The Brac Nebula.
The Brac Nebula is briefly seen in a short clip from the Metroid Prime Trilogy Developer's Voice featurette on the Nintendo Channel. A star cluster with a rotating digital pattern is seen in space, and a small note appears at the side labeling it the Brac Nebula. The only celestial body seen in this nebula is a blue planet, which may represent Phaaze. However, in an unused Logbook entry, Phaaze is described as being located near a small star. It is one of only three named nebulae in Metroid-related media, although it was most likely created for effect.
