A random event that could occur would be the formation of a time/space anomaly on the map. It would open and could be one of two directions: in or out. If it is in, it begins sucking resources/animals/items/people who get too close to it into it to be gone forever. It would last for a random amount of time or until your colonist could set off an explosion inside (without getting too close and sucked inside of course) via a grenade or other explosive device. Depending on the randomly calculated 'strength' of the anomaly it would take an equivalent number of explosive strength to close it.
If it is out, it would spew random things on to your map with various odds of occurrence. For example it could have a high chance of spewing common resources like wood/steel/cloth etc. it would have lower chances of spewing items like spaceship chunks or higher technology resources or weapons. It would have a chance to spawn animals (hostile or passive). It could spawn raiders or additional colonists. Since it is a time anomaly as well, it has a very low chance of spawning a clone of one of your deceased colonists.
I suggest it be called the 'Zoooop!' event from the noise I imagine an anomaly would make when it suddenly appears. Zooop!
