Who made the spherical astrolabe?
The spherical astrolabe was invented by Abū Ishāq Ibrāhīm al-Zarqālī, a Muslim astronomer and engineer from Al-Andalus (modern-day Spain). Al-Zarqālī's spherical astrolabe was an improvement on earlier flat astrolabes, allowing for easier calculations of celestial positions and timekeeping.
Use the word Astrolabe in a sentence?
An astrolabe is an old instrument used to calculate the position of celestial bodies. Here are some sentences.I found an antique astrolabe in an old store.An astrolabe was used before the sextant was invented.Polish that astrolabe so it doesn't tarnish.
Do people still use the astrolabe?
No, the astrolabe is no longer commonly used for navigation or astronomy. It has been largely replaced by more modern and accurate tools such as GPS devices and telescopes. Astronomers and historians may sometimes use astrolabes for educational or historical purposes.
What is astrolabe made of?
An astrolabe is typically made of metal, such as brass, that is engraved with various markings for celestial navigation. The device also includes a rotating arm called an alidade, which is used to measure the altitude of stars and celestial bodies. Some astrolabes may have additional components made of wood or other materials.
How do you you use astrolabe in a sentence?
The scientist used an astrolabe to find the altitude of the sun and stars.
They used what ancient Greek device to find latitude?
Astrolabe
What did the astrolabe navigation device use to determne direction latitude and local time?
the sun
What device is used to find latitude?
Astrolabe
Which is device used to determine a ships latitude?
A sextant is a device used to determine a ship's latitude by measuring the angle between the horizon and the celestial body, typically the sun or a star. This information is then used in conjunction with nautical charts to calculate the ship's position on the Earth's surface.
What is device used to determine the altitude of the North star?
The device used to determine the altitude of the North Star (Polaris) is called an astrolabe. An astrolabe is an ancient astronomical instrument that allows users to measure the angle of celestial objects above the horizon. By aligning the astrolabe with Polaris, one can determine their latitude based on the altitude of the star. This technique has been used for navigation and understanding one's position on Earth.
Who made the spherical astrolabe?

What discoveries were made using the astrolabe?
An astrolabe is a calculating device, kind of like a circular slide rule (which is probably just as mysterious an instrument to anybody under 35). One does not actually "discover" things with it so much as work them out, such as the date of the next eclipse.
What were the two navigational instruments in Prince Henry school?
compass, and the astrolabe
Why did Columbus use an astrolabe?
An astrolabe is an angle-measuring device, vaguely similar to a sextant or an octant. Holding the astrolabe by a cord, one sights through a set of peepholes to observe a star, and you can then read the angle of elevation of the star above the horizon. It's not especially accurate, particularly not when on the pitching deck of a ship at sea. Columbus would have used this device to measure the elevation of the north star Polaris above the horizon, giving him his latitude (at least, approximately...). In order to calculate longitude, one also needs an accurate clock, which Columbus did NOT have.
How does an astrolabe connect to astronomy?
== == the astrolabe is to find the altitude of a stellar object
What part of speech is astrolabe?
The word astrolabe is a noun. The plural is astrolabes.
How do you may astrolabe on alchemy classic?
