Well, not sure what you expect? A Kraken ready to eat your ship in every other system?
After all, our ships are incredibly sturdy - they can stay in the corona of the most hot stars and survive and not even black holes pose any threat.
The only dangerous things out there happens if you drop in the cone of a neutron or a white-dwarf.
Or if you boost in a NSP and suddenly collide with a native - and your ship is not that strong on the shields because "what can possibly go wrong?"
Or you fail to notice the planet you are trying to land is not 0.3G but the full 3.0G then you litter the surface with debris.
IMO, exploration is not about risks, but about common sense - keeping cool, paying attention to details and finding anomalies, things that are beautifully different, strange orbits, strange bodies, close binaries and so on.
Until now we had 400 bn systems and many more landable planets.
Odyssey will increase that big number many times more depending on how many new bodies types will get landable...
No, What I expect is O/B/WR stars to be actually dangerous from their immense power output for a ship flying nearby.
I would expect WR stars to damage your shields, then hull even in SC from the intense solar winds and UV output.
I would expect small BH to damage my internals when flying close to them from the tidal forces.
Magnetars should create all matter of havoc with your ships systems
And so on.
I fully get that exploration is all about paying attention to details and finding anomalies and so on (This is what I explore for).
However the way we do that is mostly... boring.
IMO exploration should be about managing risks and paying attention to details and anomalies in equal parts.
Let me ask you : when doing exploration, do you fell more like :
A: Hacking trough a dangerous jungle searching for new species and lost civilisations or
B: Driving in the english countryside looking at the fields, farms and coastline. Safe and comfy.
Nothing is wrong with B, but ED exploration could use a lot more of A.
