Earth's Auroras Make Rare Joint Appearance in a Feature Film
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 -- conjugates - of each other. Full Story

Polar Quantifies Magnetospheric Drivers of Upper Atmospheric Chemistry Changes
The importance of magnetospheric dynamics on the aeronomy of the upper atmosphere is known but it has never been clear how important, how extensive, how often, and how extreme the effect can be. Full Story
