400 Years of the Telescope

This lecture coincides with the 400th anniversary of the first use of a telescope to observe the heavens by Galileo Galilei in 1609. It will chart the development of optical telescopes since then, the subtle ideas that are greatly improving their performance and how they are bringing ever further parts of the universe within our reach.

Ian Morison is an astronomer and astrophysicist who served as the 35th Gresham Professor of Astronomy.
