1. In October 1971, a physicist and an astronomer took 4 cesium-beam atomic clocks aboard commercial airliners. They flew twice around the world and when reunited, the sets of clocks were found to disagree according to the predictions of the relativity theory

2. At the center of most astronomical clocks is a sphere or a disc meant to represent the earth.

3. Today it is possible to buy astronomical watches, some designed by famous clockmakers such as Christiaan van der Klaauw.

4. Astronomical clocks are all different but share common features such as displaying the time of day, the calendar and zodiac, moon's age, hour lines, aspects, and eclipse prediction.

5. In 1092 Su Sung, a Chinese Polymath designed and built a 30 foot high water-driven astronomical clock. There is a full size replica in the National Museum of Natural Science in Taichung City, in China.

6. Galileo Galilei invented two devices to help determine longitude at sea, using Jupiter's four largest moons as an astronomical 'clock'

In 1900, an ancient bronze and wood device was discovered on a Roman era ship in the Aegean Sea. Dating to the 1st century, the clock-like device was called the Antikythera Mechanism. It was used to track dates and astronomical phenomena and is believed to be the world's first computer.

In 1206 a water-powered astronomical clock was built. It is known as Al-Jazari's castle clock and stood at 108 feet. This design had multiple functions such as displaying the zodiac, displaying lunar and solar orbits, and had "musicians" that played when moved by levers that were attached to a water wheel.
