Explanation: What's happening near the center of this cluster of galaxies?
At first glance, it appears that several strangely elongated galaxies and fully five bright quasars exist there.
In reality, an entire cluster of galaxies is acting as a gigantic gravitational lens that distorts and multiply-images bright objects that occur far in the distance.
The five bright white points near the cluster center are actually images of a single distant quasar.
>Close inspection of the above image will reveal that the arced galaxies at 2 and 4 o'clock are actually gravitationally lensed images of the same galaxy.
A third image of that galaxy can be found at about 10 o'clock from the cluster center.
