Check out what happened in my previously posted Black Hole System after i launched a few dozen Rigel's into it, then right clicked on the grown black hole and pressed the black hole button to lower its radius down to the proper size.
Now, bug or not, this looks pretty cool XD
Also i just noticed as i alt-tabbed back into the sim, that glow just begun to fade away
I guess it could have been the trails or something as they usually get uber bright if objects reach very high speeds (an effect which i like).
