Galileo's Telescope : The Instrument That Changed the World

This is a celebration of the 400th anniversary of Galileo's accomplishment and the remarkable discoveries he made.

In July 1609, Galileo Galilei received news that a Dutch optician had invented a device that allowed people to see distant objects as clearly as if they were nearby.

As soon as he discovered the technical and mechanical details of the device, he dedicated himself to perfecting the instrument.

Urged on by an insatiable scientific curiosity, Galileo turned his telescope to the heavens.

His research revealed unexpected features and behaviours of the known planets and stars, as well as adding new heavenly bodies to the Ptolemaic Cosmos. "Galileo's Telescope" is published to coincide with the 400th anniversary of Galileo's remarkable discoveries, and offers readers an unrivalled glimpse into the instrument that changed the world.
