Caption: Winner in the 2022 IAU OAE Astrophotography Contest, category Still images of celestial patterns.   This image, taken from the Avenue of Baobabs, Morondava, Madagascar, in July 2017, shows the majestic band of the Milky Way, our home galaxy, together with a rich collection of constellations and asterisms: Crux, Centaurus, Scorpius, Sagittarius and the Teapot asterism. Towards the bottom left of the image we can see the Southern Cross and the pointer stars Alpha (the brighter of the two) and Beta Centauri, which help to distinguish it from similar-looking configurations. Some cultures in Africa associate the Southern Cross with a giraffe, while others associate the constellations with a pride of lions or even with the Tree of Life. Antares, the brightest star in the constellation Scorpius, is the orange-red star straight up from the middle baobab tree. To the Pokomo people from southwestern Kenya, Africa, the Milky Way is associated with the smoke emanating from a campfire lit by ancient people. The various people in South Africa, in contrast, have different star tales; the Khoikhoi from the region around Cape Town explained the colours of the red and white stars as red and white roots that were roasted on a fire and thrown towards the sky together with the ashes of the fire. The Xhosa from further east consider the Milky Way the raised bristle of a huge angry dog, while the Zulu from near Johannesburg interpret it as a stream of spears of their strongest warriors. Polynesian people, who were adept seafarers and navigators, see the constellation Scorpius as a fish hook, and refer to it as the demigod Maui’s Fish Hook. For the Djab Wurrung and the Jardwadjali people, the Southern Cross 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 changed into a possum (Gacrux, red star at the top of the Southern Cross). In this image, the planets Saturn (the bright point above Antares) and Jupiter (the bright point at the bottom-right of the image close to the trunk of the baobab tree) are visible. Indigenous cultures have various stories associated with the planets, for example Kamilaroi and Wailan people associate Saturn with wunygal, a small bird. The Boorong people of Western Victoria associate Jupiter with Ginabongbearp, the chief of the old spirits (Nurrumbunguttias), who takes the totemic form of the sulphur-crested white cockatoo.

Caption: Honourable mention in the 2022 IAU OAE Astrophotography Contest, category Still images of celestial patterns.   This image shows the Milky Way crossing the sky above the historical Bixby Bridge in Big Sur, a mountainous region in California, USA, in May 2021. The star directly above the shore is Antares, a red supergiant in the heart of the Scorpion. To its left, the clouds of the Milky Way seem to emerge from the same point of the horizon as the rocky landmass. Above the land, below the Milky Way in the left quarter of the image, is another bright star, Altair, the bright star in Aquila, the Eagle. The scorpion is considered a dangerous animal, so scorpion-men (human-scorpion hybrids) guarded the gate to the Netherworld in ancient Babylonian stories, as reported in the Gilgamesh saga. The Eagle, in contrast, appears in the Babylonian saga of King Etana who was taken to the sky by an Eagle and describes the world that he sees below him with increasing distance. Both heroes, Gilgamesh and Etana, are searching for the “herb of life” but one of them by going down, the other by travelling upwards. Gilgamesh aims to get back his dead friend Enkidu and to become immortal himself, while Etana is seeking the herb to help his wife become pregnant. The scorpion and the eagle are the animals supporting these heroes in their search, that ultimately remained unsuccessful. Gilgamesh finally learned that humans can only become immortal by their good deeds for humanity. The Eagle was also recognised in Greek culture, but it was only in Roman times that it became a messenger of a dead soul, carrying it towards the eternal stars. This was when Ptolemy created a constellation to represent the soul of Antinuous below the classical Eagle. This young friend and consultant of the Roman emperor Hadrian drowned in the Nile only seven years before the completion of the Almagest, and the whole Roman empire observed a state of national mourning. The Milky Way is seen as a “pathway of souls” by many cultures, but in the Babylonian culture, this is not the case. Still, in Greco-Roman philosophy, the bright white parts of it between Antares and Altair, at the intersection of the Milky Way and the Zodiac do have a meaning: Plato, Macrobius and other philosophers refer to it as “the X in the sky”, and the second Celestial Gate was probably considered to be here (the first one being the gate formed by the Hyades and Pleiades). These celestial pathways and gates, depicted above a gigantic bridge in the landscape and a site where the realms of land and ocean meet, make for an incredibly charged photograph. Additionally, the dark clouds in the Milky Way directly above the land form one of the two large dark constellations of the crocodiles, as interpreted by some people in southern Australia.

