Measuring the Universe

The Royal Observatory in Greenwich will mark next year’s June 5 Transit of Venus with an exhibition and series of talks from March through to August.
Measuring the Universe will explore the way astronomers used the rare celestial event in previous centuries to help figure out the size of the cosmos.
As well as telling the stories of early scientists and explorers such as Edmund Halley and Captain Cook, it will also highlight how the scale of the universe continues to awe and inspire us today.
