1. I am skeptical that the assertion of such a discovery is truthful.

I suspect is is merely clickbait from an unreliable source.

5. Not clickbait, but not a new discovery

It's been known for a while. More info:

9. Thanks for explaining that the article is about a 2016 discovery.

I do not remember reading about the discovery when it was first reported. It is indeed interesting that there are multiple theories as to how the massive object, at a distance of almost 5 billion light years from earth, originated. One theory is that it is a supernova. From reading about supernovae years ago, I learned that, in recorded history, a few of them have shown their presence to the unaided eyes of earth observers. In our age of powerful telescopes, we are privileged with seeing displays of these types of cosmic wonders.

In a galaxy long ago and far away.
