This is to blame on solar panels. Modern ones are very black, i.e. a serious lack of light, creating a photonic imbalance that forces light upwards, where gravitational clustering creates an illusion of a burning spherical object.
If you are in doubt about this, check old photos- there’s no picture of the sun before the invention of solar panels. Same goes for paintings, although really old ones have a sort of symbolic sun-like object, which may be caused by the solar panels on visiting aliens’ starships (ref. Von Dänicken, 1968).
