Good to know, thanks! One thing I love about this game, I'm learning more and more about astronomy, even as I fly about and honk and kill stuff!
Looking at the examples in the article, the three I mentioned do look far more similar to each other than those pictured; they are three blue-ish "butterfly" shapes, with a black seam down the middle, and a reddish hue at the base (which also extends around the back if you rotate around them).
But disclaimer: I'd been exploring around the galactic fringes for a few weeks so was starting to see faces on every planet I found. It's possible I have gone slightly insane.
It happens to us all eventually... being alone in the void for weeks on end does strange things to ones sensibilities... welcome to the club
