Time - Astronarium #19

Why does a day have 24 hours? Can a shadow replace a clock? And what could GPS and general relativity have in common? All these questions have a common denominator: time. In this programme, we will show you what are the astronomical basics of measuring time and what makes the hands of the clocks move forward so relentlessly. Welcome to Astronarium!
Premiere: 6.02.2016
