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

  1. Visiting New Scientist web site the following time lapse movie caught my eye, see,

    http://www.newscientist.com/article/dn24667#.Upe1pNJwq0I from,


    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.

    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
