Waspie_Dwarf Posted November 28, 2013 #1 Share Posted November 28, 2013 Observers have not yet recovered ISON after it rounded the Sun. The latest SOHO images do not show it. It is looking increasingly likely that it has not survived and that the "Comet of the Century" is no more. 1 Link to comment Share on other sites More sharing options...
JesseCuster Posted November 28, 2013 #2 Share Posted November 28, 2013 Phil Plait tweeted that something was observed coming round the other side of the sun but it's not clear exactly what and in what condition. So much for the hyberbole about it potentially being brighter than a full moon. Link to comment Share on other sites More sharing options...

Waspie_Dwarf Posted November 28, 2013 Author #4 Share Posted November 28, 2013 Phil Plait tweeted that something was observed coming round the other side of the sun but it's not clear exactly what and in what condition. So much for the hyberbole about it potentially being brighter than a full moon. The experts have always said it had the potential to be brighter than the full moon IF it survived it's encounter with the Sun. No hyperbole, just the non-specialist press ignoring some of the facts. I hope not...that would be more than a little disappointing... It's par for the course with comets. They are unpredictable by nature. Link to comment Share on other sites More sharing options...
+susieice Posted November 28, 2013 #5 Share Posted November 28, 2013 From what I watched on NASA they're pretty sure it broke up. I'm hoping something survived. Link to comment Share on other sites More sharing options...
bison Posted November 28, 2013 #6 Share Posted November 28, 2013 (edited) The article linked below includes a picture of the trail ISON left behind as it approached the Sun, and its faint remains emerging out the other side. No nucleus, apparently, merely debris. http://www.nbcnews.c...-sun-2D11670914 Edited November 28, 2013 by bison Link to comment Share on other sites More sharing options...
+susieice Posted November 28, 2013 #7 Share Posted November 28, 2013 Here's what Phil Plait posted a few minutes ago. He was on the live you tube discussion with NASA, so that's linked again here.

Waspie_Dwarf Posted November 28, 2013 Author #8 Share Posted November 28, 2013 Comet Ison destroyed in Sun passage Comet Ison was severely battered in its encounter with the Sun, and largely destroyed.Telescopes saw the giant ball of ice and dust disappear behind the star, but only a dull streamer emerge. Astronomers continued to search for the object, but it eventually became clear that the much vaunted "Comet of the Century" had gone out with a whimper. Read more...

Waspie_Dwarf Posted November 28, 2013 Author #10 Share Posted November 28, 2013 Comet ISON FizzlesThese images from NASA's Solar Terrestrial Relations Observatory and the ESA/NASA Solar and Heliospheric Observatory show Comet ISON growing dim as it made the journey around the sun. The comet was not visible at all in NASA's Solar Dynamics Observatory. The comet is believed to have broken up and evaporated.While this means that Comet ISON will not be visible in the night sky in December, the wealth of observations gathered of the comet over the last year will provide great research opportunities for some time. One important question will simply be to figure out why it is no longer visible.Credit: NASA/SDO/ESA/SOHO/GSFCSource: NASA Goddard - Multimedia 1 Link to comment Share on other sites More sharing options...
+susieice Posted November 29, 2013 #11 Share Posted November 29, 2013 (edited) I was so looking forward to going out an hour before sunrise on December 1 (my birthday) and seeing an amazing sight, but alas, gone it is. If I understood what I've been reading right, most comets come from within the solar system but this one came from the oort cloud and took 50 million years to get where it was today. The data gathered will do much to help scientists understand the composition of comets and will tell a story about the region in space where this comet came from. I will miss my birthday memory but I can wait for the next one. Edited November 29, 2013 by susieice 2 Link to comment Share on other sites More sharing options...
Imaginarynumber1 Posted November 29, 2013 #12 Share Posted November 29, 2013 (edited) I had a feeling that ISON would break up upon it's encounter with the sun. When it didn't brighten up a few months ago when expected I was afraid that it would be a let down, sky watching-wise, that is. There are always more comets and who knows when the next will come!! R.I.P. ISON. We hardly knew you. Edited November 29, 2013 by Imaginarynumber1 3 Link to comment Share on other sites More sharing options...
regeneratia Posted November 29, 2013 #13 Share Posted November 29, 2013 I personally see Ison continuing on. I reserve the right to change that opinion as more information is forthcoming.

Imaginarynumber1 Posted November 29, 2013 #14 Share Posted November 29, 2013 Could fragments of ISON survived? Of course. No one said otherwise. It certainly did not survive it's encounter with the sun, however, enough to go on to become the "comet of the century" that it was hailed as. I hope the nucleus did survive, but it's not likely. 1 Link to comment Share on other sites More sharing options...

R.I.P. ISON. We hardly knew you. Your post here kind of got me thinking. I watched the live feed on the NASA channel and haven't watched the you tube link to it again, but I remember one of the panel saying that it's believed a passing star could have caused a disturbance in the oort cloud and sent ISON on it's path through our solar system. I guess my first question is how do they know the origin of ISON and my second, what is the probability that ISON wasn't the only one put on this trajectory? ISON wasn't seen until 2010, so is it possible that there are others that were disturbed at the same time? I know they don't necessarily have to be following the same path as ISON. I'm no astronomer and I don't often come into this part of the forums other than to browse but what I was hearing about this comet and what it could have become peaked my interest. 2 Link to comment Share on other sites More sharing options...

I'm not too well versed in the subject, but I believe that they know where ISON came from based upon its speed, trajectory and composition. The oort cloud is massive, so any large passing body could have disturbed it. Even a nearby collision, i suppose. There could be any number of other comets heading this way as we speak. Just keep your eyes on the sky! 2 Link to comment Share on other sites More sharing options...

Maybe some of it did survive though it probably won't be as bright as originally thought. 1 Link to comment Share on other sites More sharing options...
+susieice Posted November 29, 2013 #22 Share Posted November 29, 2013 I rechecked Plait's site and 2 new updates have been added. Apparently what first emerged on the other side at first appeared to be debris but now it seems to be massing.

regeneratia Posted November 29, 2013 #25 Share Posted November 29, 2013 (edited) ISON Is not dead. http://www.solarham.net/index.htm Updated 11/29/2013 @ 02:00 UTC Comet ISON Recap Thursday was a day full of excitement and also many questions in regards to Comet ISON. The eyes of sky watchers around the world were tuned into a number of space weather websites wondering if the sungazing comet would survive its close encounter with our star. Comet ISON brightened throughout the day as it neared the sun, with a long dusty tail visible behind it in both LASCO and STEREO imagery. When it came time for the predicted perihelion (closest approach to the Sun) at 18:44 UTC, initial indications were that ISON did not survive the intense solar atmosphere and burned up. Comet ISON was declared dead by many. After a few hours had passed, what appeared to be a fragment of the comet re-emerged in both LASCO C2 and STEREO Ahead coronagraph imagery. Did ISON survive? Imagery and video below appear to support that scenario. More updates to follow regarding this event. Stay Tuned! http://www.solarham.net/index.htm http://www.spaceweat...snippet-6324727 CANCEL THE EULOGY: Comet ISON flew through the sun's atmosphere on Nov. 28th and the encounter did not go well for the icy comet.
