With CGI, landscape footage and some of the world's most important astronomical artifacts, Ancient Skies looks at the universe through the eyes of our ancestors, and charts our changing views of the cosmos throughout history. We take a journey through past visions of the heavens from all over the world, from those of our earliest ancestors to the recent past. From hunter-gatherers to Edwin Hubble, we'll see the myriad of ways that we have observed and imagined the heavens and explain the science behind the things our ancestors sought to explain through mythology.

Watch it tonight at 9pm on WGBH World
