... Our Sun is part of a huge wheel-shaped collection of stars. ... Astronomers have long suspected it was a very massive black hole, and that every galaxy had such a central mass, created early in the history of the universe. ... However, unless that object happens to be headed directly at the black hole (a relatively small target) it will just swing around and fly away again, like a comet making a pass at the Sun. The velocity acquired in falling towards the black hole also helps it escape. ...

The most massive black holes in the nearby Universe seem to largely be hosted by massive central cluster galaxies. The ultra-massive black hole in NGC 1277, reported by van den Bosch et al. based on a stellar kinematic measurement, is an extreme outlier in this respect. NGC 1277 is not a central cluster galaxy, but a lenticular galaxy in the Perseus Cluster, at a distance of about 3.8 from the central cluster galaxy. ...
