It has happened so often this summer, it hardly feels like news anymore. But it is. On July 4th, noctilucent clouds (NLCs) swept across Europe. There was "a large display" in Belgium, and a "stunning, amazing" show in Germany. In Slovakia, the clouds lingered so long that photographer Matej Sekeráš had time to pose his nieces in front of them.

"It was the first time we witnessed these incredible clouds," says Sekeráš. "The electric-blue ripples were visible for nearly an hour."

At the apex of the display, NLCs descended all the way to northern Italy. "I saw them from Sumirago at latitude +45N," reports Paolo Bardelli. "Another emotional night!"

NLCs are Earth's highest clouds. They form when summertime wisps of water vapor rise up to the edge of space (~83 km high) and crystalize around disintegrated meteoroids. When you see one, you're literally seeing a cloud of frosted meteor smoke. The best time to look is during the hours before dawn or just after sunset.

These articles on noctilucent clouds are from just last month:

• Noctilucent Clouds observed from Granada, southern Spain, for first time
• Major outbreak of noctilucent clouds over SOUTHERN Europe, as night-shining clouds AGAIN appear at record-low latitudes
• Rare 'night shining' clouds put on a dazzling display across Calgary, Alberta

As explained in Pierre Lescaudron's book, Earth Changes and the Human-Cosmic Connection:

The increase in noctilucent clouds is one of the effects - among others - of increased dust concentration in the atmosphere in general, and in the upper atmosphere in particular. We suspect that most of this atmospheric dust is of cometary origin, while some of it may be due to the recent increase in volcanic activity.
