This is seriously science-geeky, but cool. November 25: Comets ISON and Encke -- gone from Earth view; spacecraft take over. The comet has moved too close to the Sun for practically any visible-light observations. But now its entering the fields of view of solar observatories in space, which are watching the Sun from various directions far from our home planet. Several days ago ISON entered the very wide view of NASAs STEREO-A, one of two twin craft nearly on the far side of the Sun from us. Heres a spectacular movie, four days long (November 19–23), of Comets Encke and ISON making their way with tails flapping in gusts and waves of the solar wind. A labeled frame is below. The images are processed to display differences from each frame to the next. More about the movie and comet tails in the wind, from Karl Battams of NASAs Comet ISON Observing Campaign (CIOC) at isoncampaign.org/ison-encke-nov19-23
