Zoom into the Moon and find the Disk - April 2013

There appears to be some sort of raised plateau or something what looks like a disk.. UFO?

Zoom into the Moon and find the Disk

Here is the link to the high resolution mosaic:

Use your mouse wheel or the + and - buttons on this incredible interactive view of the Moon to zoom in; use your mouse to let the image take you where you want to go. Click on the button in the lower right to go full screen and you’ll feel like you are in lunar orbit.
