Most likely cause is that you have different versions of some mod between client and server. (I assume you are playing on a server.)
Anyhow it's not Galacticraft per se (or Extra Planets or Optifine) causing this.
If your mods and configs are exactly the same between client and server (apart from client-only mods like Optifine) then we can start to look for some other cause. Possibly it could be a mod which affects other mod's mobs - I don't know what all your mods do.
By the way, respect for using the SpaceX mod!
