This. It's like I'm pointing at various things in a room, and there's someone running around with a big "This One?" sign that they keep moving in front of my object of interest. Workaround: point at one thing while looking at another.
Does someone know why the Webb telescope give this strange "sharp glare" on many of the shiny star-shaped objects ?
Is it some sort of AI upscaling or is it raw data coming from the sensors ?
Those are diffraction spikes. They are caused by the segmented mirrors and struts. Even the Hubble telescope has them just a different shape. The spikes are more noticeable on brighter point like objects like stars.
Forms of lights and our capture of it creates our “vision”.
The longer the distance it took the light to travel from the objects to our telescope, the more time it takes. By the time it is finally captured, we are watching an outdated light!
There's also the hypothesis of angular diameter turnaround: that at a sufficient distance, more distant objects would appear larger rather than smaller, because they subsumed a larger fraction of the universe at the time.
This has not been observed by JWST so far as I'm aware.
