Note: Unlocks after you visit Kadara Port during the quest "Hunting the Archon".
Extra-Planetary Anomaly - Starship Wreckage
In the asteroid belt closest to the star Anasa you’ll find an anomaly, a Starship Wreckage. Examine the wreckage to score some salvage.
Extra-Planetary Anomaly - Radiation Trail
Complete the quest "A Trail of Hope" and visit Kadara, after which you’ll get the Email "Please See Me", which starts the quest "Contagion". Scan the Radiation Trail anomalies in the Tecunis system and Zaubray systems, after which you’ll be able to find another Radiation Trail anomaly in the Anasa system. Examining this one is also worth 50 Milky Way Research Data points.
So close to being a golden world… if only it wasn’t for all that radiation. Oh well. Scan this planet to find a River you can examine for some XP.
