I think I know, but it involves Raid spoilers. (Destiny)

While waiting in the explorable area past the Iron Temple for Beorn's internet connections to "git good", Xenos and I wondered about this strange structure on the boarder of the Plaguelands:

It is far more massive than even the Cosmodrome wall. It's just beyond the main lake that the Plaguelands encircle. And it appears to have a large central ball and multiple panels or wings that end in long, spindly structures...

Does anyone know what this strange thing is? Any guesses?

WotM spoilers incoming.

Just after you escape the death zambonie and make the jump down to the ledge below, you approach a large structure and head underground for the final section of the raid. I believe the structure in your screenshot above is that same structure. Just before you enter it, you can look across the water and clearly see the Plaguelands and the archon's forge.
