Potentially Dazzling Comet ISON Should Survive Sun Encounter, Study Suggests
By Mike Wall, Senior Writer   |   October 09, 2013 02:01pm ET








The odds are pretty good that Comet ISON will survive its much-anticipated close solar approach next month, a new study suggests.

As long as ISON is a fairly typical comet — one with "normal" size, density and rotational characteristics — it probably won't disintegrate during its upcoming flyby, which will bring the icy wanderer within just 730,000 miles (1.2 million kilometers) of the sun's surface on Nov. 28, researchers report.

That's good news for skywatchers, for Comet ISON could potentially put on a dazzling show if it manages to weather its solar encounter. And it's also good news for scientists, who have been planning their most intense observations of the comet for after the flyby (since ISON will be easier to see from Earth after the approach than before). [Comet ISON: 8 Things to Know]





In the new study, Matthew Knight of the Lowell Observatory in Flagstaff, Ariz., and Kevin Walsh of the Southwest Research Institute in San Antonio conducted simulations of Comet ISON's upcoming solar approach, then put the results in context by looking at how other "sungrazing" comets have performed during their encounters with our star.

The possible outcomes for Comet ISON are total disintegration; initial survival with a breakup coming later, perhaps days or weeks after the Nov. 28 flyby; and full survival for another orbit around the sun. Which one of these will actually occur depends on ISON's size and density, as well as the nature of its rotation (how fast it's spinning, and in which direction), researchers said.

Comets less than about 0.12 miles wide (0.2 kilometers) face destruction by the sun's heat, which can evaporate off all of their ices. But scientists think ISON is big enough to deal with this issue; most estimates place the comet's core between 0.12 miles and 1.2 miles across (0.2 to 2 km).

Another threat comes from the immense gravitational pull of the sun, which can tear apart comets that are unusually light and fluffy. But as long as ISON is of roughly average density, it should be able to hold together, researchers said.

None of this is set in stone, of course, since most of the key characteristics — including Comet ISON's exact size, density and spin — remain unknown. And it's notoriously difficult to predict the behavior of comets, especially "dynamically new" ones like ISON making their first trip to the inner solar system from the distant, frigid Oort Cloud.

"Whether or not disruption occurs, the largest remnant must be big enough to survive subsequent mass loss due to evaporation for Comet ISON to remain a viable comet well after perihelion," Knight said in a statement.

Meanwhile, another new study suggests that Comet ISON might exhibit a burst of activity a week before its close solar encounter.

Researchers used NASA's Hubble Space Telescope to measure the rotational pole of ISON's core and determined that only one side of the comet is being heated thus far as it streaks toward the sun.

But that should change on or around Nov. 21, when Comet ISON ducks inside the orbit of Mercury, the solar system's innermost planet, team members said.

"Since the surface on the dark side of the comet should still retain a large fraction of very volatile materials, the sudden exposure to the strong sunlight when it gets closer to the sun than Mercury could trigger huge outbursts of material," study leader Jian-Yang Li, of the Planetary Science Institute in Tucson, Ariz., said in a statement.

Both studies were presented today (Oct. 9) at the American Astronomical Society's Division for Planetary Sciences 45th annual meeting in Denver.

Here is another ISON informational video that I don't think has been posted here yet. There are 1 or 2 videos by this same fellow posted in this thread. Here he is taking a detailed look at Hubble pics of ISON taken a few months ago. Details of ISON still seem to be a LITTLE strange!!

And another video that is somewhat different. ?? ISON + +

No way to know if this is factual?

As we reported yesterday,http://www.universetoday.com/105380/new-data-will-comet-ison-survive-its-close-perihelion-passage/

the latest data on Comet ISON indicates there is some encouraging news as far as the Comet surviving perihelion, its closest approach to the Sun. While some are all doom and gloom about the potential for Comet ISON putting on a good show, these latest images indicate that as of now, this comet is alive and doing well!

"We really do not know what comet ISON is going to do when it gets near the Sun," wrote astronomer Karl Battams of the Comet ISON Observing Campaign website. http://www.isoncampaign.org/karl/ison-is-just-fine

"But what we can say for certain, right now, is that comet ISON is doing just fine! It continues to behave like a fairly typical, if somewhat smaller-than-average, Oort Cloud comet. It has given no indication that it has fragmented and while such an event can never be ruled out, we see no evidence or hint that the comet is in any imminent danger of doing so. Any reports to the contrary are just speculation."

