Comet Tails Blowing In The Solar Wind

NOAA forecasters may well be giving a low chance for solar flares at the moment, but flares or not the solar wind endlessly keeps blowing.  This image was taken by the STEREO-A spacecraft from outside Earths orbit.  It shows the solar wind blowing from right to left, with Comet Encke approaching the sun from the top left corner of the image downwards, and Comet Ison entering the frame from the mid left.  The influence of the solar wind on their tails is very easy to see in this very unique image.  The STEREO spacecraft was launched in 2006 and has been providing views of our star since then.  This video gives some great information about its mission:
