Adds a few seconds of seeing the system just like if the ship was still there if the ship has been destroyed. This ability is used by the Seeker Vessel. This ability requires two Temples of Harmony to be researched.
Given the long duration of this ability and the low cost of seekers, it's entirely reasonable to simply send one to its death every ten minutes to reveal enemy planets. This is much cheaper and more effective than using options such as Clairvoyance, Eyes of the Converted, or Forewarning / Acute Premonitions. Advent has by far the most options for scouting the enemy, but perhaps unsurprisingly the scout remains the most practical throughout the course of the game.
