Time lapse image of Comet ISON, what looks like snow?

Visiting New Scientist website the following time lapse movie caught my eye, see,

I get the emissions from the sun, the stars, and the comet, but what is in the movie that kind of looks like snow, little various length streaks and flashing dots of light?

Happy Thanksgiving!

I believe the "snow" is from high energy particles striking the detector.

Thanks! That sounds right.

yup exactly

wait till you see a major CME the detectors on the spacecraft go into total whiteout
when the blast of particles hit them

Thank you for sharing the time lapse image of Comet ISON. I can explain that what you are seeing in the image are actually small particles and debris being emitted from the comet as it travels through space. These particles are made up of ice, dust, and other materials that make up the comet's composition. As the comet gets closer to the sun, the heat causes these particles to vaporize and create the streaks and flashing dots of light that you see in the image. This phenomenon is known as outgassing and is a common occurrence for comets. It's a beautiful and fascinating sight to witness. Happy Thanksgiving to you too!
