8-677: The wavelength of the X-Rays show two ring-like structures of hot gas in M89's nucleus, suggesting an outburst there 1 to 2 million years ago as well as ram-pressure stripping acting on the galaxy as it moves through Virgo's intracluster medium . The supermassive black hole at the core has a mass of (4.8 ± 0.8) × 10 M ☉ . M89 also has a large array of globular clusters . A 2006 survey estimates that there are 2,000 ± 700 of these within 25 ′ . This compares to 150 to 200 of these thought (among which many proven) to surround
12-696: The possibility that M89 may be nearly perfectly spherical . Distinct flattening as ellipsoids is found in all easily measurable comparators up to a few times of its distance. The alternative explanation is that it is an ellipsoid oriented so that it appears spherical to an observer on Earth . The galaxy features a surrounding structure of gas and dust, extending up to 150,000 light-years and jets of heated particles up to two-thirds of that. This indicates that it may have once been an active quasar or radio galaxy . M89 has an extensive and complex system of surrounding shells and plumes, indicating that it has seen one or several notable mergers . Chandra studies in
