This is just one of the many things we learned from Varvara's mom, Natalia. Natalia works at the Atmospheric, Oceanic, and Space Science Department at the University of Michigan.
She did an amazing job of explaining solar winds and how the Aurora Borealis is produced, in terms everyone could understand.
In the afternoon, we watched a DVD: Cosmic Collisions. Many of the images in the film come from the U-M Space Science Department.
