Regarding the 1st picture of the ring galaxy. The bright thing in the center, is it the "main sun" of this galaxy? Is it comparable with our solar system?Super interesting @flurgx. Looking forward for more astronomy-articles from you.

The centers of galaxies are usual bright because there is a dense population of stars but we can not see a single star within another galaxies, nor is there such a thing as a main star. Astronomers say there's a black hole within the center of a galaxy.. But it could also be a white hole,.. We don't know for sure.. Maybe it's both, black and white together... We know very little about the universe and how it really works 😊
