sky
Let an agent explain what the sky is, relay why it looks as it does and its role in weather, astronomy and aviation from science sources, distinguish the everyday sky from airspace as a legal notion, and describe the aliases.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain what the sky is, relay why it looks as it does and its role in weather, astronomy and aviation from science sources, distinguish the everyday sky from airspace as a legal notion, and describe the aliases.
The sky is the expanse seen overhead from the surface of the Earth, appearing as a dome that is blue by day because of the scattering of sunlight and dark and star-filled at night; the registry aliases name related notions such as airspace, the night sky and seasonal skies. In everyday terms the sky is the visible atmosphere and space above, and it is the setting for weather, astronomy and flight, though it is not a physical object with a surface.
What it is for: Not applicable; the overhead expanse above the Earth.
It can be explain what the sky is; relay why it looks blue; relay its role in weather and astronomy; distinguish it from airspace.
Distinguishing features
Seen overhead
Blue by day
Dark and starry by night
Not a solid object
What it looks like
A vast overhead expanse, blue with clouds by day, dark with stars and the Moon by night.
Physical character
location: above the Earth s surface note
day colour: blue from scattering note
registry parent: space note
How it is recognised
The overhead expanse above the Earth
Airspace, night sky, spring sky
Airspace is a legal and navigational notion; outer space is beyond the atmosphere
