Was just watching a Brian Cox interview and had this question
Astronomers talk about the "observable universe" and imply there is stuff so far out there that light from those objects hasn't had enough time to reach us yet. When some of the first images from JWST were published there was some focus on highly red shifted galaxy that now holds the record for being the furthest away from our perspective, something like 14 billion light years away. This implies there's a 14 billion-ish lighter bubble around earth of which we can observe(?)
My question is, assuming the CMB is at the outer most edge of the universe how can we see it if it's outside our observable bubble?
Looking to travel to Fairbanks next year. Watching moon cycles but struggling to find KP predictions for 45-60 days out.
Adding 27 days to recent spikes is the only method we can think of to forecast. Is that even valid or is there a better way?
Maybe we are too aggressive or uninteresting or something. So many stars and we are alone?

I'm impressed with the amount of detail the L-extreme filter is able to pull out of this nebula. I've shot this target before but haven't been able to produce as clean an image until now. A real game changer!
