What you see here is an example of gravitational lensing. The mass of the galaxy in the centre is so large (with both visible and dark matter) that its gravitational force is warping space itself. The blue arc you see around the galaxy is actually another galaxy behind it.This is insane. We are looking at space itself being fucked around.
