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  Meticulous trait and Map The Stars edict also increase the chance of finding anomalies by 10%.

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.

Anomaly list

Each anomaly can only be found x times where x is the number of possible outcomes. Once a certain outcome of an anomaly has occurred, the same outcome cannot happen if the anomaly is discovered again.

Heavy Readings

If an anomaly is randomly discovered on a star and the system contains a Gateway the anomaly will always be the level 2 anomaly Heavy Readings. Investigating the anomaly will issue a special project on the Gateway. Finishing the special project will grant 90-250  Physics Research and the investigating scientist will gain 2 skill levels and the  Paranoid trait.

Repeatable anomalies

There are two types of repeatable anomalies. The first is the Ancient Signs of Life anomaly, which can only be found on Barren worlds and will add the  Terraforming Candidate planet modifier once investigated.

The second are anomalies with the name randomized based on the planet class which will reveal a pre-sapient species on the planet once investigated. Such an anomaly can be triggered once for each planet class, including  Gaia and  Tomb worlds. Genocidal empires cannot discover these anomalies.

Pioneer 11

If the Sol system is present in the galaxy a random Asteroid might reveal a level 3 Debris Field Anomaly. Investigating it will discover the Pioneer 11 probe. If the empire is human it will gain 40-100  Influence. If the empire is alien on the other hand it will bring the following options:

• Decipher the data disk and gain 120-250  Engineering Research while the science ship leader gains 200 Experience. The location of the Sol system is added to the situation log. Entering the system will grant 80-175  Influence.
• Sell the data disk and gain 120-250  Engineering Research.
• Use the data disk as furniture and gain 40-100  Influence if  Xenophobe or  Fanatic Xenophobe.

Media coverage

A number of anomaly events can be solved in ways that will impact an empire's media views on the empire if not  Gestalt Consciousness. Such outcomes bring a  Happiness modifier for 10 years.

Media Coverage modifier	Happiness
Extremely Positive	+40%
Very Positive	+25%
Positive	+10%
Negative	-10%
Very Negative	-20%
Extremely Negative	-30%