Caption: Winner in the 2022 IAU OAE Astrophotography Contest, category Still images of celestial patterns.   This image was taken in July 2016 from the Amboseli National Park in Kenya, located close to the equator. In Egyptian mythology from northern Africa, the Milky Way was associated with a river sailed by gods and souls. The Zulu in South Africa interpret this pattern of dark and bright clouds of stars as an animal with black and white skin, whereas the South African Khoikhoi and San considered it “The Star’s Road”. In several South African cultures, the arch of the Milky Way is a pathway to the heavens formed by a mother goddess, according to a South African creation myth that was adopted in the 19th century from early ethnological research, but has vanished today. In the middle-right of the image we find the bright red star Antares in the modern constellation of the Scorpion and at the upper-left edge is the white star Vega that is considered a Male Steenbok by the peoples around Cape Town. Indigenous Australians have many names for the Milky Way. The Yolnu people of Arnhem Land in Australia’s Northern Territory refer to the Milky Way as Milnguya, the sky river. One of the prominent patterns in this image is associated with the contrast between the light and dark regions of the Milky Way. These dark regions are cool dense clouds of interstellar dust and gas, which block the light from stars behind them. One of the prominent patterns is that of the Celestial Emu referred to as Tchingal by several Indigenous peoples of south Australia. The head and beak of the emu (the Coalsack Nebula) lie to the bottom-left of the Southern Cross (seen in the far bottom-right of the image), and the body and legs stretch leftward from it. Other indigenous groups associate the dark regions with caves or waterways. The orientation of the emu over the year provides important clues as to when it is time to pick emu eggs, and when the eggs are hatching. In some months, when these clouds of the Milky Way are close to the horizon, they are not considered as emu at all but as two creeping crocodiles. The modern figure of the dark Pipe Nebula is clearly visible above the centre of the Galaxy; the smoke of this pipe reaches the colourful rho Ophiuchi region next to Antares in Scorpius, the orange-red star just above the Milky Way. Antares is referred to by the Boorong people as Djuit, the red-rumped parrot, while the Kokatha people of the Western Desert refer to Antares as Kogolongo, the red-tailed black cockatoo. In addition, some notable constellations can be seen: Cygnus, Aquila, Lyra, Scorpius, Sagittarius, Crux, and Centaurus. The pointer stars, Alpha and Beta Centauri, are occasionally interpreted as The Eyes of the Beast in some South African traditions.

Caption: Winner in the 2022 IAU OAE Astrophotography Contest, category Still images of celestial patterns.   This all-sky image shows our home galaxy, the Milky Way, crossing the zenith, the point just above the observer as seen from Nagano, Japan, in May 2019. Such images of the whole sky can be taken either with a fish-eye lens or with a convex mirror on the ground, the latter of which would show the photographer as well. Some of the brightest stars in the night sky can be seen in this image, as well as two of the giant planets of our Solar System: Jupiter, the brightest point in the bottom of this image, and Saturn, another bright point just to the opposite side of the Galaxy, to the bottom and next to the horizon. Directly right of the Milky Way and below Jupiter, we can spot the bright red star Antares, the primary star of the Japanese asterism of The Heart. Japanese constellations derive from ancient Chinese constellations, which were adopted with only slight or no changes. In this tradition, The Heart is the heart of the “Azure Dragon”, a super-constellation that represents the spring. In the Babylonian and Greco-Roman traditions, this area is considered the heart of the Scorpion. In Babylonian religion, the star is associated with Lisi, the child of the mother goddess, but in Greek mythology it is related to the planet Mars, because of its colour. The reddish colour also led to the star’s Chinese name “The Fire Star”. We know that this colour is caused by its relatively cool temperature. Going from Antares to the right of the image, we find the more northern parts of the sky. The bright star in the lower-right of the image, close to the horizon, is Arcturus, located in the modern constellation Boötes. While Antares and its surrounding area are considered the heart of the Azure Dragon, Arcturus and Spica (below the horizon) are two single-star asterisms forming its huge horn. Pointing towards it from above, at the right-hand edge of the image’s horizon, we can see the handle of the Big Dipper, or Plough, which is part of the constellation Ursa Major. The bright point to the right of the galaxy and just above the middle of the image is Vega, located in the modern constellation Lyra. Extending a line to the other side of the Galaxy and a bit lower in the image we can find Altair, in the constellation Aquila. From that point we extend another line to Deneb, the brightest star in the constellation of the Swan, also a bit higher in this image and completely flooded by the Milky Way. These three bright stars comprise the asterism known as the Summer Triangle in the northern hemisphere.

