Originally Published 2 years ago — by Space.com
Scientists have detected mysterious radio waves emanating from the heart of the 47 Tucanae globular cluster in the Milky Way, possibly originating from a medium-sized black hole, marking a potential breakthrough discovery. The signal was discovered through 450 hours of observations by the Australia Telescope Compact Array, revealing the most detailed radio image of the cluster to date. If confirmed, this would be the first-ever radio detection of a black hole within a cluster, shedding light on the existence of intermediate-mass black holes and the process of black hole growth.
