A reboot of Carl Sagan\'s \"Cosmos,\" the 1980 PBS series that explored all aspects of the universe, is hosted by astrophysicist Neil deGrasse Tyson, and begins with a look at the work of 16th-century Italian astronomer Giordano Bruno and a walk across the \"Cosmic Calendar,\" a football field-size time line that starts with the Big Bang and ends with humans\' first appearance on Earth.
