Simple GC. Imagine looking at spinning lawn sprinkler when its stream is on the opposite side of the sprinkler from your perspective. In the case of comets, trails of paraticles extend backward in the path where the comet has come from, while other streams of particles [ions] stream away from the comet on the radial line from the sun [the solar "wind"]. Other particles stream out in all directions due to the electrical stress factor, producing the coma.

On the subject of radiation-loving extremophiles, just because a particle looks like a bacterium doesn't mean it walks and quacks like a bacterium. This is wishful thinking at best, along with the entire theory of panspermia. Hoyle and Wickramasinghe's work with and conclusions regarding interstellar organics assumed the presence of freeze-dried bacteria with a specific cystal configurations. It does not follow that if I put flour, milk and eggs in a bowl, I have pancakes.
Too many other thermodynamics defying procedures must happen before breakfast is served. This analogy of course is flawed because the complex fundamental ingredients are assumed to have preexisted.

Hi Webolife,
Thanks for the explanation but the lawn sprinkler is stationary whereas the comet is obviously rattling along. :?
I agree with you on the panspermia issue. The experts have been agreeing and then disagreeing with the theory for years. It's similar to the 'comet killed the dinosaurs' thing. :roll:

It does if you consider the coma.
The comet isn't necessarily spinning like the sprinkler... you took me too literally.
Think of a photograph of the sprinkler when it's spraying in the location I said, then slide the photograph across your view.

Hi Webolife,
I knew I shouldn't have started this. I'm guessing here that the ion tail is at the front? So as I see it, the ion tail has to be travelling faster than the actual comet/coma. So what is pumping out ions faster than a speeding comet? Or is the whole ion tail, coma, dust tail thing sat inside some sort of envelope?

Hi GC, webolife,
I would not dismiss panspermia theory so easily. The jury is still in deliberation on that one.
There are, imhop, a lot of niceties concerning panspermia that favor it over a genesis on a 'self contained and isolated from the rest of the universe' Earth. Panspermia is a general term that has many variations, combinations, and possibilities. It does not necessarily explain the origin of life but may, in certain applications, explain the origin of life on Earth. The main argument against, seems to revolve around the difficulty of transport through the hostile environment of space.
Yes, it has been around for a long time, Anaxagoras (circa 500 BC) has been proposed as the originator of the theory in a recent [url2=http://shopping.msn.com/specs/anaxagoras-and-the-origin-of-panspermia-theory/itemid1001505990/?itemtext=itemname:anaxagoras-and-the-origin-of-panspermia-theory]book[/url2], and the theory has since reappeared many times.
This is one of those things that is not going to go away, as the issue is difficult to prove or disprove with the information available at this time. I would expect that some future discoveries from probes will shed some light one way or the other.

GC,
With regard to comet tails, the coma (head) of the comet is not necessarily moving ahead of the tail. The tail is typically pointing away from the Sun, regardless of whatever direction the comet is traveling. There are, in general, two types of tails-dust and ion. They can be pointing in differing directions, as far as comets are concerned, the word "tail" does not imply direction of travel. There really is no front or back.
I would post a link but they talk about "sublimating ices" and other such nonsense.
Try this instead:

Comets will sometimes exhibit two tails because of the ionization that occurs in the coma. Comets are, afterall, electrically charged bodies.

Ultraviolet light from the Sun can ionize the light gases in the coma, causing it to stream away from the nucleus in the direction of the "solar wind." The dusty component is less reactive to the "solar wind," so it tends to follow the orbital path of the comet.

As the comet moves around the Sun, the two tails will diverge from one another because the ion tail always points away from the Sun and the dust tail remains trailing along the orbital trajectory. The spike pointing toward the Sun is called the anti-tail, and results from the ion tail diverging by more then 90 degrees.

Hi Steve,
Thanks, it was the relationship between the ions and the Sun which I was missing. Fantastic images BTW.

Panspermia belongs in the Mad Ideas section, in my opinion. It is tantamount to saying that aliens seeded the Earth, because there is not one shred of proof for the concept. Frozen waterbears or bacterial spores found in near Earth orbit do not constitute anything except affirmation of the consequent.

"Modern" panspermia is a reaction to the realization, over a half century ago, that spontaneous generation of life on the earth under any conditions that could be hypothesized, has virtually no chance of success. Yet, as from the materialism thread, "here we are", so we/life must have come from somewhere else, and not only that, must have been repeatedly seeded, as from comets, over the supposed eons of time required by evolution... this very realization spawned first the mega buck flop SETI, then its offspring (native to my own alma mater the Univ of Wash) astrobiology, ie the search for conditions in the universe where life forms [extremophiles] might find possible habitation. The snipe hunt for earthlike planets is all about panspermia, despite the obvious fact that any such planets are likely to hold the same problem for spontaneous generation that our home planet exhibits. Holy shades of the church of cosmology, batman, I mean JL. :lol:
