I will proceed with a controversial theory.
The energized structure is not the Ark.
In the second page of Conversations of the Universe, an excavation on Coral revealed a Forerunner structure unlike any of the Halo rings. I believe that is the Ark. Furthermore, the glowing ring in the center of the structure closely resembles the Marathon symbol.
