Behold: The beauty of our home planet! ? The orange hue surrounding Earth, known as airglow, diffuse bands of light that stretch 50 to 400 miles into our atmosphere.

Airglow reveals some workings of the upper reaches of our atmosphere. It can help scientists learn about the movement of particles near the interface of Earth and space, including the connections between space weather and Earth weather. Satellites offer one way to study this dynamic zone. Our Ionospheric Connection Explorer satellite that launches early in the morning of Nov. 7 will help scientists understand the physical processes at work where Earth’s atmosphere interacts with near-Earth space.
