Is there a black hole at the center of every galaxy?

The star that orbits the black hole in the centre of the Milky Way orbits once every fifteen years (this is really short) and we've been (incredibly) able to watch it move around the black hole. It comes within a light-day of the event horizon, and that's still not close enough to get torn apart or sucked in. read more

At the heart of virtually every large galaxy lurks a supermassive black hole with a mass of a million to more than a billion times our Sun. Most of these black holes are dormant, but a few per cent are ‘active’ meaning that they are drawing material from their host galaxy inwards, This forms an accretion disc that feeds the black hole. read more
