... 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. ...

M95 is another example of a barred spiral. In fact, its overall appearance is quite similar to M91 except that M95 has more pronounced spiral structure. M95 is a good example of the kind of galaxy with a large range of intrinsic surface brightness. The large dynamic range of the CCD can capture all of this but the human eye or film will be dominated entirely by its bright center.