You can read more from Battams   http://www.isoncampaign.org/karl/ison-is-just-fine

about the current status of ISON, but just take a look at some of these gorgeous latest images from a variety of astrophotographers:

Comet ISON is doing just fine!
Submitted by Karl on Wed, 10/09/2013 - 08:23
There has been a lot of speculation brewing over the past few days that C/2012 S1 aka comet ISON may either have already fragmented and fizzled, or is about to do so at any moment. I'm not going to point directly to any sources that are making these claims as I don't think those articles deserve the web traffic. Instead, I'll let you judge for yourselves: does this look like a fizzled out comet?

Who are the CIOC Team?
  The CIOC Team comprises the following scientists:

Carey (Casey) Lisse (Johns Hopkins University Applied Physics Laboratory, Laurel, MD)
has been active in the fields of astronomy and physics since 1985, where he began as an instrument scientist at NASA/Goddard on the Nobel prize winning COBE project. He later moved over to planetary studies, writing his dissertation on comets detected in the COBE all sky survey. Since then he has focused primarily on comets, making important discoveries in X-ray emission from comets, and working on the NASA Deep Impact mission from start to finish including using the Spitzer Space Telescope to observe dust excavated from Comet 9P/Tempel 1 by the DI Impactor. He also studies asteroids and x-ray emission from planets and comets, and searches for the presence of asteroids and comets around other starts. Casey is the Chair of the CIOC Team, overseeing the activities of the CIOC.


Karl Battams (U.S. Naval Research Laboratory, Washington, DC) is an astrophysicist and computational scientist based in the solar physics group at NRL.
He has been in charge of the Sungrazer Project since 2003, overseeing most of the project's 2500+ sungrazing comet discoveries. In addition to his work with sungrazing comets, he performs software development, data processing and visualization for the NRL Solar Branch. He has a passion for astronomy outreach through presentations and video projects, including having filmed with National Geographic and the BBC, the latter for the acclaimed "Wonders of the Solar System" series. Karl's primary role on the CIOC is to interface with the solar observatory operations teams (SOHO, STEREO, etc) that will provide critical observations of Comet ISON in the days immediately surrounding perihelion. He tweets as @SungrazerComets.


Michael DiSanti(NASA Goddard) has more than 20 years experience in the study of native ices in comets through ground-based high resolution spectroscopy of volatiles in the 1 - 5 micron spectral region. This has led to abundance measurements of up to 10 parent molecules, and reveals compositional diversity among more than two dozen comets observed to date.


Yan Fernandez (University of Central Florida, Orlando, FL) is an astronomer who has been studying comets and asteroids since the mid-1990s.
He has studied comets, asteroids, Trojans, Centaurs, and small moons at IR, visible, and radio wavelengths for over ten years with the goal of determining their physical and compositional properties. He is the PI of the Spitzer SEPPCoN program to characterize the size, albedo, and color of 100 JFC comets. A member of the NASA CIOC team, he will lead the IRAC photometry data reduction efforts, and will help interpret Comet ISON in the context of other comets.


Michael Kelley (University of Maryland, College Park, MD) is an astronomer who observes and models comet dust to find out what it is made of, and where it comes from.
He is also similarly interested in asteroid surfaces, and their thermal properties. His first research paper on comets was about Comet Halley in 1985, when he was at the young age of 7 years, although it's distribution was limited to his father's notebook. Mike's role on the CIOC is primarily based on his expertise with comet dust and mid-infrared spectroscopy, and his association with the Deep Impact science team.


Matthew Knight (Lowell Observatory, Flagstaff, AZ) is an astronomer specializing in comet nucleus and coma studies.
He studied sungrazing comets for his Ph.D. thesis and has spent 150+ nights observing comets in optical and near-IR wavelengths. Matthew's primary role on the CIOC is to monitor ISON and help predict its behavior near perihelion and beyond in order to help ground- and space-based observers optimize their observations.


Ron Vervack (JHU Applied Physics Laboratory) is a planetary scientist who has been involved in NASA projects since 1985 when he started working on Voyager.
Nowadays, he splits his time between spacecraft observations of planetary atmospheres and ground-based infrared observations of comets and asteroids. Ron's role on the CIOC reflects his diverse interests, providing connections to both the ground- and space-based scientific communities. He is the lead on a moderate-resolution infrared observational campaign at NASA's IRTF to study the gas and dust comas of comet ISON and a member of two teams that will use both the IRTF and Keck Observatory to study the gas coma of ISON using high-resolution spectroscopy. As a member of the MESSENGER Science Team, he will lead the MESSENGER observations of ISON during its closest approach to the planet Mercury.



