A solar observation


If I look at the eruption pictured in this news story linked above, and at the sun as a whole, I note that the eruption is at a significant angle above the ecliptic of the solar system which naturally corresponds with the equator of the sun (there is a small angular offset between the plane of the solar equator and the plane of the ecliptic of the solar system). I also note that there are rings of bright spots above and below the sun’s equator in the image.

If we look at the hubble pictures of jupiter: https://solarsystem.nasa.gov/resources/2486/hubbles-new-portrait-of-jupiter/?category=planets_jupiter

We can see that Jupiter has a narrow stable band at the equator and then several different bands at other lattitudes. In these images of Jupiter, huge turbulent bands, with massive storms, can clearly be seen at the shear interface between the stable bands.

It is unreasonable to state that Jupiter and the sun are truely analogous given the extraordinary preponderence of matter in the plasma state within the sun, and all of the extra and very strong electromagnetic influence arising from that (such as the coronal mass ejections themselves), but I do note that there is an apparent similarity between the bands of spots which appear on the image of the sun and the turbulent shear interface bands which are clearly visible on the images of Jupiter.

If there are indeed shear interface bands on the sun, and these serve as the primary source of coronal mass ejections, then, it could be a fortuitous aspect of physics that there is a stable equatorial band and that the majority of such ejections do not fire out directly on the ecliptic, which means that the planets of the solar system are generally spared from the worse effects.

Of course, this is only one image of the sun, and the apparent rings of spots could be illusory or could be resulting from temporary shear bands as opposed to the quasi-permanent shear interface bands of Jupiter.