Caption: Honourable mention in the 2022 IAU OAE Astrophotography Contest, category Still images of celestial patterns.   This image was taken in Tisma, Nicaragua, in April 2022 during a night illuminated by the Moon. Still, some constellations are visible, but the Milky Way, which runs through the image with some of its brightest regions, hides in the celestial background, partially obscured by terrestrial clouds. The Scorpion, one of the constellations of the Zodiac, is seen on the left side. We can first spot the brightest star, Antares, in the middle of a group of three in an asterism that looks like the stem of a flower growing from the clouds upwards. Its petals are the head of the scorpion. In the brightness of moonlight, the orange colour of Antares is not clearly visible. The three stars that comprise the head of the scorpion are called Acrab, Dschubba and Fang. They were recently named by the IAU in order to show the global diversity of constellations. Acrab is the Arabic term for the scorpion and Fang (The Room) is the name of the Chinese constellation made out of these stars. The Scorpion’s tail extends to the bottom of the image with the sting just above the horizon in the gap between clouds. The constellation Centaurus is visible in the middle of this image. We can first recognise Crux and the two pointer stars, Alpha and Beta Centauri right above the clouds. The pointers are the front hooves of the centaur, while the stars of Crux were originally (before Christanity, in antiquity) considered one of the rear legs of the centaur. The stars in the front hooves are Rigil Kentaurus (mixed Arabic and Latin meaning The Foot of the Centaur), to the left, and Hadar, to the right. With Crux at the rear they comprise the legs of the mythological creature’s horse body. The humanoid torso is represented by two bright stars on the shoulders and three fainter stars for the head. The star tale says that this figure represents Chiron, the only decent one among the centaurs who was well educated and the teacher of all great heroes. The Christian navigators who sailed to the New World around 1500 used these asterisms, although they had never seen them before in Europe. These included explorer Amerigo Vespucci whose name was given to the continent America. His shipmate Andrea Corsali, who came from Florence, where the poet Dante Alighieri was famous for his Divine Comedy written two centuries earlier, was reminded of Dante's poem by the four bright stars of Crux. It was probably in this context that they happened to invent the constellation Crux. Originally, the navigators only used the asterism for practical purposes but some time later, in the period of Christian religious wars between several new churches, celestial cartographers used the cross as a symbol of unity and against war.

Caption: Honourable mention in the 2022 IAU OAE Astrophotography Contest, category Still images of celestial patterns.   Taken in May 2022 in Teide National Park in Tenerife, Spain, this image shows the arc of the Milky Way galaxy crossing the sky, accompanied by prominent constellations over the professional telescopes located on the mountains of that island. While the telescopes and the people working with them may  ignore the constellations, the photographer managed to catch the Milky Way in such a way that it almost matches the shape of the mountain. The bright star in the top-left side of the image is Vega, one of the brightest stars in the night sky and located in the small constellation Lyra. Being a white star, it is the standard star astrophysicists use to define the colour scale. As it is also a relatively close star, only about 25 light-years away, with a relatively simple name, it frequently appears in modern science fiction, for example in Carl Sagan’s famous novel “Contact”, which was filmed in 1997 with Jodie Foster starring as a radio astronomer. The bright star seen below the galaxy and on the left half of the image is Altair, also one of the brightest stars in the night sky and located in the constellation Aquila. Together with Deneb — a star in the constellation Cygnus (the Swan) that is not visible in this image — Altair and Vega form the Summer Triangle, a characteristic asterism of popular astronomy in the northern hemisphere, where these telescopes are located. On the right side of the image we can see the constellation Scorpius. This is easily identified by its brightest star, Antares, the reddish star in the Scorpion’s heart. Below it, the whole body and tail of the Scorpion can be found and above it the celestial Scorpion's head is represented by three bright bluish stars. Below the tail and above the horizon, the constellation of Ara, the Altar, is half-visible, but like all the stars of Sagittarius in the Milky Way and the much fainter ones in Hercules and Ophiuchus above it, these constellations are more difficult to pinpoint in this photograph full of stars. The head of Ophiuchus is the relatively bright star in the middle between Vega and Antares. In addition to the huge size of this constellation, it is also important because it is the thirteenth one of the Zodiac, and the Sun spends roughly three weeks in Ophiuchus, after only five days in Scorpius. Furthermore, Ophiuchus represents the model for the mythological best doctor in the world, called Asklepios in Greek mythology, and Aesculab in Latin. His constellation praises all people working in medical professions, including nurses, pharmacists and doctors.