Elizabeth Warner (University of Maryland, College Park, MD) is an amateur astronomer who also does informal astronomy education and public outreach.
During the Deep Impact Mission, she served as the "Liaison to Amateur Astronomers," she was/continues as the webmaster for the EPOXI (and DI3) mission, and coordinates the Amateur Observers' Program started during Deep Impact and continued for other NASA Small Body Missions. She also coordinates programs at the UMD Observatory.



Padma Yanamandra-Fisher (Space Science Institute, Boulder, CO), physicist and astronomer, seeks to study light scattering in various astrophysical environments (planetary atmospheres and ring systems, comets, etc.) using polarimetry and thermal spectrophotometry.
Her research on atmospheres of Jupiter and Saturn collided with cometary dust modeling via participation in the D/Shoemaker-Levy 9-Jupiter campaign of 1994, and other celestial impacts on Jupiter in 2009-2011. She loves to share her passion via outreach and social media. Her role in CIOC is a confluence of science through telescopic observations and outreach via Facebook collaboration with a global network of amateur astronomers/comet imagers.

Comet ISON: New NASA Trajectory - JPL Orbital Diagram, Published Oct. 15, 2103

                                       

Amaterasu

Does a "new trajectory" mean the comet made course corrections and now has a new path?
"If the universe is made of mostly Dark Energy...can We use it to run Our cars?"

Supposition of course ~~~~ either ISON changed course or, "SOMEONE" made some sort of mis-calculation in the projection of its course through the solar system.

With what little I have seen in some of the video presentations on ISON, it appears that even at the highest technical levels, we really are pretty ignorant when it comes to actually "knowing" what any heavenly body can or will do, as it transverses the heavens. The word "prediction" seems to be a better word to use in this regard. Astronomers "predicting" what ISON can or will do is not that different in possibilities from, the weather men trying to predict what "mother nature" is going to do, at any given time in the future.  :))

::)
Bashar's mate says it is Jesus disguised as a space ship, disguised as a comet.   :o

sky otter



ok P
calling you on this one

where does it say anywhere anything about bashar's mate at that link?
cause i couldn't find it
maybe you forgot to add a different link with that specific piece of info

and really..you're now going with before it's news as a reliable source ?   ???


if you go to the link that i put in the last post
here's i'll give it to you again

http://hubblesite.org/hubble_discoveries/comet_ison

and you page down a bit you will see how some folk have come up with this space ship idea
it is in the unretouched photos where they are get the image as it looks to be in three pieces

that's why i posted that link..even knowing so very few would ever look..
many photos so that you could make a judgement for yourself and not
fall for any of the sillyness

but hey.. i ask myself - why bother anymore

That was a joke Sky. It was about conspiracy theories generally not you.  I was laughing to myself the other day waiting for someone to say that ISON was going to be involved in a Doomsday scenario and when nobody did I did it instead for comic effect.

Bad joke obviously.  :-[

We all ask ourselves that.  I bother because I enjoy it but I don't know how constructive it all is.  Enjoying something is good enough reason.  There are some good people here too.  I'm not exactly Doctor Evil myself to be fair.

Much love x

Unknowncountry Weekender: The Coming of Comet Ison in Astronomy and Astrology
Friday, September 27, 2013
We are getting a sense of astronomical déjà vu here at Unknown Country: Comet ISON is looming in our skies and already there are rumors of an accompanying spaceship, or even that the heavenly body itself is not a comet at all but a triangular-shaped UFO. Such stories are not presently supported by any published scientific findings.

.......Contrary to the internet rumors already starting about ISON, there is presently no convincing evidence that any sort of large object is accompanying it. Even if such an object is observed, it's likely to be the same as the others that are seen near comets--simply a natural phenomenon. However, if such things as starships exist, they would need water, and following an outgassing comet as it approaches a star would be one way to collect it.


i think you just have a case of the new dad jitters...have a few large cups of coffee and  as yoiu really bounce off the walls you'll see the difference  ;)

hugs ;D




Deuem.. really cool... as ususal....thanks
