Mysterious X object spotted by Hubble… We are not alone?

Not sure how I missed this, this object called P/2010-A2 was captured by Hubble in January 2010, Scientists have commentated that the strangeness is not just the X-shape, but the fact is appears to be traveling outside the dust halo and separate from its trail at around 11,ooo mph, which means it is exhibiting some odd non-comet behavior. Is it a celestial rock? Is it proof we are not alone? A chance glimpse of a alien spacecraft? And when did Hubble become a speed camera?
