In regard to the four blue dots at the top center forming a straight line. Is such straightness something common in nature?

Good question - such things always look surprising, but I'd want to compare with a lot of sets of four blue galaxies before concluding too much. It could be a chance alignment, or it could be that those 4 blobs are physically connected in some way, perhaps falling together under gravity, or temporarily flying apart before returning and merging together. Definitely not a lens though! 😉
