all! lets watch the realtime Ison journey meet the sun..provide by NASA!

I dunno it looks like there is something still driving that tail... how could the comet disintegrate due to heat yet the much weaker, finer dust trail survive?

I'm totally novice but... it seems there's still something with a tail following it.

I was thinking the exact same thing, but what the hell do I know.

This post on the other thread.. gives me hope.. isnt the white flare at the beginning indicating something solid ?

The tail does not follow a comet. It is very fine dust which is pushed away from the comet by the solar wind but continues to "fall" around the Sun.

The remnants of the comet are following the original orbit (as they must).
Headless Comets

isnt the white flare at the beginning indicating something solid ?

Even if the nucleus was intact, it is far too small to be seen in that image.

But if it did survive than ISON must be about 1/4 its original size.

Or could be just dust

it looks like the tail has flared but head is pretty bright.

It isn't the "heat" which caused the comet to break up, it was the gravitational forces resulting from passing so close to the Sun.

While small pieces and particles of the more volatile materials (ices) would vaporize, there is still actual "dust".

How small are we talking here Phage?

Since the original trajectory of Ison due to it's size/weight was suppose to slingshot it on a never to return path, we have a whole new scenario now.

Should we be concerned?

I couldn't say.

The mass of an object has no effect on the shape of its orbit. Fragments (and dust) will continue to follow the original path, gradually drifting apart.

Should we be concerned?

Only about not getting a nice show next month.

can u answer me "at what tempurature,, in a vacumn,, does "ice" ,,melt?

im thinking 5000 degrees, k should about do it.??
i could be wrong,, being in a vacumn,, could have significant,,un-imaginable,,unknows.???
,( hey turn off the A.C,, for a sec.its cold in here..)

"mass of an object has no effect on the shape of its orbit" lol tell that too a race car driver,, lol,,right,,lol

There is no temperature in a vacuum.

lol tell that too a race car driver,

A race car is not in freefall. An object in orbit is.

This does not look like dust to me.

Some of ISON indeed survived.

According to www.universe.com, out of 2000 sungrazers they have never seen one brighten like ison.
Now if ison came in spinning head on then on its way out it would have unexposed material . Ison survived and now its ass is burning like a vindaloo. Humble pie anyone?

reply to post by dreamfox1

Does this look like an intact comet or a cloud of disassociated material?

reply to post by symptomoftheuniverse

Comets don't burn. Nothing burns in space.

reply to post by Phage

Vaporise,sublimate whatever,and if theres oxygen in ison then it will burn.

There is no temperature in a vacuum. ?????????????????

Thanks for keeping it real buddy. It is hard to see what is personal truth and what is fact. I have checked up on some of the things you have posted in the past and I have found you deal in fact.



I am a curious novice. And I love facts. Between cheesy and his passion and you posting facts I have a budding interest in space.

That's right. How hot (or cold) is nothing?
