Astronomers discover how to Feed a Black Hole

The image shows the process of nuclear feeding of a black hole in the galaxy NGC 1566, and how the dust filaments, which surround the active nucleus, are trapped and rotate in a spiral around the black hole until it swallows them. Credit: European Southern Observatory (ESO).

Researchers have discovered long narrow dust filaments which surround and feed black holes in the centers of galaxies, and which could be the natural cause of the darkening of the centers of many galaxies when their nuclear black holes are active.

The black holes at the centres of galaxies are the most mysterious objects in the Universe, not only because of the huge quantities of material within them, millions of times the mass of the Sun, but because of the incredibly dense concentration of matter in a volume no bigger than that of our Solar ...
