A trail of SpaceX Starlink satellites are visible in front of a haunting green aurora, as witnessed by AuroraWatchers.com in a video shot near Fairbanks on Sept. 2.
The aurora borealis, also known as the northern lights, is the rippling night-sky light display found at the northernmost reaches of the Earth. The south has a corresponding aurora australis, also known as the southern lights. The northern and southern auroras occur when charged particles released by the sun, called the solar wind, are guided along the Earth's magnetic field to its poles and interact with particles in the upper atmosphere there. How to see the Northern Lights.
