Video: Watch a Solar Storm Slam into Earth

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.

To learn more about new data processing techniques for STEREO data and how they are helping scientists to better understand solar storms, see our previous article.

    Should be “Coronal”, not “Cornal”

    It looks like the CME got smaller when it reaches Earth compared to what got ejected from the Sun. Unless the Earth representation is not the real scale of Earth.
