Astro-Image of the Day: Aurora Borealis

This image shows a broad swath of aurora over the northern United States.

Scientists have discovered that some of the aurorae are polarized. This discovery will help scientists better understand Earth's upper atmosphere and magnetic field, and will help them study the Sun wind.

Best,
Chris
