American scholars and European Space Agency scholars are all saying the object is not behaving as an asteroid, not behaving as a comet, and for those Russian scientists who have been tracking it in the sky with all of their exacting calculations, have published that it changed direction and even slowed down as it crossed over Jupiter's orbital plane and later speeded up again. They say it pulses and exerts a jet at specific intervals to (they suggest) help steer it through its trajectory.

I've been following this quite eagerly and truly hope that our own agency NASA doesn't let us down here.
