Imagine that we are going on a cosmic journey at the speed of light. With each second we make as much as 300,000 kilometers. And yet before we reach the nearest neighboring star, more than four years will pass. A further journey to the limits of our galaxy is already a journey for tens of thousands of years, and really distant cosmos stretches for billions more light years. This is the cosmic distance scale. In this programme, we will show you how it is possible to measure it. Welcome to Astronarium. • Premiere: 23.01.2016 • #distance #universe #astronomy
