An armillary sphere is a model of the celestial sphere. It consists of a set of rings representing different celestial circles, such as the equator and the ecliptic. By rotating these rings to align with the position of celestial objects, users can track the motion of the stars, sun, and planets in the sky.
What else can I help you with?
Who built pointers that he used measure the locations of stars and planets before the invention of the telescope?
Tycho Brahe, a Danish astronomer, built large calibrated instruments called quadrants and armillary spheres to measure the positions of celestial objects before the invention of the telescope. He used these tools to create comprehensive catalogs of stars and planetary positions.
How did the astronomers view the sky before telescopes were invented?
Before telescopes were invented, astronomers viewed the sky primarily with the naked eye, relying on their observations of celestial bodies and patterns. They used simple tools like astrolabes and armillary spheres to measure angles and positions of stars and planets. Their understanding was limited to the brightness and movements of celestial objects, leading to the development of early models of the universe based on these observations. This observational approach laid the groundwork for later advancements in astronomy once telescopes became available.

What is an armillary sphere?
An armillary sphere is an instrument consisting of graduated metal circles used to represent the motions of celestial bodies around the earth.
When was the armillary sphere made?

What has the author J S Slater written?
J. S. Slater has written: 'Description of an improved armillary sphere'
What does the armillary sphere do?
An armillary sphere is a model of the celestial sphere that represents the apparent motion of the stars and planets around the Earth. It consists of a series of rings, or armillae, that represent the celestial equator, ecliptic, and other key celestial circles. Historically, it was used for teaching astronomy, demonstrating the positions of celestial bodies, and aiding in navigation. Additionally, it illustrates concepts like celestial coordinates and the relationship between the Earth and the heavens.
Who discouvoed Saturn?
Ancient people saw Saturn, including Claudius Ptolemy, who used an armillary sphere - a device made of metal rings - to track all of the stars and planets.
What did Zhang Heng invent?

Who made the biggest water clock in Chinese history?
Su Song's water clock tower is the biggest because it was 30 feet tall!!!!!!possessed a bronze power-driven armillary sphere for observations, an automatically rotating celstial globe, and five front panels with doors that permitted the viewing of changing mankiins which rang bells or gongs.

What do the parts of the Portugal flag represent?
The large red band represents blood spilt in wars. The small green band represents hope. The gold (for integrity) armillary sphere represents the discoveries.

The five blue (for virtues) shields with five white (for honour) dots represent the five wounds inflicted upon christ during the cruxifiction.
What does the circle in the Army Air Corp Navigator wings represent?
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
