2016年7月拍摄于肯尼亚安博塞利国家公园,该公园位于赤道附近。 在北非的埃及神话中,银河被看作神灵所航行的河流。南非的祖鲁人将这种由明暗星云组成的图案解释为一种皮肤黑白相间的动物,而南非的科伊科伊人和桑人则认为它是“星路”。在南非的一些文化中,银河的拱门是一位母神创造的通往天堂的道路——这是19世纪的早期人类学研究所采纳的一个南非创世神话,但这一神话如今已经消失。 在照片的右中部,我们可以看到现代天蝎座中明亮的红色恒星心宿二。照片左上角边缘是白色的织女星,开普敦附近的人认为它是雄性的骏马。 澳大利亚原住民对银河有很多称呼。澳大利亚北领地阿纳姆地区的约尔努(Yolnu)人称呼银河为“Milnguya”,意为“天河”。这张照片中的一个突出图案与银河的明暗区域对比有关。 这些暗区是由星际尘埃和气体组成的低温致密云团,阻挡了其背后恒星发出的光线。其中一个突出的图案被澳大利亚南部几个土著民族称为“Tchingal”,意为“天上的鸸鹋”。鸸鹋的头部和嘴部(即煤袋星云)位于南十字座(照片右下角)的左下方,身体和腿部则从南十字座向左延伸。其他原住民群体则将暗区与洞穴或水道联系在一起。鸸鹋一年四季的朝向提供了重要的线索,表明什么时候应该采集鸸鹋蛋,什么时候鸸鹋蛋开始孵化。在某些月份,当这些银河暗云靠近地平线时,人们则认为它们不是鸸鹋,而是两条匍匐前进的鳄鱼。 在银河系中心的上方,可以清楚地看到黑暗的烟斗星云的现代形象。银河上方那颗橙红色的恒星是天蝎座的心宿二,而烟斗的烟雾可以到达心宿二旁边色彩斑斓的蛇夫座ρ区域。波隆人把心宿二称为“Djuit”,意为“红腰鹦鹉”;而西部沙漠的科卡塔人则把心宿二称为“Kogolongo”,意为“红尾黑凤头鹦鹉”。 此外,照片中还可以看到一些著名的星座:天鹅座、天鹰座、天琴座、天蝎座、人马座、南十字座和半人马座。在南非的一些传统中,指针星——半人马座α星(南门二)和β星(马腹一)偶尔被视为野兽的眼睛。

A starry sky, including the diffuse glow of the Milky Way behind a stepped mud brick pyramid.

Galaxy Arm

Caption: Honourable mention in the 2022 IAU OAE Astrophotography Contest, category Still images of celestial patterns.   Taken from the south of Iraq in January 2022, this image shows a clear sky over one of the many ancient monuments in the region which looks like a Babylonian ziggurat. The Sumerians had invented these mountain-like buildings even before the invention of script; the earliest ziggurats appear around 4000 years before the common era. They look like the frustum of a pyramid and in Babylonian times often had temples on top. Next to the stairs of the ziggurat are the constellations of the southernmost part of the Zodiac, also invented in Babylon. Today, we call them Capricorn (left, with a planet in it) and Sagittarius, whose brightest stars form the asterism of the Teapot. For the Babylonians, Sagittarius was the god Pabilsang, the city god of Larak and a god of agriculture and war. He was also the husband of the mighty goddess of medicine, Gula, and his iconography is a hybrid creature holding a bow and arrow: a male human torso and head attached to the body of a horse with four legs, two gigantic wings and two tails — a horse tail and a scorpion tail. Such a creature did not exist in Greek mythology, so the Greeks reduced it to something they knew, a centaur holding a bow and arrow. This picture still did not make sense in Greek culture because centaurs were considered wild and cruel, and not intelligent enough to use a bow and arrow. Therefore, there was another Greek figure that existed simultaneously: a man with hooves instead of feet at the ends of his legs, a satyr, but this figure vanished in Roman times.  Capricornus is one of the most stable foreign creatures in the Zodiac and has been unchanged over millennia. It is depicted as a hybrid creature with the front part of a goat and the back part of a fish. This so-called Goat-Fish constellation has been recognised since the earliest writings of astronomy in Babylon. In Babylonian religion it is a good-natured, benevolent demon that protects humans, supports all healing processes and accompanies the god of wisdom and witchcraft. The Greeks simply adopted it and invented a saga for it. In Roman times, it became tremendously famous because emperor Augustus of Rome used it as his personal symbol, also imprinting it on coins and other political propaganda tools. In Sagittarius, there is also the bright bulge of the Milky Way. That this is hardly visible in this photograph is a result of modern civilization; the huge number of artificial lights that we use on Earth also illuminates the night sky and makes it impossible to see the Milky Way in areas where humans live.

