If I'm remembering correctly, you can climb the golden glowing columns, using them to edge your way around to the platform where Juno is. Go up to the stairs that plugging the second power source in revealed, then turn immediately right and use the pole to swing across the gap.
From there, it should be okay. If you get stuck, look for hanging gold columns and a gap to leap across to reach them.
