Messier 110 (also known as 'The Edward Young Star' and NGC 205) is a dwarf elliptical galaxy that is a satellite of the Andromeda Galaxy.〔 〕 M110 contains some dust and hints of recent star formation, which is unusual for dwarf elliptical galaxies in general.〔 ==History== Although Charles Messier never included the galaxy in his famous list, it was depicted by him, together with M32, on a drawing of the Andromeda galaxy; a label on the drawing indicates that Messier first observed NGC 205 on August 10, 1773.〔 〕 The galaxy was independently discovered by Caroline Herschel on August 27, 1783; her brother William Herschel described her discovery in 1785.〔 The suggestion to assign the galaxy a Messier number was made by Kenneth Glyn Jones in 1967.〔 〕 A few novae have been detected in this galaxy. Notably one discovered in 1999 by Johnson and Modjaz,〔 〕 and another detected in 2002, by Nakano and Sumoto. The latter one, designated EQ J004015.8+414420, had also been captured in images taken by the SDSS (Sloan Digital Sky Survey) in October, 2002. Unlike M32, NGC205 does not show evidence for a supermassive black hole at its center.〔 〕 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「Messier 110」の詳細全文を読む スポンサード リンク
