 The X-ray image revealed how the black hole at the heart of the galaxy 1 was firing unimaginable amounts of radiation into surrounding space and with extraordinary consequences. 


 
We could see what was going on at the centre and we could start to understand how the black hole was feeding energy out into all the surrounding gas. 
 
What the image had captured was the mechanism 2 by which a feeding black hole can dominate everything around it. 
 
What it is doing is blowing bubbles at the centre of the cluster. And those bubbles are then expanding and growing like a pair of bubbles that might be formed in a fish tank aerator 3
 
The dark areas in the image represent bubbles of super-heated gas, showing how the black hole blasts away matter from the centre, with each bubble almost the size of our own Milky 4 Way, It is doing so across extraordinary distances. 
 
So this is showing the scale, we've seen the black hole at the centre having a galaxy wide effect on the surroundings. It's obvious in this image. I don't need to tell you anymore, because you could see it. 
 
What the image points to is an explanation for the strange correlation 5 between the mass of a black hole and the mass of its surrounding galaxy.
