Only one alien jumpgate I know of. Maybe you mean jumpholes?

Spoiler....







When you finish the game, the nomad systems are cut off, but there are two you can get two. There are two "Unknown Jumpholes" that you can use to find some nomads. One in Omicron Gamma and the other in Omicron Alpha.

I've come across six 'Alien jumpgates' and a Noman 'airlock'
There are other access points beyond 'the well known two' to the Noman systems -
U have access to mulitiple Nomad systems and Dyson spheres [if can stay alive long enough.
The trouble is mapping the systems - I've so far only come across two systems with names 'Omicron Major' and 'Omicron Miner'.

are you playing a modded version?

Those are part of the SP campaign. After you finish the mission when you go to them, you can never get back (unless you mod).

1.4 patch I'm not sure if you'll count that as mod, other wise no.

Might'nt this go to the Spoiler forum?

Officer! I swear to drunk I'm not God!
