You think I'm kidding? How else do you explain this picture?

That's obviously the Borg Queen. Sure, NASA says it's the crater Kertész located on the western edge of the monster Caloris basin on Mercury, but what better place to hide a Borg infestation? It's obvious as well that the small crater with the bright rays coming from it is the evidence of either some sort of transwarp experiment, or a hyperdimensional corridor leading to the Delta Quadrant. Hey, it makes as much sense as it being the Virgin Mary, or a UFO, or a crop circle.

MESSENGER betrays humanity. I knew NASA was up to something.
