A NASA spacecraft has captured its best video yet of the icy Comet ISON streaking toward a Thanksgiving Day encounter with a sun, a close shave that the comet might just not survive.

The latest video of Comet ISON comes from NASA's STEREO-A spacecraft, one of several sun-watching space observatories tracking the comet's close encounter with the sun on Thursday (Nov. 28).

"This movie from the spacecraft's Heliospheric Imager shows Comet ISON, Mercury, Comet Encke and Earth over a five-day period from Nov. 20 to Nov. 25, 2013," NASA officials wrote in a video description. "The sun sits right of the field of view of this camera." [Comet ISON's Thanksgiving Sun Encounter: Complete Coverage]

Known officially as C/2012 S1 (ISON), Comet ISON is what scientists call a "sungrazer" comet because its orbit brings it extremely close to the sun. It is that extremely close solar shave, less than one diameter of the sun away, that has scientists guessing as to whether ISON will survive the encounter.

In the video, Comet ISON appears as a bright object streaking from left to right as it draws ever closer to the sun. Comet Encke, meanwhile, appears as a dimmer object moving from the upper left to lower right. The planets Mercury and Earth and labeled in the STEREO-A view.

Looks like Ison is now an ex-comet as it appears it looks like it just fizzled like a spider on a hot stove, which is a pity and does make the TV programs that were on about it look a bit ridiculous.

Marvellous and colourful. I would like to ride on the tail of a comet one day.

The good news is that it has appeared from behind the sun - but it took one hell of a beating but we should be seeing it in the sky next week. By the way there is a comet near the Big Dipper which looks pretty good through binoculars or a small telescope I am going to keep an eye out for that one.

I can't watch the videos as I'm in Canada. Have been waiting to be able to see the comet and am so sad that it is just a tiny remnant of it's former glory. We have had cloud cover for weeks it seems. Still hoping it will become visible to the naked eye as it continues it's journey though.
