I started another thread rather than try to keep old ones going.
My best friend, who developed the micro shutter detectors (he discovered little wafers of silicon bent when hit by photons, and has been perfecting them for decades), says in that first photo, that everyone has seen by now, they were able to get spectra from 40 galaxies simultaneously. One has a Red Shift of 8.5, which puts it Very early in the history of the galaxy, and Very far away from us. He said everything was working perfectly.
Following is my non pro explanation of that:
That first photo covered an area of the sky about the same as a grain of sand would occupy if you held it at arms length.
Red Shift indicates how fast anything is going away from our location, and the faster it's going means it's farther away. The largest measured red shift of a galaxy seen before was a little over 11 (higher number means it's going faster). That was after a LOT of looking at galaxies all over the sky. To catch one at 8.5 in that first shot of a tiny spec of the sky foretells that there is an infinite amount of information to be found by the JWST.
