A supermassive black hole at the centre of the PDS 456 galaxy has been caught belching up gusts of gas so strong, they could halt star formation and stunt the growth of the entire galaxy.
The discovery was made by an international team of astronomers that used the European Space Agency’s (ESA) XMM-Newton telescope, and NASA’s NuSTAR telescope, to watch the activity of this colossal cosmic object that lies two billion light-years away from Earth, and boasts a mass of no less than a billion Suns. For comparison, the black hole at the centre of our Milky Way galaxy has ‘just’ 4.3 million times the mass of the Sun.
