If its an alien ship why is it throwing out a "comet tail" like that?

This might help explain the reason why we see what we see...

And then again it might not be a good enough explanation for some...

Since we’re following ISON, it’s the stars that appear to move. In each exposure that’s been added into the above image, stars are in a different position. From frame to frame, they move like the comet moves in the GIF. Moreover, the images of single stars are smeared out instead of round. Even during the short individual exposures, stars are visibly drifting relative to comet ISON.

I think you were doing fine with your reasoning up to this point. Remember that a lot of comets are potato shaped and tumble along as the move. If there are three points of light, or ‘jets’, tumbling along with the comet then we might get a shape like that. Also remember that this ‘V’ or boomerang shape is a product of several stacked images that are not tracking the comet and a darkening software program so what we see is not what is really there.
So if we take the motion of the camera, Hubble, through space in its path with Earth, the motion of the comet in its path around the Sun and the comet’s tumbling motion it is possible that we could get this odd ‘V’ shape.
Astronomers call the effect parallax -- it’s what happens when you hold your thumb in front of your face and blink back and forth from eye to eye. Closer objects (your thumb, ISON) shift when your perspective changes, much more than objects farther away like the stars do. So if you find ISON’s movement in the GIF confusing, rest assured: it’s not ISON. It’s us.
No it does not,
