Summary

Constellations: Patterns of Stars in the Sky

  • Constellations are areas on the celestial sphere where a group of visible stars forms a pattern representing an animal, mythological subject, or inanimate object.

  • The origins of constellations date back to prehistory, and different cultures and countries adopted their own constellations over time.

  • Twelve (or thirteen) ancient constellations belong to the zodiac, which the Sun, Moon, and planets all traverse.

  • The International Astronomical Union (IAU) formally accepted the modern list of 88 constellations in 1922.

  • Any given point in a celestial coordinate system lies in one of the modern constellations, and the Flamsteed designation of a star consists of a number and the genitive form of the constellation's name.

  • Asterisms, or star patterns or groups, are not constellations under the formal definition but are also used by observers to navigate the night sky.

  • The oldest Babylonian catalogues of stars and constellations date back to the beginning of the Middle Bronze Age, and the Greeks adopted the Babylonian constellations in the 4th century BC.

  • Today, there are 88 IAU-designated constellations, and a constellation or star that never sets below the horizon when viewed from a particular latitude on Earth is termed circumpolar.

  • Stars in constellations can appear near each other in the sky, but they usually lie at a variety of distances away from the Earth.

  • The southern constellations are more modern than the northern constellations, and different groupings and different names were proposed by various observers.

  • Southern constellations were important from the 14th to 16th centuries, when sailors used the stars for celestial navigation.

  • Several modern proposals for constellations have not survived, and the French astronomers Pierre Lemonnier and Joseph Lalande, for example, proposed many constellations that did not become widely recognized.

  • The history of constellations is imaginative, and the constellations of the northern and southern skies have distinctly different origins.Modern Constellations and Dark Cloud Constellations

  • Quadrans Muralis was a northern constellation that survived into the 19th century, but is now divided between Bo├Âtes and Draco.

  • The International Astronomical Union produced a list of 88 constellations in 1922, which is based on the traditional Greek constellations listed by Ptolemy in his Almagest in the 2nd century and Aratus' work Phenomena.

  • The aim of the 88 constellations is area-mapping, i.e. the division of the celestial sphere into contiguous fields.

  • The 88 constellations are divided into 36 northern and 52 southern constellations.

  • The boundaries of the 88 constellations were developed by Eugene Delporte using data that originated back to epoch B1875.0.

  • The constellations have no official symbols, though those of the ecliptic may take the signs of the zodiac.

  • The Great Rift, a series of dark patches in the Milky Way, is more visible and striking in the southern hemisphere than in the northern.

  • Dark cloud constellations are patches of dark nebulae in the Milky Way that have been given names by various cultures.

  • Members of the Inca civilization identified various dark areas or dark nebulae in the Milky Way as animals and associated their appearance with the seasonal rains.

  • Australian Aboriginal astronomy describes dark cloud constellations, the most famous being the "emu in the sky" whose head is formed by the Coalsack.

  • The article provides a list of further reading material for mythology, lore, history, archaeoastronomy, atlases, celestial maps, and catalogs.

  • The article also provides a list of external links for further exploration.
