This article covers the 88 constellations used in modern astronomy, which properly speaking are not patterns of stars, as in the common use of the word, but areas of the sky (the celestial sphere), and include the constellations of the zodiac. The ancient Sumerians, and later the Greeks (as recorded by Ptolemy), established most of the northern constellations in international use today. When explorers mapped the stars of the southern skies, European and American astronomers proposed new constellations for that region, as well as ones to fill gaps between the traditional constellations. Not all of these proposals caught on, but in 1922, the International Astronomical Union (IAU) adopted the modern list of 88 constellations.〔 After this, Eugène Joseph Delporte drew up precise boundaries for each constellation,〔(【引用サイトリンク】title=The Constellations )〕 so that every point in the sky belonged to exactly one constellation. ==History== Some constellations are no longer recognized by the International Astronomical Union, but may appear in older star charts and other references. Most notable is Argo Navis, which was one of Ptolemy's original 48 constellations. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「88 modern constellations」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
