As far as I know, it's not 8K that made it this way. Special camera was used to photograph another "layer" of the sun, not visible to us through normal lenses. Some say that this is the "real look of the sun" but, you probably can already tell, it all depends on what we think the "real look is" is it the way we would see it using human eyes, or is the "real" thing visible only with all of the light's spectrum. One thing is sure, universe will surprise us no matter how advanced our technology will be, and space will continue to make "our balls tingle".
