It's coming from Saturn:

Something burst OUT of the planet Saturn. I assume it's heading towards earth. I also assume this will be the first of the missles that will bring so much calamity to our planet...
"Deep in the outer realms of our solar system, well over a billion kilometers away, something bizarre happened at Saturn’s F ring.

I mean, seriously: what the hell happened here?

This is one of the latest pictures returned from the remarkable human achievement that is the Cassini spacecraft, a probe the size of a school bus that has been orbiting the ringed planet since 2004. It’s returned one incredible picture after another, and lately — as Saturn’s orbit has brought it to a point where the rings are nearly edge-on to the Sun — things have gotten not only spectacular but also really weird.
...
It’s not exactly clear what’s going on here, even in this slightly zoomed shot. But it looks for all the world - or worlds — like some small object on an inclined orbit has punched through Saturn’s narrow F ring, bursting out from underneath, and dragging behind it a wake of particles from the rings."
