The Sombrero Galaxy, viewed by the Hubble Space Telescope in This spiral galaxy, with its halo of stars also hides a super-massive black hole containing as much matter as a billion Suns. Image: NASA and the Hubble Heritage Team.
This image shows how, when viewed 'edge on ' that its then seen that galaxies are orbiting their central black hole in a very narrow, but gargantuan sized colony, the width governed by the size of its central power source super massive black hole ( the larger the galaxy / the more massive the power output of the central black hole !! ) ✅
