Best viewed at 720p and fullscreen, this is truly spectacular. More from Universe Today:

Newly reprocessed images from NASA’s STEREO-A spacecraft, allow scientists to trace the anatomy of a Coronal Mass Ejection in December 2008 as it moves and changes on its journey from the Sun to the Earth. Using a new technique, heliophysicists can now identify the origin and structure of the material that impacted Earth, and connect the image data directly with measurements at Earth at the time of impact.

The different views from left to right are at different scales. The yellow dot is Venus and the blue dot is Earth. Closer to Earth is a dial showing the solar wind density changes at Lagrangian point L1 where the ACE and Wind spacecraft recorded the event.

I, for one, welcome our new ionized particulate overlords.