The diffuse glow of the Milky Way broken by dark patches. Right, the red star Antares forms the top of a hook-like pattern

Milky Way Arch over La Palma

Caption: Winner in the 2022 IAU OAE Astrophotography Contest, category Still images of celestial patterns.   This image, which shows the majestic band of the Milky Way and a range of culturally significant patterns, was taken in May 2022 at a very high altitude from the Roque de los Muchachos Observatory in La Palma, from which one can see the clouds below. Some prominent star patterns include Scorpius, Sagittarius, Lyra, Cygnus, Aquila, the Summer Triangle asterism, and the Teapot asterism. As the Canary Islands used to be a starting point for European sailors to explore the world, we use this place to point to the many indigenous cultures they encountered. Most notably it is the dark patterns within the band of the Milky Way that hold significance for many Indigenous cultures around the world. The dark patterns are in fact dense, cool clouds of gas and dust that block the light from stars. Indigenous people see caves, waterways and various patterns associated with the dark regions of the Milky Way. The constellations and patterns hold different cultural significance and interpretations for different people. For example, the constellation Scorpius is referred to by Polynesian people as the demigod Maui’s Fishhook. The Yolnu people of Arnhem Land associate Scorpius with a crocodile called Ingalpir. Some Indigenous Australian groups associate stories with individual stars within Scorpius, most notably Antares, the orange-red star in the top right of the image above the band of the Milky Way. Next to the Scorpion and above the bright centre of the Milky Way, there is a prominent dark cloud that is called the Pipe Nebula by modern astrophotographers. The smoke of this pipe goes up to rho Ophiuchi. This and all the other dark clouds in the Milky Way together form the backbone of heaven for some tribes, and an animal with black-and-white skin for South African Zulu people. The nomenclature of bright stars also has cross-cultural roots. For example, Vega (the bright blue star towards the top of the image) comes from the Arabic waqi, from al-nasr al-waqi, the Eagle who throws himself down (in order to hunt). This contrasts with the Flying Eagle, Altair, also derived from Arabic. Antares is a Greek word meaning “the one similar to Mars”, referring to its colour. The star name Shaula in the stinger of the Scorpion is a modern version of the Babylonian or even Sumerian star name.

The Milky Way arches over a mountain-top building. Its diffuse glow is broken by dark patches and is brighter on the right

The Moon and Milky Way arch Above the Golden Hall

Caption: Winner in the 2022 IAU OAE Astrophotography Contest, category Still images of celestial patterns.   Taken in April 2021 from the top of the Laojun Mountain in China, this image shows a panoramic view of the Milky Way over the Golden Hall called “Yuhuangding” as a symbol of wealth. In China, the Milky Way is considered a huge stream like one of the big rivers. It separates the Cowherd (Altair) and his beloved Weaving Girl (Vega) and it has a Celestial Ford in the northern dark cloud in the modern constellation Cygnus. The Milky Way appears as a whitish arch as we cannot distinguish all the individual stars, but instead see the accumulation of light from them. It is a disc-shaped galaxy and the Solar System is located within one of its spiral arms, so we see it from inside, which gives it the shape of a band in our sky. It is associated with the religions and mythologies of several cultures. The modern term Milky Way derives from Greek folklore as the milk spread in the sky by the mother goddess Hera, when she unwillingly breastfed young Heracles. This son of Zeus and a mortal woman was put next to her while she was asleep but from his strong sucking she woke up and realised she was feeding an unknown child, and immediately pushed the child away. Greek philosophers like Plato considered the glittering band in the sky to be the traces of a former path of the Sun. Alternatively, for the Tupi-Guarani indigenous mythology from South America, the Milky Way represents the “path of tapir”. For some Australian native peoples, its dark clouds formed the shape of an emu if high in the sky, and of crocodiles if low on the horizon. For many southern African, South American and Australian cultures, it was considered a pathway to or from heaven. At the right edge of the image, we can recognise the modern constellation Scorpius with its most prominent star, Antares, the reddish star just above the Milky Way. The brightest point seen in the centre bottom of the image is the rising Moon with Jupiter next to it. A few constellations can be distinguished in this image, including Corona Australis, a faint arc-shaped constellation located to the bottom right. Just above the Southern Crown, we can see the Teapot asterism as part of the Sagittarius constellation. Since Sagittarius lies next to the centre of the Milky Way, many structures such as star-forming regions, globular clusters and planetary nebulae can be found within its boundaries. In Sagittarius, we also find a supermassive black hole four million times as massive as our Sun. At the left side of the band, we can identify the bright star Deneb in the constellation Cygnus, The Swan, through which the Milky Way runs, meaning that a variety of star clusters are found in this constellation.

The bright Moon is reflected in a pool of water. The diffuse light and dark patches of the Milky Way dominate the top right

