翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク NGC 2683 ： ウィキペディア英語版 NGC 2683 NGC 2683 is a field spiral galaxy discovered by William Herschel on February 5, 1788. It was nicknamed the "UFO Galaxy" by the Astronaut Memorial Planetarium and Observatory.〔 〕 It is viewed nearly edge-on from Earth's location in space and is located between 16 to 25 million light-years away. It is receding from Earth at , and from the Galactic Center at .〔 The reddened light from the center of the galaxy appears yellowish due to the intervening gas and dust located within the outer arms of NGC 2683. == Characteristics == While usually considered an unbarred spiral galaxy, recent research suggests it may in fact be a barred spiral galaxy; its bar is hard to see due to its high inclination. It is also both smaller and less luminous than the Milky Way with very little neutral hydrogen〔(【引用サイトリンク】publisher= )〕 or molecular hydrogen〔 and a low luminosity in the infrared, which suggests a currently low rate of star formation. NGC 2683 is rich in globular clusters hosting about 300 of them; twice the number found in the Milky Way.〔(【引用サイトリンク】publisher=NASA-IPAC Extragalactic Database (NED) )〕 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「NGC 2683」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.
