Studying gravity waves in electric blue clouds
Today’s Video of the Day from NASA Goddard features striking images of electric blue polar mesospheric clouds (PMCs).
These clouds, which only form above Earth’s polar regions, are composed of ice crystals that appear bright blue or white when they are struck by sunlight.
NASA launched a balloon mission that was developed to help scientists gain a better understanding of the complex process of turbulence.
The gravity waves that cause turbulence are usually invisible, but can be seen as they move through PMCs.
