The Enterprise at the Jonisian Nebula
The Jonisian Nebula was a planetary nebula located at coordinates 2912.7736. It had a complex structure with a core radius of 0.28 light years and a density of 1.8 ×103 cubic centimeters.
In 2259, the USS Enterprise conducted a routine survey of the Jonisian Nebula. While there, it encountered a sentient non-corporeal lifeform speculated to be a Boltzmann brain, later named Debra by Rukiya. (SNW: "The Elysian Kingdom")
This nebula was named after the daughter of scriptwriter Onitra Johnson. [1]
