You'll find two-fold Information about this.
- based on past evidence, there's typically (almost) nothing to be found - BUT we're still quite fresh into V3, so this is temporarily not valid and there "should" be mysterious stuff around to be found indeed
- don't expect anything though
- make the journey your goal and you'll be fine
- make "finding something new" your goal, and you may easily end up chasing ghosts or running against a 1:5.7*10E81 chance. Galaxy is darn big.
I'd recommend getting in touch with either Canonn, the Rifters or MadRaptor's Guide to Volcanism & Biologicals for example.
Be it not-yet-discovered ominous Raxxla, riddles/mysteries or finding the yet-undiscovered "tube worms" (Organics) or locating new Guardians ruins... there's always plenty of things you can sink your teeth into
