Comet Tails ?????

Google is not information. Google is just a pointer to information.

If you are too stupid to be able to verify that man went to the moon, then you are probably too stupid to use Google effectively anyhow, so it is just as well that you don't even try.

I'll take a wild guess that you don't believe that any of the missions in any of the links I provided actually took place... which begs the question.... why are you even participating in an astronomy forum into the first place? It only serves to show the entire world that you don't have the brains that were given to a ripe cumquat.

Don't be silly.
Even a "ripe cumquat ", would never implicitely trust one source of
information, and not want to examine the facts for themselves.

Places like NASA just want you to accept their science as "Correct" and not
ask too many questions.

I heard that we tried to land on the comet but were not able to do it. If comets are snowballs they are still going to melt into non-existence when they round the Sun. So comet tails cannot be vapor and dirt.

You "heard"? Did you read the links? We absolutely landed on a comet! Comets are not literally snowballs. You never "heard" of Google?

I go more by common sense and the facts as given by televised documentaries than by Google. And even the documentaries tend to go off the deep end sometimes. The point is, if comets are not snowballs with vapor trails, we still need to find out just what they are.

It's actually quite narrow minded to think that in a solar system as diverse
as it is, that comets or asteroids would ALL be identical in their
compositions.
Why NASA keeps trying to sell us one story always makes me wonder why.

The natural processes that create comets and asteroids are surely consistent to some degree.

Most have one tail.Some have two,and some no tail at all.Some tails are a million miles long(WOW) What are these tails made off? I think dust??? Some say water.Is the sun not only reflecting light of these dusty tails,but also creating them? Photons from sun do effect the direction of tails when comet swings around the sun. Is it possible comets leaving the Oort cloud have no tails,and tails come to be when comet enters the solar system? I saw Halley comet when I was 5 or 6 Many moons ago.Treb&bert


That some of the gas has electrically charged particles explains the second tail.

Double-A

No Bert, you almost certainly did not see Halley's comet when you were 5 or 6 years old. The last appearance was in 1986, and I rather doubt that you are only about 37 years of age now. The appearance before that was in 1910, and I doubt very much that you are 113 or so years old now.

It must have been a different comet that you saw when you were 5 or 6 years old. A good project for you would be to research what comet was both in the sky and was also a bright naked-eye object when you were about that age....

I would agree with this opinion. We will always have lots to learn about all things in our solar system.

If you really think that NASA is stuck on just one story, well, you have not read enough about the subject matter at hand. Science in general and astronomers in particular are constantly looking to update their views about "the way things really are", and that is not likely to change anytime soon. That's the way science works...

Oh look, I used Google to find a Wiki article... which automatically means you will probably find a lot of fault with the results...

*** you are one clueless dummy, treBert. By the time comets are
visible to the naked eye, they have two tails.
One trails in the direction of travel and the other is blown in the
direction of the Solar Wind, pointing away from the Sun.

Not exactly correct. 2 tails, yes, but neither one trails in the direction
of travel, unless I am not understanding what you mean by this. Both tails
point away from the Sun, but the dust trail curves and the gas (ion) tail
does not...

*** my apology ... this was treBert asking the question and I tried
to make the answer as simple as possible. It appears, he's never
heard of Google ...

Should we just go to Google and never talk things over? Shame on us.Treb&Bert

Well,....at least I won't disappoint you when I say that two wrongs, are not
likely to make a right..

I have nothing against seeking out knowledge.
But I do have a problem when NASA is doing it, and always seems to be trying
to prove their findings before they even start any experiment.
THAT,.....Is bad science......Cart before the horse, kind of thing.

......It's the kind of science that gave us Global warming/coooling climate
change,.....or the E.U. government.
