Measuring the Universe

This video illustrates the complexities of measuring distance in our universe with simple, easy to understand examples and animation. Part of an exhibition called “Measuring the Universe: from the Transit of Venus to the Edge of the Cosmos” at the Royal Observatory Greenwich, the film is being shown in order to help people understand how we are currently trying to measure the vastness of space. The exhibition runs from March to September, and is held in honor of the last transit of Venus across the sun for 105 years.
