Gravity lens warps everything around the main gravity source into a circle, kind of like a concave lens. It allows us to see ‘around’ large wells, but the curvature evident in the photograph probably has more less obvious evidence backing up the presence of a very massive object there.
So the gravity lens is what’s warping what should be the relatively straight line of that galaxy?
Are galaxies in straight lines?
I guess? Just speculating what we’re looking at.
