|Location:||Omicron Theta system|
This was the planet on which Dr. Noonian Soong and his wife Juliana perfected the positronic brain and successfully created a series of Soong-type androids including Data and Lore. (TNG: "Datalore", "Silicon Avatar", "Inheritance")
This Earth colony, and the planet, were devastated by the Crystalline Entity in 2338. A distress call was sent from the planet before all life on it was eradicated; the USS Tripoli was the only starship to respond but arrived too late, discovering a lifeless world. However, the Tripoli crew discovered the deactivated Soong-type android Data and reactivated him.
Along with finding the planet to be devoid of life and discovering Data, the Tripoli crew found what they believed were "dormant" plants. An analysis by an away team from the USS Enterprise-D determined that there was no soil bacteria. They also ascertained that Omicron Theta's plants were dead and not dormant. (TNG: "Datalore")
