Messier 110, also known as NGC 205, is a dwarf elliptical galaxy that is a satellite of the Andromeda Galaxy.[1] M110 contains some dust and hints of recent star formation, which is unusual for dwarf elliptical galaxies in general.[1]
History
Although Charles Messier never included the galaxy in his 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.[2] The galaxy was independently discovered by Caroline Herschel on August 27, 1783; her brother William Herschel described her discovery in 1785.[2] The suggestion to assign the galaxy a Messier number was made by Kenneth Glyn Jones in 1967.[3]
A few novae have been detected in this galaxy, including one discovered in 1999 by Johnson and Modjaz,[4] and another detected in 2002, by Nakano and Sumoto. The latter, designated EQ J004015.8+414420, had also been captured in images taken by the Sloan Digital Sky Survey (SDSS) in October, 2002. [5]
Unlike M32, NGC205 does not (as of 2005) show evidence for a supermassive black hole at its center.[6]
