Black hole of Andromeda
The long way needed to feed the black hole of Andromeda: from 6500 light years down to its door. The image shows the majestic of this galaxy with its many spiral arms filled with millions of stars. In the centre of the galaxy there is a supermassive black hole (small square in the image). A zoom up in this inset is bellow. It depicts long, narrow features circularising towards the centre. These are filaments of dust and gas which is being pulled into to the black hole. A further zoom of the zone (right image) shows the filaments targeting with precision the black hole location.
