Omega Research

Omega Research is a room in the Phazon Mines region of Metroid Prime.

Secret World

Jump over to the platform that has/had the bendezium on it, blocking the map room door. Just to the left of it is a scannable thing. Jump on top of that. Now turn to your right and look at the big curved pipes. Now turn to you left slightly (10 degrees) and look at the metal girders that run vertically down the room. You will see a big square that is just a bit higher than yourself. Jump to the one in the middle (there's 3, one in the middle).

Now turn to the right and face those curved pipes again. Turn to the left ever so slightly so you're facing just behind the pipes, then L-Jump to them. As soon as you 'land' you'll slide around like crazy, so morph quickly to prevent this. Now perform a DBJ. You'll get pushed onto a cement area. Turn around again so you're parallel to the map room door. Run into the abyss in front of you. You should fall straight down into the secret world. If you stop, push forward again to resume your descent.
It is also possible to do this secret world without Space Jump by doing a UBJ and a 3BJ.
