Omicron Theta

Omicron Theta is a planet in the Omicron Theta system, orbited by two moons.

It was the former host to an Earth colony, until it was annihilated by the Crystalline Entity in 2338.

When the Crystalline Entity attacked Omicron Theta, a distress call was sent from the planet before all life on it was eradicated.
The starship that responded arrived too late, discovering a lifeless world. However, the crew did discover a deactivated Data, and reactivated him.

This was the planet on which Dr. Noonien Soong and his wife perfected the positronic brain and successfully created a series of androids, including Data and Lore.

After the colony's destruction, it took considerable time to rebuild.
