Messier 22
Two black holes of between 10 and 20 solar masses each were unearthed with the Very Large Array radio telescope in New Mexico and corroborated by the Chandra X-ray telescope in 2012 . These imply that gravitational ejection of black holes from clusters is not as efficient as was previously thought , and leads to estimates of a total 5 to 100 black holes within M22 .
