In 2366, the  used it to hide from a pursuing Borg cube. The Enterprise had to slow to impulse to enter it. Once inside, the nebula became too dense to go farther using impulse. The composition of the nebula cloud was determined to be 82% dilithium hydroxyls, magnesium, and chromium and found to be effective in screening the Enterprise from the sensors of the Borg, so the Enterprise continued on into this denser spiral cloud section of the nebula. The Borg did not follow them in but continued to scan for them and adapt to the situation.