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: Winner in the 2022 IAU OAE Astrophotography Contest, category Still images of celestial patterns. This image composition is amazing. In the far background of the landscape we see a chain of mountains that seems to mirror the structure of the Milky Way in the sky above. The strong daylight-like colours of the landscape are caused by the Moon, the bright light at the top of the image. Taken in Kinabalu, Malaysia, in February 2019, this image shows the alignment of planets and the Moon, conveying the idea of the ecliptic as the central line of the Zodiac, the plane within which all planets orbit the Sun. The ecliptic is the central line of the Zodiac, so the region of about five to 10 degrees either side of the ecliptic is where the constellations of the Zodiac are located. Starting from the horizon towards the bottom left of the image we can see the planets Venus, Saturn and Jupiter. The planets have different cultural significance for people around the world, and are deeply embedded in social, religious and practical aspects of life. For example, Wardaman traditions of Indigenous Australians associate the planets with ancestor spirits who traverse the Celestial Road (ecliptic). The appearance and disappearance of planets in the sky are associated with various ceremonies. For example, when Venus starts being the “Morning star” after having been the “Evening star”, this marks the Banumbirr ceremony for the Yolnu people of Arnhem Land, in Australia. The image also shows the constellations Scorpius, Aquila, Lupus and Triangulum Australe, the asterism of the Teapot, and the two pointer stars Alpha and Beta Centauri. The constellations, asterisms and individual stars within them have significance in many different cultures. Malaysia, being close to the equator, has had connections to the north as well as to the south and almost the whole sky is visible over the course of the year. The star Antares is seen by the Kokatha people of the Western Desert as Kogolongo, the red tailed black cockatoo, while the Boorong refer to it as Djuit, the red-rumped parrot. The two stars which form the stinger of Scorpius (Shaula and Lesath), are called Karik Karik, the Australian Kestrel.

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.

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.

Caption: Winner in the 2022 IAU OAE Astrophotography Contest, category Still images of celestial patterns.   The Milky Way and several astronomical objects are seen in this image taken from the southern hemisphere, in Anglers Reach, Australia, in April 2022. On the bottom-left side we can identify the constellation Scorpius with its brightest star, Antares, the reddish spot just above the arc. Some prominent but small southern constellations can also be seen: the dominating bright stars in the middle-left of the image in the Milky Way are the four bright stars of Crux (the Southern Cross) and to its left the two pointer stars, alpha and beta Centauri. Crux points towards the southern celestial pole, which is not marked by a bright star, and The pointer stars point towards Crux, distinguishing it from the asterism of the False Cross in the constellation Argo. Crux features on the national flags of Australia, Brazil, Papua New Guinea, Samoa and New Zealand. As Crux lies in the brightest parts of the Milky Way, the dark cloud of the famous Coalsack Nebula is prominent next to the bright stars. It forms one of the dark constellations in South American, South African and Australian indigenous cultures. The huge Australian dark constellation of the Emu is almost completely above the horizon in this image, stretching from its head in the Coal Sack to the horizon. In Greek antiquity, the stars of Crux also belonged to the constellation Centaurus, a hybrid creature with a human torso and head attached to a horse body with four legs. The Greek centaur represents Chiron, the wise teacher of all Greek heroes. Its brightest star is Rigil Kentaurus (Alpha Centauri), the front hoof of the centaur. Just below it, we find the small constellation Triangulum Australe. The triple star system of Alpha Centauri is our Sun’s nearest stellar neighbour. Along the Milky Way in the middle-right of the picture we find the huge constellation Argo, the Ship. The smaller ancient constellation Argo was extended by Dutch navigators around 1600, and the number of stars in this constellation was then so big that the 18th-century French mathematician Lacaille needed to introduce subtitles for Argo in his star catalogue. In doing so, he invented the constellations Puppis, Carina and Vela. In Carina, the Keel of the ship, this reddish photograph clearly displays the Carina Nebula. At the right edge of the image we can spot the brightest star in the night sky, Sirius, while the second brightest star, Canopus, the rudder of Argo, the Ship, dominates the area under the arch of the Milky Way. Also below the Milky Way arc, we can see the Large Magellanic Cloud and the Small Magellanic Cloud, which are small satellite galaxies of our own Galaxy.

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.

Libra is surrounded by (going clockwise from the top) Serpens Caput, Virgo, Hydra, Centaurus, Lupus, Scorpius and Ophiuchus. Libra 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 Libra from late October to late November. The other planets of the Solar System can often be found in Libra. Libra lies just south of the celestial equator and is thus visible at some time in all but the most arctic regions. Libra is most visible in the evenings in the northern hemisphere late spring/early summer and southern hemisphere late autumn/early winter. 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.

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 lines joining the stars appear on the sky.

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.

Caption: The constellation Ara along with its bright stars and surrounding constellations. Ara is surrounded by (going clockwise from the top): Scorpius, Norma, Triangulum Australe, Apus, Pavo, Telescopium and Corona Australis. Ara is a southern constellation that is visible from the entire southern hemisphere at some point in the year and is visible from equatorial with parts of the constellation visible from some temperate parts of the northern hemisphere. It is best viewed in the evening in the northern hemisphere summer and southern hemisphere winter. The globular clusters NGC 6352 and NGC 6397 lie in Ara. These are marked here with yellow circles with plus symbols superimposed on them. The open cluster NGC 6193 also lies in Ara, this is marked here with a yellow circle that is partially obscured by the dot marking the brightest member of the cluster which is visible to the naked eye under good conditions. 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.

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. 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.
