Investigating rare blue clouds over the Arctic
Today’s Video of the Day from NASA describes a mission to gain a better understanding of polar mesospheric clouds (PMCs).
The rare, electric blue clouds form in the mesosphere 50 miles above Earth’s poles during the summer season just after sunset.
In July 2018, NASA sent a balloon to observe the clouds high above the Arctic.
The balloon captured millions of high-resolution photos which may help experts better understand turbulence as well as other weather processes.
