The Gamma Erandi Nebula was a stellar nursery with an energy expenditure of 5.34 ×1041 watts, which, as of 2366, was fairly typical of this type of phenomenon. The nebula generated high levels of subspace static, which interfered with nearby subspace communications.
In 2366, the USS Enterprise-D conducted a study of the Gamma Erandi Nebula after attending the biennial Trade Agreements Conference on Betazed. The ambient interference prevented them from receiving a Betazoid message that William T. Riker, Deanna Troi, and Lwaxana Troi were missing until two days after the occurrence. (TNG: "Ménage à Troi")
