In 2008, evidence emerged of a possible intermediate-mass black hole (IMBH) at the center of the globular cluster Omega Centauri (ω Cen), 17,700 light-years away. Observations from the Hubble Space Telescope (HST) and Gemini Observatory revealed that stars closer to the center of the cluster move faster than stars further away, with seven of them capable of reaching the cluster's escape velocity. This could be explained as a black hole of up to 8,200 solar masses. In 2024, analysis of more than 500 HST images by an international team brought compelling new evidences for the likely existence of the IMBH in the center of ω Cen.
