The Moon & Earth Noctilucent Clouds | International Space Station

The Moon & Earth Noctilucent Clouds | International Space Station

Astronaut Matthew Dominick: "A sliver of Moon rises out of noctilucent clouds and appears to look towards the horizon awaiting the imminent sunrise."
Noctilucent clouds, or night shining clouds, are the highest clouds in Earth's atmosphere, composed of tiny water ice crystals, and are only visible when the sun is below the planet's horizon illuminating them.

The Sun’s activity will once again ramp up until solar maximum, predicted for 2025. This high solar activity is warming Earth's upper atmosphere and breaking apart water molecules required to form noctilucent ices. However, for reasons researchers do not fully understand, Solar Max does not always extinguish the clouds.
