Why Atmospherium?

Atmospherium is a term that never took off, but if one wishes to build the sky, why do it only half way? A planetarium depicts (or used to) the night .. the starry realm, and wondrously effectively. This is of course back when planetariums majored in stars. They've long since relegated the stars to the background - we can see black holes revolve, we can go to alpha centauri or see the Earth being born. But no child anymore will strain to recognize that star pattern rising over the coop .. is that Cepheus or Cassieopiea? But we look up in the daylight too . the sky is never idle .. I thought and thought and decided, I liked my sky busy

Pristine darkness - the deep blue of that rare cloudless day were appealing yes. but most of my life there were other things happening .. overlooked .. the moon .. airplanes .. clouds .. glows on the horizon .. rainbows . who's even heard of zodiacal light and the gegenshein . no two snowflakes alike? try no two sunsets are alike .

So an atmospherium shows everything in the atmosphere or above it.. satellites .. vapor trails.. meteors . raindrops .. thunder and lightning

Much more difficult to reproduce? In some ways, but in some ways easier -

but just as universal to the human experience.

So why Atmospherium?

Because thats whats really UP there.
