What do you do in hidden systems such as the Ta system? It seems just like infinite spawning pirates. How do I get the artifacts in them?

If its a pirate inhabited system you simply wipe out the 3-4 waves of pirates and then you automatically get the artifact as well as a bounty for liberating the system. If it's just a regular system with an artifact you could go to the asteroid, but after doing it about 10 times it gets long and repetitive. Simply go to the trade station, click "Smuggling," and from there you can purchase the artifact for about 20-30K. In the early stages when money is tight you might save the credits, but after a few hours you should have plenty of credits to spare and it's worth paying a little to forgo the long annoying, monotonous artifact run.

Thanks for the help guys!
