There's an interesting article here on an eruption of matter from round the giant black hole in the Virgo A galaxy which, if memory serves, is about 60 million light years from our galaxy (not that far at galactic scales - about 600 "galactic diameters").
One of the lobes looks just like a slightly stooped figure with a pair of large ears, with two stumpy legs, and holding out its right arm or tentacle. Perhaps advanced aliens have mastered the technique of assembling large amounts of matter and propelling it towards a black hole so the latter ejects it in interesting shapes.
(The black hole itself is as large as our solar system, and if visible in the image below would be smaller than a pin head. So all that stuff round it is hundreds of times larger. Also, black holes don't absorb everything that heads toward them - Due to magnetic fields and high temperatures, a fair proportion is ejected away from it.)
