Okay so I did some thinking, some real, long, hard, smart, big brain thinking. And this is what I think these images are.
-
(The june 4th one): I have 2 theories for this. I think this could be a gateway to every planet or space thing. Maybe these are all connecting paths, I think the bright lines are just walkways. Theory two is that these are actually just those stage light thingy or are a new item like a beacon or something. In the middle you can see something (Shaped as a building sorta and is colorful) so i'm guessing that what we're seeing is an entrance point to every galaxy.
-
(The one with a hand and another guy in frame): I have no idea what this could be since if you look it's just flat land. But one thing is can see is mountains, if you turn the image sideways you can see mountain esc shaped things to i'm guessing each planet will have its own respective biome as well.
3.(The two pictures that have one hand out): I quite literally have no idea, all I can make from this is some sort of terrain, to me also looking kind of winter-ish. Let me hear your ideas.
Other notes: Green and Red and are really prominent colors for some reason, in all 4 photos I can see reds and greens
