The Typhon Expanse was a region of space which, as of 2368, had yet to be explored by any Starfleet vessel.

In that year, the starship Enterprise embarked on an exploratory mission in this sector, when it encountered a temporal distortion from which the USS Bozeman emerged, having been transported through time from the year 2278. Colliding with the Bozeman, the Enterprise was subsequently destroyed, and the resultant explosion, being in such close proximity to the distortion, ruptured the spacetime continuum. As a result, both ships became trapped in a temporal causality loop in which the Enterprise repeatedly encountered the Bozeman and was destroyed. Eventually, the Enterprise crew was able to determine the nature of the loop and avoid colliding with the Bozeman, thereby freeing both vessels from the loop. (TNG: "Cause and Effect")
