The cluster CL2244-02 above is composed of many yellow galaxies and is lensing the image of a very distant blue-white background galaxy into a huge arc.

Human beings from the Blue Galaxy were precisely those who came in marvelous ships that had the shape of red fish.

If you look closely, you can see a stream of material being sucked from the blue galaxy into the black hole.

The singular form of the galaxy blue background (center of the cluster), allowed to infer that the same galaxy as we see on this image to 4 hours, 10 hours, 11 hours and 12 hours.
