NASA Spacecraft Observes Electric-Blue Clouds Over Antarctica

 In early January, 2018, NASA's Aeronomy of Ice in the Mesosphere (AIM) spacecraft captured an image of glowing, electric blue clouds over Antarctica. These clouds are ice clouds, Earth's highest clouds. Located around 80 kilometres (50 miles) in the sky, the clouds are mainly composed of ice crystals with a fine mix of disintegrated meteorite. The electric-blue glow on the other hand is a by-product of sunlight shining through the high clouds.
