Panorama by @babaktafreshi
The World at Night project
Swipe left to see this 2-panel image. The aurora display was so extended across the sky that even my 14mm lens was not wide enough to capture the entire view. Panorama was the only way to show the real beauty of this scene above waterfalls streaming out of a lava field into Hvita river in Iceland. The dusk was still visible when the northern lights emerged. The lights are all about high energy particles from the sun (solar wind) crashing into Earth atmosphere. On the ground we are shielded from this intense radiation and peacefully enjoy the show. The red light is created by glowing oxygen more than 120 miles (200 km) above our planet’s surface, while the green originates much lower―only about 60 miles (100 km) up. The purple originates with nitrogen.
