Is this a galaxy cluster?

It looks like galaxies are coming together in a cluster. How is there so many in such a small area? If it is what would make them do that besides a massive galaxy? I have so many questions lol

These galaxies are probably well spaced out 😃 The blue one is probably closer to us that it is to the yellow ones. The orange one is quite distant.

I thought the light changed also by the direction it's moving so would it be possible if the blue one was just currently moving towards us. Im sure your right it just seems so close

Also there is a lot of galaxies in a u shape of the same color if you zoom out. Looks as if they're all going down a drain.

Maybe they aren't all close but those in that shape sure do look the same. If you get a chance to zoom out on it can you tell me what you think. Thank you by the way for answering my question

Some close galaxies have a slight blueshift, but not enough to affect their colour. Distant galaxies always have a redshift.
None seem to have a spectrum taken so no redshift z available, and I can't find a reference about galaxy cluster. They do seem to be the same colour, so maybe they are a cluster. You can check their Photoz and see if they have the same distance.
#1 How do I : Find out more information about the galaxy I have classified? https://talk.galaxyzoo.org/#/boards/BGZ0000005/discussions/DGZ0000lv2

Thank you very much for your help. I tried posting that picture but couldn't figure it out.
