Electric Blue Clouds Spotted by NASA AIM Spacecraft Source: NASA Noctilucent Clouds Noctilucent Clouds At Extremely High Altitudes The image just released by NASA is spectacular. They show Noctilucent clouds, which are clouds that appear in the very high atmosphere during twilight in the hour after sunset.

Light Show From Space The season for Noctilucent clouds lasts from late May until August. NASA explains that as the earth's ...
