Cosmic Calendar Poster with Doomsday Clock
The Cosmic Calendar is a scale that helps to conceptualize the vast amounts of time in the history of the universe in an understandable way. The concept was first popularized by Carl Sagan on his television series Cosmos.
The sections are divided up into the following: the Calendar; the Key; Doomsday Clock; The Legacy of Carl Sagan and New Year's Day.
The photograph of Earth by Voyager 1 at 3.7 billion miles (as it was leaving the solar system), which Carl asked to be promoted, is also included!
