Can those be just globular clusters in their 'bright' phase? Globular clusters are not even mentioned in that article, which is weird.

I'm gonna guess that the prominent astronomers at several top-notch universities mentioned have heard of globular clusters, and that the reason it's not mentioned is it's not relevant.

Must be heck of a night sky on one of those planets

They might be too early for planets, at least rocky ones. I'm not exactly sure of the timeline for these stars, but planets require at least a generation or two of stars and novas to fuse heavy elements, and we're probably looking at some of the earliest stars formed (assuming it they are actually stars, not entirely clear yet).

Also, if they're not sure how the stars themselves can survive being so close to each other, stable planetary orbits are probably right out. :D

> Either you don't know (why reply at all?)

Because, as a lay person, I’ve heard of globular clusters, and that means several experts in the field not talking about them points not to “weird”, but to “nope”.
