RXJ1242-11
RXJ1242-11 is an elliptical galaxy located approximately 200 megaparsecs (about 650 million light-years) from Earth. According to current interpretations of X-ray observations made by the Chandra X-ray Observatory and XMM-Newton, the centre of this galaxy is a 100 million solar mass supermassive black hole which was observed to have tidally disrupted a star. The discovery is widely considered to be the first strong evidence of a supermassive black hole ripping apart a star and consuming a portion of it.〔NASA: ("Giant Black Hole Rips Apart Unlucky Star" )〕 ==References==
