Of course not. Just pointing out what appears obvious to me. If it is an plasma, it has to move through a medium. Space is the lack of a medium. In a true vacuume a plasma could not exist. The medium the supposed Ion tail appears to be moving through can not exist as a straight line moving mass. It can only be there if it is completely surrounding the comet in 360 degrees and on all axis. Then and only then can it be either an electrical show phosphorescing in the darkness of the tail, or a light show caused by refraction of coma reflection. (remember the street lights with the show they put on in the shadow above them?) Whatever that medium is, it can not move at the speed it appears to move either latterally to or in line with the solar winds. In another analogy, think of the beam of light coming from a light house. If the air is clear, you do not see the beam as it swings around in a 360 degree circle unless you look directly at the light. But if there is a slight haze in the air you can see the beam of light and it appears to move through the air, fairly slowly near to the light house and much faster at a long distance from the light house. Now try to imagine a situation in which there is no mist in the air except in the beam of light and it is able to move laterally with the beam. That is what you are expected to believe is happening in the so called Ion tail of a comet under the accepted theories. It is like thinking the mist is being shot from the lighthouse at the speed of light. Quantum Physics, gravitaional and orbital physics all say that it is not possible.

Whatever it is, it sure is pretty though and breath takingly amazing to watch.

Thanks for the photo.
