Cosmology from Ancient Greece to Today - Webcast - Michelle Thaller, astrobiologist and assistant director for science communication at NASA Goddard Space Flight Center. According to Thaller, ancient Greeks had sophisticated, gear-controlled astronomical computers, which remained unrivaled in accuracy and complexity until the 18th century. With the advent of space-based observatories and supercomputers, the Earth’s position has been mapped relative to millions of other galaxies covering billions of light years.
