Here's what researchers know about the ancient Antikythera mechanism, a celestial tracking device discovered in a shipwreck off a Greek island.

A hand-powered clock from 2,000 years ago revealed a big secret with new astronomy research. The Antikythera mechanism's calendar ring likely followed the lunar year.

Researchers previously thought the calendar ring on the Antikythera mechanism tracked the ancient Egyptian calendar, but new research suggests it tracked the Greek lunar calendar instead.

A quick dive for sea sponges resulted in the discovery of a mysterious, surprisingly complex machine often referred to as the world's first analog computer.

The Antikythera mechanism is an ancient mechanical analog computer (as opposed to digital computer) designed to calculate astronomical positions. It was discovered in the Antikythera wreck off the ...

The Antikythera mechanism was discovered over 100 years ago. Researchers think they solved the ancient computer's mystery with statistical techniques.

By Gary Todd The Antikythera Mechanism is a bronze gear mechanism from ancient Greece that was discovered in a sunken ship near the Mediterranean island of Antikythera in 1901. New research ...

The name, Antikythera Mechanism, was proof of the scientists’ uncertainty and confusion. Antikythera designated the place of discovery and mechanism that it was some kind of a machine.

Scientists used an analysis technique from gravitational wave astronomy to suggest the Antikythera mechanism had a lunar calendar.

New insights on the Antikythera Mechanism Poor spacing between gear teeth could cause blockages, rendering the mechanism unfit for scientific use, simulations indicate.
