Will Comet ISON survive tomorrow’s close encounter with the Sun? Approaching to within a solar diameter of the Sun’s surface, the fate of one of the most unusual comets of modern times will finally be determined. The comet could shed a great amount of ice and dust into a developing tail — or break apart completely. Unfortunately, the closer Comet ISON gets to the Sun, the harder it has been for conventional telescopes to see the brightening comet in the glare of the morning Sun. Pictured in the above short time lapse video,Comet ISON was captured rising over the Canary Islands just above the morning Sun a few days ago. If the comet’s nucleus survives, the coma and the tails it sheds might well be visible rising ahead of the Sun in the next few days or weeks. Alternatively, satellites watching the Sun might document one of the larger comet disintegrations yet recorded. Stay tuned!

COMET ISON, R.I.P.: Evidence is mounting that comet ISON did not survive its brush with the sun earlier today. At 01:45 EST on Nov. 28th, Thanksgiving Day in the USA, the comet was supposed to pass a little more than a million miles above the surface of the sun. As a new movie from SOHO shows, the comet had already disintegrated. Click to set the scene in motion, and pay careful attention to the head of the comet:
Again from Spaceweather:
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. Just before perihelion (closest approach to the sun) the comet rapidly faded and appeared to disintegrate. This prompted reports of ISON’s demise. However, a fraction of the comet has survived. Click on the image below to see what emerged from Comet ISON’s brush with solar fire:
In the movie, Comet ISON seems to be falling apart as it approaches the sun. Indeed, researchers working with NASA’s Solar Dynamics Observatory said they saw nothing along the track that ISON was expected to follow through the sun’s atmosphere. Nevertheless, something has emerged. Whether this is a small scorched fragment of Comet ISON’s nucleus or perhaps a “headless comet”–a stream of debris marking the remains of the comet’s disintegrated core–remains to be seen.
There is more over there.

ISON is truly
“The Little Comet That Could”!
