Earth’s auroras recorded simultaneously

Scientists using NASA’s Polar spacecraft have captured the first-ever movie of auroras dancing simultaneously around both of Earth’s polar regions. During a space weather storm on October 22, Polar’s Visible Imaging System observed the aurora borealis and aurora australis (northern and southern lights) expanding and brightening in parallel at opposite ends of the world. The images confirm the three-century old theory that auroras in the northern and southern hemispheres are nearly mirror images of each other.
