The publication of Copernicus' book, De revolutionibus orbium coelestium (On the Revolutions of the Celestial Spheres), just before his death in 1543, is considered a major event in the history of science. It began the Copernican Revolution and contributed importantly to the scientific revolution.

The observations of a 14th century Polish monk sparked the Scientific Revolution and profoundly altered the trajectory of humankind. The Webb Telescope (scheduled to launch in 2018) will be yet another milestone along the trajectory that began with Copernicus over 500 years ago, as we will soon peer into the furthest reaches of outer space and back in time to the 'Big Bang' 13 billion years ago when the universe was created.
