The Gamma Erandi Nebula was a stellar nursery with an energy expenditure of 5.34 ×1041 watts, which 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")
