This is a Neutron and how to scoop it for 300% boost. You need a fuel scoop to do that.

Ones with bigger stars and smaller arms are white dwarves, chances are that's what you saw as there's only really 2-3 Neutrons near the bubble. "Jackson's Lighthouse" is one system over near Felicity Farseer and there's another I think 2nd star of ETA Casiope <- Checking that now, edit on the way. (Edit: Still not sure but there is a secondary star one somewhere in the bubble that Fuel Rats have used a few times.)
