ABSTRACT:
The invention relates to a portable celestial globe called Kozmosphere, consisting of a sphere the inside of which represents the sky with the stars and the Milky Way, observed through strategically distributed peepholes, and the outside of the sphere featuring either the stars as those inside, but completed with additional astronomical data, or else, featuring the map of the Earth or that of the Moon.
To the south pole of the sphere is fastened a flashlight the bulb of which protrudes into the sphere illuminating it when switched on. The flashlight serves also as the handle of the Kozmosphere. When not used, it can be put into a vase, thus being a nice decor of the home.
The Kozmopshere can be made in three basic forms:
