What is out there?
Galileo was the first person to look into space using a telescope. His observations of Jupiter and Saturn helped us to understand that other planets aren’t just points of light, they are other worlds.
In this book Galileo defends his invention of a new type of compass. He has handwritten the dedication on the left-hand page.
The methods and equipment that astronomers use to spot exoplanets build on technology we’ve been using for 500 years.
Transit telescopes, for example, were once used to accurately measure the movement of a star. We now know that it is the Earth that is moving, not the star.
