NGC 4845 (also known asNGC 4910) is aspiral galaxy located in the constellationVirgo around 65 millionlight years away.[4] The galaxy was originally discovered byWilliam Herschel in 1786.[5] It is a member of theNGC 4753 Group of galaxies, which is a member of theVirgo II Groups, a series of galaxies andgalaxy clusters strung out from the southern edge of theVirgo Supercluster.[6]
The galaxy has asupermassive black hole, called IGR J12580+0134, at its center with amass of 300,000. In 2013, theESA observed the black hole absorbing matter from a nearby, low-mass object; possibly abrown dwarf star.[7][8] The observed X-ray flare was caught by the ESA'sINTEGRAL telescope.[9]
