With qbjs, I almost don't need QB64 installed, lol.
I commented out the _PUTIMAGE blur stuff in the qbjs version and ran it, since _SETALPHA isn't used those aren't needed. That took care of the shooting stars.

Last version probably. Orbs now each have twirling plasma colors, and I add a space portal that randomly opens and closes in the center of the screen now and then. It may be too distracting, but I like the colors better than the other versions. Not running in qbjs yet, so here's the qb64 code box...

I need to move from playing with this, but just can't without adding some user interaction first.
Press SPACE bar to break up outer space into pieces and warp away.
(Resets plasma clouds too). Shows the power of RotoZoom3!
Left click mouse button to change size & speed of plasma cloud.
Right click mouse button to change around the plasma cloud color.

@Dav that looks really sweet man. Nice orbs. Pressing space is fun. Need some sound effects of glass breaking (or in my case brain blowing up)  when that happens.
