Human beings have always observed the sky and sky events have been given special significance since time immemorial. For example, our ancestors saw comets as symbols of the gods, and according to the state of the stars, seeds were harvested and harvested. Two further “celestial events” adorn the two new stamps of the special postage stamp series of the same name, the Kelvin-Helmholtz clouds that seem like the ridges of a mountain range and multilayered lenticular clouds that make the viewer believe that a whirlwind would have taken shape.

The imposing, bizarre Kelvin-Helmholtz clouds are among the comparatively rare weather phenomena. In order for them to develop, special meteorological requirements must be met and their lifespan is only very short at 10 to 20 minutes.

Lenticular clouds often remain stationary or mobile in the sky for several hours, sometimes taking on such unusual shapes that they can easily be misinterpreted as UFOs.
