A roughly spherical bubble of hydrogen gas, the Gum Nebula contains a volume of space larger than the entirety of the United Federation of Planets and its neighboring powers combined. This region of space was first reached by the USS Excelsior and the USS Olympia (24th century) on Beta Quadrant survey missions. Comprehensive exploration commenced in 2379, when Starfleet assigned two of their new Luna class vessels, the USS Titan and the USS Ganymede, to blaze trails into the unknown space.
The Titan began her explorations in the coreward half of the nebula, while Ganymede started in the rimward half.
Early in her explorations, the crew of Titan discovered that the Gum Nebula was home to many of the Milky Way Galaxy's cosmozoan species such as the Star-jellies and the Branchers, among others. (TTN novel: Orion's Hounds)
