That`s not my photo mate, I just put it up as we were talking about it. I didn`t actually have the equipment to do it back then unfortunatly. As for the direction of movement, consider this... In space there is no air which means no friction and no wind. Therefore the direction of the comet cannot possibly be ascertained by merely observing that the tail is behind, therefore the comet is moving away from the tail. The comet could just as likely be moving in the direction of it`s tail. The tail is caused by the Sun heating up the comet and causing it to lose particles, those particles move away from the Sun, in the direction of the solar wind (particles leaving the Sun at great speed and traveling across space) Imagine a globe, a globe which blows air outward in every direction with quite a bit of force. As a long haired person walks past that globe, thier hair would always point away from the globe wouldn`t it, same thing.
See what I mean? It just goes to show how vast the distances are doesn`t it, that comet was moving at insane speed yet it wasn`t visably moving at all and took ages to traverse the night sky and finally disappear. Sorry lol Get me started on astronomy or astrophysics and I`ll be talking all night ! lol
