Enormous 3000 Miles Wide UFO Disc Filmed From International Space Station

The gigantic 3000-mile disc was captured in an image posted by NASA. The mysterious object was flying over the Earth and nobody can find an explanation to it. The image belongs to the ISS and was first presented at the Brasilia Planetarium Presentation in 2013. The question seems obvious. What is the object that we can see in the picture?

Could it be an alien mother-ship? Could it be an interdimensional or intergalactic space-gate? Or even a planetary defense shield? The truth is that nobody really knows what that object could be. However, it is not the first time that strange and mysterious objects are sighted flying around the Earth.

Could this be related to the famous interstellar object discovered a few years ago called Oumuamua? It is quite shocking that such a huge object has been discovered right above our heads and nobody noticed it. What do you think?
