NASA released a spectacular image of a huge “dragon” aurora charging quietly across the night sky over Iceland.
The natural phenomenon is caused by particles emanating from the sun that collide with Earth’s atmosphere to put on a gorgeous light show.
“Have you ever seen a dragon in the sky? Although real flying dragons don’t exist, a huge dragon-shaped aurora developed in the sky over Iceland earlier this month,” the space agency said in a post.
NASA added: “The aurora was caused by a hole in the sun’s corona that expelled charged particles into a solar wind that followed a changing interplanetary magnetic field to Earth’s magnetosphere.”
This dragon aurora is mysterious because it appeared during a time of low sunspot activity, according to NASA, which means the sun is not emitting as many charged particles as it normally does.