Lyrid of the Lake

Caption: Winner in the 2022 IAU OAE Astrophotography Contest, category Still images of celestial patterns.   Taken in the early hours of 24 April 2022, this image captures the sky of Yunnan Province, China, with a reflection on Lake Nian. The Milky Way is visible on the left side, while whitish Earth clouds are visible on the right. A Lyrid meteor crosses the sky along the Milky Way, its tail pointing back toward the shower's radiant in the constellation Lyra, which lies outside the image above the upper edge. The natural colours of the meteor are impressively clear. A few constellations are also visible. In the top left corner we can recognise the small constellation of the Dolphin, in which five brightest stars comprise the asterism. This asterism forms the head-part of the larger Greek constellation of the Dolphin and was considered the Dolphin since Roman times, when Ptolemy formed the new constellation of Equuleus in the southern part of the original figure. In mediaeval China, this asterism was considered the Good and the Rotten Gourd, the good one being formed by the brighter rhombus on the top and the rotten one made of faint stars in the tail of the Roman dolphin. The bright star to the right of the Dolphin and at the top of the image is Altair, the brightest star in the constellation Aquila. In Chinese uranology, Altair, together with some adjacent areas, forms the constellation of the Drum at the River. However, in Chinese folklore, the bright star stands for a boy in love with a girl, who is represented by the bright star Vega (in Lyra) on the other side of a huge celestial stream, the Milky Way. Vega is not visible in this image but the Lyrid meteor is like a teardrop of the unlucky girl who cannot reach her lover. In the upper right of the image, the constellation Scorpius shines with its bright reddish star Antares. With some of its neighbouring stars, it was regarded in China as the asterism of The Heart, which was also one of the Lunar Mansions. It was considered the heart of the Azure Dragon, the super-constellation of spring, in ancient China. Scorpius and Sagittarius, in the middle of the image, contain the brightest clouds of the Milky Way, the Galactic Centre, which also has clearly visible dark clouds in front of the bright ones. There is no classical Greco-Roman constellation between Aquila and Scorpius, but in the 17th century, two Polish astronomers, the couple Jan and Elizabeta Hevelius, named this area of bright clouds in the Milky Way Scutum, the Shield, in memory of a Polish king. In China, however, this area directly outside the super-constellation (or heavenly enclosure) of the Celestial Market Place was seen as depicting Market Officers.

Scorpius Constellation Map

Caption: The constellation Scorpius (often commonly called Scorpio) along with its bright stars and surrounding constellations. Scorpius is surrounded by (going clockwise from the top) Ophiuchus, Serpens Caput, Libra, Lupus, Norma, Ara, Corona Australis and Sagittarius. Scorpius’s brightest star Antares appears in the heart of the constellation with the famous tail of Scoprius in the south-east (lower left). Scorpius 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 only spends a short amount of time in late November in Scorpius. The other planets of the Solar System can often be found in Scorpius. Scorpius lies south of the celestial equator. The whole constellation is not visible from the most arctic regions of the world with parts of Scorpius obscured for observers in northern parts of Asia, Europe and North America. Scorpius is most visible in the evenings in the northern hemisphere summer and southern hemisphere winter. The yellow circles mark the positions of the open clusters M6, M7 & NGC 6231 while the yellow circles with plus signs superimposed on them mark the globular clusters M4 and M80. 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 circle around Antares indicates that it is a variable star. 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 lines joining the stars appear on the sky. The blue line marks the ecliptic, the path the Sun appears to travel across the sky over the course of one year.

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.

Capricornus Constellation Map

Caption: The constellation Capricornus (commonly called Capricorn) including its bright stars and surrounding constellations. Capricornus is surrounded by (going clockwise from the top) Aquarius, Aquila, Sagittarius, Microscopium and Piscis Austrinus. Capricornus 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 Capricornus from mid January to mid February. The other planets of the Solar System can often be found in Capricornus. Capricornus lies just south of the celestial equator and is visible to all observers south of the Arctic Circle. Capricornus is most visible in the evenings in the northern hemisphere autumn and southern hemisphere spring. In the south east (lower left on this diagram) of the constellation one can find the globular cluster M30 (shown here as a yellow circle with a plus sign superimposed on it). 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.

Ophiuchus appears as a headless stick figure

Ophiuchus Constellation Map

Caption: The constellation Ophiuchus along with its bright stars and its surrounding constellations. Ophiuchus is surrounded by (going clockwise from the top): Hercules, Serpens Caput, Scorpius, Sagittarius and Serpens Cauda. Ophiuchus is not part of the traditional twelve zodiac constellations but it 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 Ophiuchus from late November to mid December. The other planets of the Solar System can often be found in Ophiuchus. Ophiuchus spans the celestial equator and thus part of the constellation is visible across the whole of the earth at some point in the year. However during the time it is most visible in the evenings (the southern hemisphere winter and northern hemisphere summer) much of the arctic is in perpetual daylight making the stars in the constellation impossible to see. The whole constellation is visible from equatorial and temperate regions of both hemispheres. As Ophiuchus lies close to the galactic center it contains many globular clusters such as M9, M10, M12, M14, M19, M62, and M107. These are marked as yellow circles with plus symbols superimposed. 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.

Corona Australis Constellation Map

Caption: The constellation Corona Australis with its brighter stars and surrounding constellations. Corona Australis is surrounded by (going clockwise from the top): Sagittarius, Scorpius, Ara and Telescopium. This constellation has relatively few bright stars. Corona Australis is a southern constellation and thus the whole constellation is visible in the southern hemisphere at some point in the year. The constellation can also be viewed from equatorial and some temperate regions of the northern hemisphere. The constellation is best viewed in the evening in the northern hemisphere summer and southern hemisphere winter. The globular cluster NGC 6541 lies in Corona Australis and is marked here with a yellow circle with a plus sign superimposed on it. 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.
