This article may contain outdated information that is inaccurate for the current version of the game. It was last updated for 2.2.

This article is for the PC version of Stellaris only.

An anomaly is represented by survey readings that deviate from what is normal. When a science ship surveys a celestial body it may identify an anomaly that needs further investigation. Anomalies have their own tab in the Situation Log.

When the investigation of an anomaly is complete, an event will pop up that can give various bonuses, such as research points, resources on a planet, or even a special project which requires further research investment to unlock benefits. Certain Ethics occasionally have additional options.

Each surveyed celestial body has a 5% chance of spawning an anomaly, which is increased by 0.5% for every surveyed planet with no anomaly before being reset. The Leader trait meticulous.png Meticulous trait also increases the chance of finding anomalies by 10%.

Anomaly level

To investigate an anomaly, a science ship with a scientist on board must be present at the celestial body where the anomaly is located. Investigating them takes time, which is determined by the level of the scientist minus the difficulty level of the anomaly. As such, anomalies of higher levels are often best left off until a skilled scientist can study them faster.

Precursors

First League anomaly

The Precursors are long dead galactic empires predating even the fallen empires and the curators. Their ruins are scattered across the galaxy for the player to find via anomalies. Precursor anomalies grant a special project which once investigated grants a moderate amounts of Engineering Research Engineering, Physics Research Physics or Society Research Society research as well as a precursor artifact. 6 artifacts are required to reveal the location of a precursor's home system.

If every precursor anomaly has been investigated but no empire managed to collect 6 artifacts a random event can trigger every 20 years and add another precursor anomaly on one of the previously investigated planets. The time is lowered to 13.3 years for Gestalt consciousness.png Gestalt Consciousness empires.

AI empires can also sell a discovered artifact to Player empires for 1000 Energy Credits.png Energy. If the Player empire has the Civic warrior culture.png Warrior Culture civic it can threaten the AI empire to surrender it for free, the success rate depending entirely on both empires' Relative Power. Empires that hold a Protective, Friendly or Loyal attitude will offer the artifact for free instead of asking for payment. Each AI Empire will only offer an artifact once.

The Ancient Relics.png Ancient Relics DLC adds an artifact action for each precursor which unlocks a Special Project to delve into their secrets for a permanent reward. It also adds two more precursors that are discovered via 6 Archaeology Sites. The sites do no grant any rewards except the location of the next site until their home system is uncovered.

Archaeological sites

Archaeological Sites are areas where remains on ancient civilizations have been preserved relatively intact. That can be discovered on survey, generated at game start or generated by an event. A site can have 1-6 Chapters in addition to an introduction Chapter. Each Chapter has its own narrative and rewards and has to be unlocked before it becomes visible.

Chapters are unlocked via Excavation. As long as an Archaeological Site is within an empire's borders that empire can task a Science Ship to excavate the side. The duration of an Excavation is determined by the Archaeological Site's Difficulty rating and can be reduced by -25% if the Scientist on the Science Ship has the Leader trait archaeologist.png Archaeologist trait. As the Scientist goes through excavations, it will roll a dice and add modifiers to the result, with the following formula: Result = dice roll + archaeology skill + clues − difficulty. Additional events can also trigger at the end of each excavation.
