It is 400 years since Galileo Galilei demonstrated his telescope, which would lead him to make new astronomical observations While many people have been loudly celebrating this year's double commemoration of 200 years since Charles Darwin's birth and 150 years since the publication of On the Origin of Species, another scientific anniversary has crept up relatively quietly, marking an event which arguably changed human thought and the way we see ourselves even more irrevocably.

Exactly 400 years ago today, on 25 August 1609, the Italian astronomer and philosopher Galilei Galileo showed Venetian merchants his new creation, a telescope – the instrument that was to bring him both scientific immortality and, more immediately, a whole lot of trouble.
