That's no moon, that's a...

More proof that if you look into space long enough, you're bound to spot something interesting. A NASA/U.S. Navy mission to keep tabs on the Sun's solar flares (using satellites called STEREO A and B) took this video:

Hmmmm. (to see the original, not-so-X-Filed version, go here)

As Gizmodo puts it,

The video shows a coronal mass ejection coming from the Sun and reaching the planet Mercury. Coronal mass ejections are massive explosions of solar wind, radiation and magnetic fields that go well beyond the solar corona, deep into space. They are so big that sometimes they reach Earth.

You can see the gigantic solar wave reaching Mercury but, just as it goes through, something else becomes visible: a very angular shape that seems to be formed by two separate objects joined together. It looks as if the CME wave reveals a volume on impact, interacting with it.

You know, like a cloaked Klingon Bird of Prey being uncovered by the Sun's radioactive fury.

So, digital artifact or planet-sized spaceship? I know which one I want the answer to be. Perhaps it came from our newly discovered sister planet....
