Too bad... it would be a hell of a show if it survives intact after its close encounter with the sun.

Booooo!
I was all geared up for an awesome show.
From brighter than a full moon to cosmic dust.
They should call it Comet Obamacare

When you dare to fly too near the Sun, it'll crack you up!

NEXT QUESTION:
What is the likelihood of Comet Ison ( estimate the comet to be around 3 miles in diameter) being broken up by the Sun's gravitational forces, into several pieces as it slingshots around the Sun ?
Astronomers estimated that the original
Comet ShoemakerLevy 9 (
formally designated D/1993 F2 ) may have had
a nucleus up to 5 km (3.1 mi) across .

Astronomers estimated that
the visible fragments of SL9 ranged in size from a few hundred metres to two kilometres across.
21 distinct impacts were observed, with the largest coming on July 18 at 07:33 UTC when fragment G struck Jupiter.
This impact created a giant dark spot over 12,000 km across, and was estimated to have released an energy equivalent to 6,000,000
megatons of TNT (600 times the world's nuclear arsenal).
[17]
Now since Comet Ison is estimated to be on slightly smaller than Comet ShoemakerLevy 9 was,
WHY WOULDN'T THE DAMAGE (if it breaks up) BE ANY DIFFERENT ? And if Comet Ison breaks up, can we expect its path to change, given the extra venting gases created by more surface areas to be heated up ?
And would the breaking up of Comet Ison speed up or slow down the shattered pieces velocity on its continued path out away from the Sun?
Or would it totally change the exit point in its slingshot around the Sun to widen the orbit out ?

How would a crushed Comet Ison compare to
the Tunguska event or the space rock that
carved Meteor Crater in Arizona ?
The
Tunguska event was an enormously powerful
explosion that occurred near the
Podkamennaya Tunguska River in what is now
Krasnoyarsk Krai,
Russia, at about 07:14
KRAT (00:14
UT) on June 30
[O.S. June 17], 1908.
[1][2][3]The explosion, having the
epicentre (60.886°N, 101.894°E), is believed to have been caused by the
air burst of a small
asteroid or
comet at an altitude of 510 kilometres (36 mi) above
Earth's surface.
Different studies have yielded widely varying estimates of
the object's size, on the order of 60 m (200 ft) to 190 m (620 ft).[4]It is the largest impact event on or near Earth in
recorded history.
(It is classified as an
impact even though the asteroid or comet is believed to have burst in the air rather than hitting the surface.)
[5]

The space rock that carved Meteor Crater in Arizona -- 570 feet deep and 4,100 feet (1.25 kilometers) across -- was blown into existence 50,000 years ago by an asteroid
roughly 130 feet (40 meters) wide.
So,
IF Comet Ison breaks up like
Comet ShoemakerLevy 9 did,
WHY shouldn't we worry about the possibilities of the damage the rubble from Comet Ison could do to our World,
if not on this pass, then on the next return trip into our orbit (who know how many years from now) ?
I found these videos that have very good information from the
Deep Impact Discovery Mission to Comet Tempel 1 and I thought they might be worth our time.

If the Tunguska object had reached earth a few hours earlier or later it might have taken out St. Petersburg, Russia, or Helsinki or Oslo or Whitehorse (Yukon Terr.). If St. Petersburg had disappeared the history of the 20th century would have been considerably different. Whitehorse, maybe not so much.

Published on Jun 18, 2013, is a little old, but thanks for the link.
One hour, 29 minutes and 2 seconds is a long video. But I'll watch it all later tonight.

I'd agree.

One hour, 29 minutes and 2 seconds of time well spent.
Thank you again for the link.
I recommend that video, but not if you're tired.
He connects the evidence very well, and lets the facts take us where they go, regardless of "established opinions and theories".

No, just no.

I’m guessing you’re not a scientist with journal access, and it would be a violation of the rules for me to give you the PDF, but even the abstract says all you need to know.
“A cavity region with essentially zero magnetic field has been discovered, with a width of 8,500 km along the trajectory around closest approach.”
In other words, no, comets are not “electric.” Please, let’s not make Free Repubic look like a forum for lunatics.
To: messierhunter
No, I'm not a scientist.
But it makes sense to me.
Why wouldn't comets be electrical?
Everything I know is subject to static electricity.
Why would comets be any different?

Not a matter of “would,” it’s a matter of “isn’t.” Comets have no “electrical” activity, no magnetic field, nothing. Their “glow” is caused by dust and ionized gas (which our spacecraft have also sampled).
To: messierhunter
I'm not sure I buy that THEORY for the total explainable reason for the glow and the tail of comets, any longer.

Well given Giotto’s data, it sure as heck isn’t “electricity.” In fact there’s no reason to think it’s anything other than what has already been verified. That is to say, dust and ionized gas.
To: messierhunter
So ~ you believe that exposure to X-Rays, Gamma Rays, and other bombardment of friction from the solar winds with its electrically charged particles would have no charging effect to the comets?

Now you’re putting words in my mouth. That is not what I said at all. In fact the surface of a comet is probably a bit statically charged like the moon ( http://www.nature.com/news/2007/070129/full/news070129-16.html ) but not as extreme thanks to the shielding effect of the comet’s coma. But that does not an “electrical comet theory comet” make, just as the moon is not a “comet.”
If you want to make Free Republic look like a home for pseudo-scientists and loonies, by all means, keep it up. I’m just trying to be a voice for reason.
