northern lights appear as ribbons of green and purple light streaking across the sky and reflected in the water below. There are some mountains to the left side of the image.The northern lights, or the aurora borealis, are beautiful dancing ribbons of light that have captivated people for millennia. But for all its beauty, this spectacular light show is a rather violent event. at speeds of up to 45 million mph , but our planet's magnetic field protects us from the onslaught.
Within the auroral zone, it's best to be as far away from city lights as possible to maximize visibility. But it's pretty tricky to get into the middle of the Arctic wilderness, even with a guide, so it's best to base yourself in a destination with solid infrastructure, like Fairbanks, Alaska; Yellowknife, Canada; Tromsø, Norway; Abisko National Park, in Sweden; Rovaniemi, Finland; and pretty much anywhere in Iceland.
"While some auroral emissions occur in both hemispheres at the same magnetic local time, other emissions appear in opposing sectors in the two hemispheres at different times — for example, pre-midnight in the Northern Hemisphere and post-midnight in the Southern Hemisphere," Petrinec told Space.com.is due in part to the sun's magnetic field interfering with Earth's magnetic field, but research into the phenomenon is ongoing..
Astronomers have even caught glimpses of apparent auroral activity in other solar systems.
