APOD: The Veins of Heaven (2019 Jul 26)

Image The Veins of Heaven

Explanation: Transfusing sunlight through a still dark sky, this exceptional display of noctilucent clouds was captured earlier this month, reflected in the calm waters of Vallentuna Lake near Stockholm, Sweden. From the edge of space, about 80 kilometers above Earth's surface, the icy clouds themselves still reflect sunlight even though the Sun is below the horizon as seen from the ground. Usually spotted at high latitudes in summer months the night shining clouds have made a strong showing so far during the short northern summer nights. Also known as polar mesopheric clouds they are understood to form as water vapor driven into the cold upper atmosphere condenses on the fine dust particles supplied by disintegrating meteors or volcanic ash. NASA's AIM mission provides daily projections of noctilucent clouds as seen from space.

What a stunningly beautiful image. I haven't seen any noctilucent clouds this July, only in June. I guess I've gone to bed too early.

Well I am looking right now and I can see them. I am up an hour before dawn. Well half an hour now, and although I am near Toronto, not exactly polar region I can see mostly an opaque red and yellow glow very like what is on the horizon in the photo only much bigger, and I can see noctilucent cloud streaks. Just a couple and they are horizontal very similar to what is seen just above the clump of trees in photo at centre right. Can't see the more obvious vertical veins though. Maybe because our weather is warm with overnight temps in the low twenties.
