Considered one of the most remarkable feats in Metallurgy, the seamless globe was invented in Kashmir by Ali Kashmiri ibn Luqman in 998 AH (1589-90 CE), and twenty other such globes were later produced in Lahore and Kashmir during the Mughal Empire.
Celestial globes were used to represent the stars and constellations of the night sky and record their positions with respect to each other and a co-ordinate system. They were also used as analogue computers to resolve problems involving the stars. In the most common form of celestial globe, a number of stars were marked on a sphere, and the constellation figures delineated. The sphere was mounted by its poles (corresponding to the celestial poles) on a metal circle, or meridian. The ecliptic and equator were marked and divided (into degrees) on the globe, to measure celestial longitude and right ascension. Declination was measured using divisions marked on the meridian. The globe was placed in a stand, which included a broad horizontal band, known as the horizon. The elevation of the pole of the globe above the horizon could be varied to adjust for the user's latitude. Once so adjusted, the rotation of the globe was analogous to the (apparent) diurnal rotation of the stars, for that latitude. Since the ecliptic and equator are marked, the globe could be used to work out the times of rising and setting of the stars, or the time of their culmination (the time when an object reaches its highest point in the sky).

Celestial navigation has been used for centuries by various civilizations, but its modern form can be attributed to early astronomers like Hipparchus and Ptolemy. They developed mathematical models to predict the positions of celestial bodies, which sailors later used to navigate the seas.
Celestial globes show the apparent positions of the stars in the sky. They omit the Sun, the Moon and planets because the positions of these bodies vary relative to those of the stars, but the ecliptic, along which the Sun moves, is indicated.
The earliest known globe was constructed by the scholar Crates of Mallus in Cilicia (now Çukurova in modern-day Turkey) around 150 BC. An ancient celestial globe that still exists was made about 150 AD as part of a sculpture, called the Farnese Atlas, in the Naples Museum, Naples, Italy.[1] The first globe of the Old World was constructed in the Muslim world during the Middle Ages.[2] The oldest existing terrestrial globe was made by Martin Behaim in Nürnberg, Germany, in 1474.[1] A facsimile globe showing America was made by Martin Waldseemueller in 1507. Another early globe, the Hunt-Lenox Globe, ca. 1507, is thought to be the source of the phrase "Here be dragons."

celestial globe is a physical model of celestial sphere
In the past I have read a book called 'The Celestial Globe'.
The Celestial Globe (or sphere) is an imaginary sphere around our planet, earth. All objects in the sky and space, such as satellites, can be thought inside this invisible sphere.
I think Albert Einstein invented the light globe
Also known as astrolabes and armillaries.
Yes, "globe" is a noun. It refers to a spherical representation of the Earth or another celestial body, or a spherical object.

The word "globe" can function as a noun. It typically refers to a spherical representation of Earth or any celestial body in general.

I don't know for sure, but it looks identical to a Celestial Globe, which was an ancient navigation tool used by sailors. Also known as an armillary sphere (variations are known as spherical astrolabe, armilla, or armil), this was a model of the celestial sphere that present the stars in relation to the earth. Link illustrates what the Celestial Globe looked like. It did have a globe mounted in the center of several rings. http://en.wikipedia.org/wiki/Armillary_sphere
