One of my favourite ghost shells us the hissing silence shell, it's always given me vibes of "this ghost has slight eldritch madness" but I've always wondered; is the heliopause mentioned in its description an actual thing or something just to make the shell sound cool

The whole thing is an actual thing! Hissing Silence is themed for the Nine and has this description:

For Ghosts who have meditated beyond the heliopause.

It's refering to the lore about nine Ghosts that did just that as it says on the description. The name of the shell itself is a reference to this from this grimoire card from Destiny 1 that explains possible origins of the Nine:

The Nine are Ghosts who pierced the Deep Black without a ship and meditated on the hissing silence of the heliopause.

This is obviously not what the Nine are, but there were nine Ghosts that did just that and Orin found them in her search for the Nine. She had a conversation with them which you can read here. They gave her further coordinates to continue on her search. We don't know much more than that, but there's definitely an eldritch vibe going on with that.

And yes, the heliopause itself is an actual thing, if you meant just that. It's basically a boundary between the solar system and interstellar space, in simplest terms. Definitely check out more about it because it's fascinating!

Osiris has also been there and experienced a mindboggling event that to this day defies explanation. He was given the coordinates to the heliopause by Rasputin (because Ras was tracking the Black Fleet). Osiris got there, left his ship and entered.... some space ?? That does not match any description of any Pyramid ship and was largely described just through some metaphorical language. He does... something and somehow finds the seed of silver wings, and then returns to his ship with the seed which he plants on Io and it turns into the Tree we see in Season of Arrivals. Incomprehensible.
