From UFStarfleet Wiki
The Beenobians were a humanoid race who were constantly at war with a powerful enemy species many centuries ago. Their enemies eventually won and exiled them all to the form of a gasseous nebula not far from their homeworld.
The USS Redeemer crew encountered them on a survey of the region. A diplomatic channel was established, allowing the Redeemer to successfully find a way to return the Beenobians to their original humanoid forms. (RED: Beyond the Horizon)
Recently, the Beenobians have expressed interest in becoming a Federation member-world. They were reviewed by Lt. Chase Quinnell, CO of the USS Redeemer-A. The Federation council is still considering the request for membership. No decision has been made yet.
