On the right is the same star field but this time with a black hole superposed in the center of the frame. The black hole has such strong gravity that light is noticeably bent towards it - causing some very unusual visual distortion. In the distorted frame, every star in the normal frame has at least two bright images - one on each side of the black hole. ... About APOD | ...

Is the violent behavior of quasars caused by black holes in galaxies? If so, does the discovery of black holes in the centers of many normal galaxies mean that all galaxies were once quasars? ... If this is the case, then normal galaxies should still have massive black holes in their nuclei, like quasars, but these black holes should now be starved of fuel. ...

... To avoid extensive numerical calculations in the statistical simulations, we treat the continuous evolution of each binary component as a sequence of a finite number of basic evolutionary states (for example, main sequence, red (super)giant, helium (Wolf-Rayet) star,     hot WD), in which stellar parameters significantly differ from each other. ...
