I have about 78 stars and appear to be stuck. There are no new galaxies opening up but I am trying to beat the comets. Is this what I have to do to open new galaxies and get more stars? I love this game but I find the hub world unnecessarily confusing and wish that part was more linear (I understand that it is in SMG2 which will hopefully be a birthday gift for me in a couple months). I appreciate any help I can get on this.
