When you fully unlock and research all of Thar’Ga’s and possibly Tai’Kin’s nodes in hangar, you get a message displayed for a next node, listed as an Unknown node with cost info.

When you already researched all nodes, there should be no such non-existing “Unknown” nodes listed with an increased costs.
