Sounds like the Tholian homeworld.
Facinating thing to me in the article is they have already found more than 100 planets around other stars. I grew up in a world (Earth) where they constantly debated whether ANY other stars had planets, and there were all kinds of theories about why it might be such a rare occurence.
There must be many thousands or millions of planets just in our galaxy. Imagine all the exploring to be done.
