Rare Electric Blue Clouds Observed by NASA Balloon

The video explains polar mesospheric clouds (PMC's), which are visible during twilight and form above Earth's polar regions. These clouds are sensitive to environmental factors and are affected by gravity waves, which cause turbulence in the atmosphere. To study these phenomena, scientists launched a balloon to observe gravity waves in PMC's, capturing data that can improve weather forecasts and our understanding of atmospheric processes affecting satellites.
