It is now thought that most galaxies host supermassive black holes at their centers. In fact, 25,000 light years away at the centre of our own Milky way Galaxy is a black hole with 4 million times the mass of our own sun. It is this supermassive black hole that is the main target of investigation of BlackHoleCam and Event Horizon Telescope projects.
