NASA is well-known for producing some of the most stunning space images in history. And this week, the space agency has delivered something a little different -- an ancient stargazer's tool that turned our idea of early astronomy on its head.
The Antikythera mechanism is an analog computer used in 80 BC to calculate astronomical positions. Discovered on the ocean's bottom aboard an ancient Greek ship, the device is far more sophisticated than historians expected. In fact, the technology was not thought to be developed for another 1,000 years.
